I think these may fix your problem with the two HV conditions. The components are an AD7501JN and an AD7506KN. The AD7501JN is to replace MX1 on the Ampli Corrections board and the AD7506KN is to replace MX32 on the Column Control Board. Please note, the AD7506KN should be on a socket and the AD7502JN may be on a socket. I am sending you sockets for both IC's. Next issue, the secondary gauge may be heavily contaminated and it may take a moment or so to get started. Before the gauge gets started you will get a instant vacuum reading of 4E- 5Pa. To get around this for the time being, just tap the sec. gauge and it should return to normal. Please note the sec. gauge may need to be rebuilt. When was the gauge replaced last?

Some users like to use a rastered beam at a magnification of about 8000x. Fixed verses rastered does not seem to make much difference. We typically use a counting time of 20 seconds for Na and place it first in the Declare file. I like to use Tiburon Albite as a Na standard. I measure the background at +1200 and apply a "slope" of 111 (using TAP) to get the below-peak background. For K I use 30 seconds counting time, Orthoclase as a standard, a background offset of 800, and a background slope of 1.07 (PET). I have not had a problem with K loss. We get good results analyzing VG2 and/or A99 as a calibration check. I hope this is of some help. Our procedure is pretty standard, but seems to work. Good Luck! Tom H. From ???@???

Defocused beams of 10 to 20 um in diameter are superior to rasters simply because the flux is more even over the irradiated area. Just put the beam a Zn2SiO4 and look at the distribution of light; it will always be brighter on the left hand side of the raster, and even greater in the upper left hand corner. 2. Depending upon the total Na content (I have never encountered problems with K, and I've analyzed ALOT of K-rich synthetic Si-based glasses) I would simply decrease the beam current. You can do surprizingly well even at 5 nA...experiment yourself with this. 3. I believe the extrapolating to t0 is necessary in few cases. However, I do perform the test if the results are poor. I have done this "manually" although there is no reason one couldn't put together a task stringing pcou spec# 500, cou spec#,while writing to a file. 4. If you've got an alkali problem (ie decreasing counts, by the way check your Mg also) you also probably have a Al and Si increase. Why? interdiffusion in some form or another.

At present, I don't have a preferred date, but I will be there from Nov. 4-10. I have a poster on Thurs., Nov. 9 1:00 - 4:00. Also, do you have a set of good garnet standards? Greg Dipple told me that your lab does lots of garnet work and has a lot of experience in this regard. I have been using the standards that were here in my when I arrived 3 years ago, but I am not happy with them, and we have a lot of people who will want to do some good garnet analyses this fall. Our commercial diamond-indicator work has not been affected. In particular, my grossular gives slightly low Si values on unknowns, although Ca and Al are good. I don't have a reliable pyrope or spessartine. The ones I got from Taylor 2 years ago do not check out well. I got an almandine from Carl Francis at Harvard that was characterized for oxygen work and seems OK. I have been using Mg from diopside, but it gives slightly high values on pyrope unknowns (checked by other labs). Do you have any spare material that might help me out, or do you know someone else who does? I don't want to put this request on the Users' Network, as I have had problems relating to this matter with a certain commercial lab. In general, I have heard a lot of anecdotal evidence about garnets being somewhat peculiar with regard to EPMA. It seems that I can analyze just about any oxides or silicates against each other with consistent results, but garnets definitely behave differently. I wonder why there should be such a difference, as the matrices are not substantially different? In any case, I would appreciate any suggestions.

Ian has filled me in on his setup and the modifications he had to make to hardware and software, and has been quite positive about the usefulness and quality of the applications that can be run. Our SX50 runs on SUN 3/260, so your setup should be closer to what we could have. Cameca has quoted approximately $8,000, given that we already have SX-LATCH (?). Would you like to pass on your comments? ( positive and negative, of course). Todd Solberg also suggested I make sure that the Cameca-supplied system works with both FCIAP and CIAP, something that it did not occurr to me to raise when talking to either Ian or Sam Pindrys. Here, the interest is from zircon dating researchers who were recently exposed to the application of CL to imaging zoned zircons. Thank you for your help. Regards. Claudio From ???@???

John, The method that I use to generate comments is to use the "Display Label" program under the "Utilities" menu (cam_exec 4 "cam_label"). This allows you to create several individual comment boxes which can then be moved into position onto the FCIAP image. You can then use the "Region" option of Hardcopy to capture everything. If this older Cameca utility does not show up under the Utilities menu on your machine, try typing "cam_exec 4 "cam_label"" to see if it still may have been compiled but not installed in the menu. If it hasn't been compiled, and if you purchased the Cameca source code option, look in the /home/sx/src/camtool directory to see if it exists there. If it isn't installed at all on your machine, after you obtain Cameca's permission I can e-mail you the source code for the utility so that you could compile it and install it on your cpu. (Cam_label is compiled as part of the Cam_merge utility package; you might have to modify the camtools Makefile to compile it) Andy Davis would be the person to contact. Good luck, and let me know if I can be of any help.

I am pleased to here that Matt uses pyroxene standards as I can see no reason why this should not be OK for garnets in light of the reduction routines that we are using. I am convinced that my problem is simply lousy standards to begin with that have been used here long before me. I have some good pyroxene standards and will try them out. I'll let you know how it turns out. In any case, how do you explain the huge number of anecdotes concerning garnet EPMA. Everyone, it seems, says that "well, garnets are always a problem!" Except for the problem of evaluating analyses of hydroxyl-bearing species, I can't think of a single reason why garnets should behave any differently than other silicates. I have a grad student who needs to check this out for his thesis, so hopefully I should know soon what the bottom line is.

Short reply now, more later perhaps. I doubt whether any quali scan will detect gold in sulphides at normal levels. I think one can get almost 1% gold in arsenopyrite, but this is rare!!. The "hole-in-the-background", explained in X-Ray Spectrometry, Self, P., et al... is about 700 ppm deep I recall. If you take the backgrounds further out, well away from the hole, you are more at the mercy of non-linear background shape, so you are likely to get the wrong answer at low levels if you use only two backgrounds. We normally try to bring the background positions in as far as possible, to minimise the errors in estimating the background under the peak position. We hope to look at ways of better estimating the background levels under the peak. A student of Jim Graham's at the University of WA has recently finished a PhD looking at the occurrence of gold in arsenopyrite. I should read his thesis. Mark Aylemore is his name. We are having very considerable trouble looking at gold in sulphides which contain zinc. There is sufficient spill from the Zn Kb peak to be nasty. We do not have slits on our spectros, so if you have slits on your LiF spectro you may have less trouble. We should try to find ways to compensate for the overlap. I am interested in problems with the Cameca pha's which mean that high-order lines interfere much more than they should. This has been a real problem to us. Sam Pindrys sent us a fax of some significant mods to the pha boards. Do you know anyone who has tried them. We have not yet.

We have been thinking about improving our trace strategy recently, but there has been no action at all. It seems, from an antipodean safe distance, and at risk of being a touch direct, that... your questions seem to have a slant which is reminescent of the Cameca application lab. That is, more focussed on, major elements, backgrounds always at 500 units each side, and high count rates etc. I will provide some equally broad statements, which have an element of truth, but should not be taken as gospel. For traces, the rules change. 1 The background is never flat or even linear (so we normally come as close as we dare, 150-250 units) 2 There is always at least one analytical problem per element per matrix. (overlaps, non-diagram lines, high order peaks and imperfect phas) 3.The only problem with traces is the estimation of the level of the background at the peak position in the matrix when there is none of the element present. 4. The standard most important is the same/similar matrix known to have none of element X. Sometimes I approximate by trying pure Al, pure Si, pure Fe etc, as all minerals have lots of els 5. It is not necessary (nor normally possible) to have analysed standards low in X in the matrix. 6. Count rates are crucial 7. Deadtime is a problem one will never have with traces, as one is always struggling to find counts, not worrying about having too many. (if strategy 8 is used) 8. We collect data on standards, pure elements, at low currents, then turn it on full for traces. 9. We have not yet done any ZAF corrections on traces. !!! Reasons. (a) we are lazy, (b) the statistical errors are normally greater than the ZAF errors (c) people are often interested in relative answers more than absolute. We should be more fastidious. As a rule of thumb, if one has to worry about ZAF correction, then one is above "trace" levels. One could derive a single ZAF factor for that element in that matrix and apply it all the time. We effectively assume the ZAF factor is 1.0 10. Our secret of traces is brute force. More KV and more nA. Yes, one does lose spatial resolution, but one gains chemical resolution. 11. If one is measuring traces, one can not determine major elements at the same time. (deadtime etc) Future: We are thinking of getting smarter ways of estimating the background than the traditional one point each side linear guess. One can model the background and then collect a small number of points to enable one to estimate what it would be at the peak posn. Our system (CSIRO-Trace) stores the pha settings for all elements used, so we can have separate biases for each element. We normally follow Cameca and move the window. Yes, moving the bias can be a good way of moving a low-energy peak up away from the low-energy noise. Haven't tried this, but the software won't mind. It would save you a lot of time if you use CSIRO-Trace, as it is a reasonable system for traces. We normally do major-element analyses at low kV and low nA (15/30) on a set of coordinates, then come back to do the trace elements on the same points at high kV and high current. We can only get to 450 nA, as the high-current was an option on the early probes. Yours can get to 10mA. I have seen some spectacular craters made when people who normally turn the beam on and then think afterwards, try that strategy on araldite at 40kV and 5000nA.!!!!. One crater in Helsinki, and one in Hawaii. There was some catalytic effect from my presence in the lab. I have an invitation to go back to the Geological Survey of Finland sometime (mid-winter?), so if you had a need, I could drop by and we could play traces. I have still never been to continental US. My trip in April 94 was my first to North America, so I am not among the frequent flyer jet-set.

Davis or whomever ? handles SX50 software problems Cc: cameca@world-net.sct.fr, valley@ice Andy: My frustration level with Cameca's software continues to grow. I know that software is not your job and that you try to do what you can, but then who is responsible?? Obviously, the ball quickly falls back in Cameca France's court, who apparently place our concerns at the bottom of their list of priorities. Specifically: Based upon complaints by a major user here, I investigated his complaint that. after the fact, he found that all his analyses were based on an old, out of date calibration file -- despite his choice, in Declare, of the calibration file he had just created minutes before. I also just found that the "Update Declare" option does NOT work. Great. You select "update declare", then 3-4 seconds later (assuming that you know you're supposed to wait for something, that the button does not just do it), a list of "old" calibrations is presented. After "select all", then pushing the button to update -- they disappear -- from the screen. You can open up the utility window (or quit Quantiview - no difference) -- they are still there. Is there some secret key combination I'm supposed to use to make it work? Other ongoing problems that continue to upset me and make me quite interested in learning about alternative software such as XMAS: The overwrite (NOT Append) of the data (.kex, .cor) files when XYZ is selected to do unattended line scans. This has caused several users to loose hours of time, when they restarted XYZ without knowing of this bug I look forward to hearing from someone the variable names that I need to use to taylor my report files. Maybe someone in France has that information? 1) date of original analysis (date of printout is worthless), 2) x,y,z coordinates of each point Looking forward to getting some help, I remain, John Fournelle John Fournelle Electron Microprobe Lab Internet:johnf@geology.wisc.edu Dept of Geology & Geophysics Office: (608) 262-7964 University of Wisconsin Lab: (608) 265-4798 1215 West Dayton Street Fax: (608) 262-0693 Madison, WI 53706 Amateur radio: WA3BTA/9 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

We tried to get them to offer a parts only (no service visit) contract and they simply would not hear of it. They spent over 6 months not responding to us and then finally said it was not possible. We could not afford a standard service contract and were looking for ways to continue some kind of service contract with Cameca. They were unable or unwilling to consider anything but their standard service package. Thus, we are without a service contract but they will swap boards and charge us for fixing ours. We are in the Sweet years of our probe, so I do not expect to need their help very often. We did not have a service contract on our old MBX for many years and were fine. However, the SX-50 has been a more difficult beast for us. On another matter, we recently bought a UPS and found that our troubles with boards hanging up decrease tremendously. Although Cameca does not recommend UPS, I think we made a serious mistake in not buying it when we got our SX-50. It cost about $8 k.

After a few hours of looking at the source code, I am not much closer to my goal. If anyone out there has had any success, or perhaps has an older version (Andy Davis says he thinks maybe the 'analysis date' may have been a feature added at one point, but left off of later versions) with the things I'm looking for in it, please let me know: What I would like are 1) The date (and time even) of the (quanti) analysis, on the "raw" printout. The calibration printout has a starting and ending time of the calibration and I can't even find in the code where that is called for. 2) Similiarly, having the analysis date on the "report" printout would be great (now it just prints out the date of printout...which I can do without). 3) Has anyone figured out (since Cameca sure hasn't!) how to correct the "overwrite" default on the XYZ - automated mode analysis in Quantiview? Cameca fixed that in the regular Quantiview "Analysis" this past release, but I have had at least 2 users loose large amounts of data when they inadvertently erased all their data by restarting XYZ to set up new lists of points. I have again spent hours looking over the code, but that blasted line escapes me! --John Fournelle John Fournelle Electron Microprobe Lab Internet:johnf@geology.wisc.edu Dept of Geology & Geophysics Office: (608) 262-7964 University of Wisconsin Lab: (608) 265-4798 1215 West Dayton Street Fax: (608) 262-0693 Madison, WI 53706 Amateur radio: WA3BTA/9 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

The reason I suspect this is that in one of the early versions (1986-88) the program generated many versions of the XYZPOS file. Then it quit doing it; it overwrote the previous file, causing grief to students who exiting the program so I then wrote instructions for playing with version numbers and concatinating files. I looked at the code, even compared the older and newer versions and found no difference; Andy suggested maybe it was the operating system. This doesn't solve the problem, but perhaps you'll feel better about not being able to solve it. Maggy Piranian Memorial University of Newfoundland Dept of Earth Sciences From ???@???

Since the SEMQ lets you mount only 2 crystals per scanner, we may be limited to a 95-angstrom pseudo (otherwise we lose the ability to do O and N). Do you have any advice on doing boron?

Interesting problem. My guess is that you have some preferred orientation in those dendritic MoB phases. As a result, you are seeing a pronounced crystallographic effect in your BSE image. In essence, there is some electron channeling occurring that becomes more pronounced at higher kv. This may be due to the increase in excited depth at higher kv causing an increase in the fraction of BSE's that channel versus those that scatter out of the specimen. Unfortunately, your probe probably does not have tilt. This can be used to help diagnose such a problem. Perhaps you have an SEM with tilt and a BSE detector? Possibly you should consider texture analysis via XRD. I have seen this effect on other specimens but not dendritic phases. It usually occurs on large grains in various metals, and especially in inter-metallic compounds. Good Luck...

John, Although I'm not certain whether this is the effect you're seeing, it is somewhat well-documented that electron channeling contrast will exhibit contrast reversals upon certain changes in energy. The way to check whether channeling is important here is simply by tilting your sample and seeing whether the contrast changes, for a constant beam energy. I looked at your web images, and at first glance, it wasn't apparent to me whether that was a channeling effect. Another possibility: is there a chance that at the lower energy, you are sampling some kind of thin, high Z overlayer in the bright regions (contamination or another phase or ...) which is for the most part fully penetrated at 25 kV? For a very thin overlayer, the EDS signal may not see it well. Regards, Bob Keller NIST Materials Reliability Division Boulder, CO From ???@???

Sam: It is 8 PM Wednesday and something is definitely not right with the vacuum system.... Here's what happened today: At 9 AM Wed AM the chamber (after pumping all night) was at 6 e-3, and the spect at 2 e 1. Around 10 I talked with you. I vented the system, checked the chamber O-ring, and the O-rings on the arlk door -- nothing seemed bad. So I removed the 3 low P spect windows and replaced with the blanks (THANK YOU for that tip!) Closed it up and pumped - but could only get to 7 e-3, like before ...on a hunch, I checked the bubblers - which had been ok the day before, and noticed that SP1 did not seem right, that the bubble not coming out the tube. I tried to slow down the gas flow to try to see if I could see the fluid go up the tube, and bam! a mad rush of bubbles started coming out the bottom. So I figured that something had happened to break that window (which was ok before). I vented the machine again, and replaced the detector window -- but the one I had (which cameca supplied me and was brand new) looked like it had a thin imperfection - like a hair or wire laying on the surface - and was on both sides of the window - but that's the only one I had, so I put it in... Pumped down the machine again...started getting "Column primary vac problem" message. I checked the status of the valves etc, and SG=off. What does that mean??? The secondary gauge is off??? The vacuum, though was back around the 7-e3 level or so... I called your office hoping to find you, but guess you were still traveling. Since I didn't know what to do next, I figured I'd do something I had planned to do Friday now, since no probing was possible -- I baked out the traps, and then changed oil in RP1 and RP2. A few hours later, when that was done, I pumped down again....now all I can get is 4 or 5 +2 in both chamber and spectrometers....and sp1, 2 and 4 are all bubbling like mad with the P10 turned off..... I really think some part of the vacuum system has failed.... I should be in Thursday morning about 8:15 or 8:30 my time. john John Fournelle Electron Microprobe Lab Internet:johnf@geology.wisc.edu Dept of Geology & Geophysics Office: (608) 262-7964 University of Wisconsin Lab: (608) 265-4798 1215 West Dayton Street Fax: (608) 262-0693 Madison, WI 53706 Amateur radio: WA3BTA/9 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

Carpenter) Subject: Re: SEM/EMPA: Anomalous BSE contrast...why?? Status: RO On the continuing discussion of "strange" BSE contrast, especially at low KV: There is a slight energy dependence (i.e. accelerating voltage) of the backscattered-electron coefficient (eta) as a function of atomic number at 15-30 KV. For example, see figures 3.13 through 3.15 in the Goldstein text (Scanning Electron Microscopy and X-ray Microanalysis, but hey everybody has this right?). As you know, the atomic number dependence of eta is strongest over the low atomic number range, so that is where BSE contrast is greatest. It has also been pointed out (MAS talks in New Orleans or Breckenridge) that eta may show strong KV dependence as well, especially at lower KV. Compare the values of eta for 5 KV with those for the other values; they are the highest for low atomic number and the lowest at higher atomic number (figure 3.15). There also appear to be some values of eta that exhibit contrast reversal (see fig 3.14). So you could in fact see contrast reversal when comparing BSE intensities between different accelerating voltages. As others have suggested, the low KV regime is affected by contamination, and since we are really talking about surface analysis when at 5 KV, it is certainly possible to see contrast reversal due to the competing effects of surface properties coupled with the (as yet imperfectly understood) effects of eta dependence on KV. I'm sorry I don't have the original post, but I recall we are talking about alloys in the B-Si-Mo system. Despite the best of sample prep methods, it may be that there is surface oxidation (or some other reaction product) that is making itself known to you at 5 KV that was not as important at 15-20 KV. It certainly is an interesting aspect of microanalysis. Paul Carpenter +----------------------------------------------------------------------+ | Paul K.

The images are a bit grainy -- certainly not as good as those from a $2k framegrabber card -- but usable for occasions where reflected or transmitted light images of probed areas are desired for documentation. Very quick and cheap too. 3) Interesting/unexplained BSE contrast change (This was posted on the Microscopy list, but I'm putting it here for those who may not subscribe). A user here working in the Mo-B-Si system has observed that a MoB dendrite phase shows high BSE intensity (is white) at 5 kV, but at 25 kV shows very low BSE intensity (is black), and there is a switch over between 10-15 kV....We are asking for suggestions folks might have, and any possible references in the literature to other observations of this. Some suggestions so far are electron channeling, or possible 'anomalous' responses by the solid state BSE detector to simulataneous signals (light, x-rays).If interested, check out the writeup and images at http://geology.wisc.edu/~johnf/sx51.html ========= John Fournelle Electron Microprobe Lab Internet:johnf@geology.wisc.edu Dept of Geology & Geophysics Office: (608) 262-7964 University of Wisconsin Lab: (608) 265-4798 1215 West Dayton Street Fax: (608) 262-0693 Madison, WI 53706 Amateur radio: WA3BTA/9 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

It takes maximum contrast to image it in silicates, although we have occasionally seen it in twinned plagioclase. The intensity of BSE should not depend much on operating voltage for the same beam current unless the electrons are not always striking the sample in the same place with the similar sample currents (i.e., if magnetization or charging effects are perturbing the electrons). If it is variable fluorescence this may be checked by looking for an optical effect. We notice little effect on the BSE of natural willemite with intense and variable green fluorescence.

It is quite easy given the poly and patience (also known as PaP). It would be much easier to show instead of describe. Admitedly, Cameca's windows are slightly thinner and more uniform, but also expensive. Do you get to Chicago? If so stop by and we can make a few. Otherwise I'll try to describe. I use 1 mil poly but my Brasilian friends have found a source of 0.2 mil poly. How dit the CL imaging come out?

Thanx in >advance ... ____________________________________________________________ __________________ This sounds to me like a lack of current necessary to activate the secondary valve. We have encountered the identical problem, although it only occurs when we cool the inside of the specimen chamber using the liquid nitrogen cold plate. In this case the vacuum improves VERY quickly to the high-mid 10E-5 Pa. So quickly, apparently there is no way to activate the gauge. It seems odd that such a problem can be brought-on by a system that is "too clean" and pumps down "too quickly" but this is the explanation we have received here in Princeton. Since you state that the problem is chronic, I take it that this is happening at room temperature. Anyway, read the pressure shortly after issuing the PUMP command to determine if your vacuum pumps are on steroids.

I was in early this morning for this problem, but 6AM???????? Anyway, the problem you talk about (I think) is the Penning gauge refusing to "fire" which at times can be caused by "too good" of a vacuum, which explains your coincidence with LN2. It happens to me all the time. I wouldn't be too fearful of banging on it ... just don't use a sledge hammer. I tap the sensor with the metal end of a long small screwdriver because I think metallic sonic vibs due the trick. ^My^ problem was the vacuum logic never switching to the Penning gauge ... it would just sit there at 1E-1 for hours. As many users pointed out I had a leaky detector window ... I replaced it this morning and the Cameca it alive and ready for albitized feldspars (booooorrrrriiiiiinnnggg). For the rest of the SX users, be aware that upon inspecting the window after replacement, I didn't find any specific pin hole. What I saw looked like an aging process ... many linear cracks parallel to the support grid openings. I wouldn't have thought, but my vacuum is orders of magnitudes better ... pump time, ion pump lookin' good. Anyway, my point for all of you might be that you might want to put low pressure detector windows on a 4-5 years R&R, at least have a couple handy. cheers, shaf <\/>/\<\/>/\<\/>/\<\/> cognito, ergo zZOooOM <\/>/\<\/>/\<\/>/\<\/> Michael Shaffer, R.A. - University of Oregon Electron Probe Facility mshaf@oregon.uoregon.edu -or- mshaf@darkwing.uoregon.edu http://darkwing.uoregon.edu/~mshaf/epmahome/ From ???@???

(I have 2-3 page instruction sheets for both -- and would be happy to mail/fax them to you if you'd like. Briefly -- Ar hooked up to sputterer, valve closed -- pump down to approx 100 microns -- bleed in Ar until pressure rises to 200-300 microns -- if there is a timer, set it for ~15 seconds -- turn on high voltage switch -- bring up the current to about 40 ma (should be glowing purple by now) -- if no timer, zap it for 15-20 seconds --turn off high voltage -- close Ar valve -- shut off external vacuum or vacuum gate valve (external) -- open sputter vent valve -- open chamber and rearrange specimens 180 degrees, and repeat the cycle. 30 seconds of Au should be good, but if you find not heavy enough, do the cycle a third time. You do not want to heat up the transformer (it fails) by running long bursts at one time Hope that helps. john John Fournelle Electron Microprobe Lab Internet:johnf@geology.wisc.edu Dept of Geology & Geophysics Office: (608) 262-7964 University of Wisconsin Lab: (608) 265-4798 1215 West Dayton Street Fax: (608) 262-0693 Madison, WI 53706 Amateur radio: WA3BTA/9 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

We had a good meeting: John Donovan, Peter Schiffman, Roger Nielsen, Mike Garcia and myself. I will be writing up a summary for the users group so won't go into much detail except to say the following: 1. We agreed to the importance of a regular meeting of users with Cameca, that would combine training, networking and ongoing interface-organized dialogue with Cameca. We agreed that having, say, a 2 day meeting at a location such as the AGU meeting where several users would be going anway (e.g. the weekend before or after the AGU meeting) would be optimal. A specific topic could be addressed , with maybe some tutorial on aspects of empa. etc 2. Software - this was the most difficult, but for some of us the most important, but we could not go into this -- because of the 5 SX50 users there, there was no one common software! 2 of us use the Cameca "SX-ray" (me and Hawaii), John Donovan has written his own software (vy impressive!), and the 2 others (UC-Davis and Oregon State) use Thiot's SAM-X system. So those like me will have to do some on-line communicating to get a list to Cameca vy soon. 3. Maintanence -- This is a sore spot since Cameca has no concrete list of what things need to be done, when, etc. They obviously want people to may for the service contract -- but people complained even then that Cameca service personnel are not consistent -- one example -- which I learned for the first time! -- what that the BSE diodes must be cleaned at some regular interval, otherwise the C-contamination builds up to a point where it cannot be removed (Mike Drake's experience was cited) and they must be replaced. John Donovan is compiling a list of questions to be submitted to Cameca. I have been to one other (last years AGU meeting) SX user meeting -- which was not that hot (noisy location, less people, little follow thru). I sense that our recent meeting was a step ahead and hopefully the one next year will be along the line of #1 above. john John Fournelle Electron Microprobe Lab office: (608) 262-7964 Dept of Geology & Geophysics fax: (608) 262-0693 University of Wisconsin home: (608) 274-2245 1215 West Dayton St. email: johnf@geology.wisc.edu Madison, WI 53706 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

As it turns out, when verifying SP1/TAP my SX50 "thought" it was using the TAP xtal, but actually was trying to verify TAP with ODPB on Si metal with the 4th order Si Ka peak ... no wonder it was out of range! Sooooo, now my problem is figuring out why SP1 doesn't want to flip from ODPB to TAP. I finally pulled the cover to take a look ... if I issue the "XTAL SP1 TAP" command, it rotates almost all the way around to the TAP position, but then reverses its direction and returns to ODPB ... the Cameca however "thinks" it is using TAP. If I then issue the command "XTAL SP1 ODPB", the xtal changer will not move, but the instrument will now believe ODPB is in place. I want to believe this is some type of logic problem because SP1's xtal is almost never flipped ... anyone got an idea??? cheers, shaf <\/>/\<\/>/\<\/>/\<\/> cognito, ergo zZOooOM <\/>/\<\/>/\<\/>/\<\/> Michael Shaffer, R.A. - University of Oregon Electron Probe Facility mshaf@oregon.uoregon.edu -or- mshaf@darkwing.uoregon.edu http://darkwing.uoregon.edu/~mshaf/epmahome/ From ???@???

We saw his new probe and he gave a "tour" of the software he has developed to run it. He also showed us his older ARL SEMQ, which has a unique piece of hardware -- a cryo trap above the diffusion pump -- eliminating carbon contamination (backstreaming). Neat! Around 7:45 PM we convened to a conference room and met until around 9 PM), with the following people present: John Donovan--UC Berkeley, Peter Schiffman--UC Davis, Roger Nielsen--Oregon State, Mike Garcia--Univ of Hawaii John Fournelle--Univ of Wisconsin Dan Jacobson--Cameca Western Regional Manager (observer) Tim O'Hearn, Smithsonian, "prospective SX op" 1. We agreed to the importance of a regular meeting of users with Cameca, that would combine training, networking and ongoing interface-organized dialogue with Cameca. We agreed that having, say, a 2 day meeting at an SX50 location, close to a meeting like AGU or GSA where several users would be going anyway (e.g. the weekend before/after the meeting) would be optimal. A specific topic could be addressed, with maybe some tutorial on aspects of empa. etc. Obviously, this should be planned well in advance, with a Cameca engineer and software person scheduled to be there. We did not go into any specifics (which meeting). 2. Software - this was the most difficult, but for some of us the most important, but we could not go into this -- because of the 5 SX50 users there, there was no one common software! 2 of us use the Cameca "SX-ray" (Wisconsin and Hawaii), John Donovan has written his own software (vy impressive!), and the 2 others (Davis and Oregon State) use Thiot's SAM-X system. Therefore, in the very near future, we will be conducting a poll, via email, of 1) specific requests and 2) priority of requests that we will forward to Cameca France. We have been told that Michel Outrequin (Cameca France's Applications Manager) will be spending January and February working on corrections/modifications to the software that will at some point in 1996 be available to us. 3. Maintanence -- This is a sore spot since Cameca has no concrete list of what things need to be done, when, etc. They obviously want people to may for the service contract -- but people complained even then that Cameca service personnel are not consistent -- one example -- which I learned for the first time -- what that the BSE diodes must be cleaned at some regular interval, otherwise the C-contamination builds up to a point where it cannot be removed (Mike Drake's experience was cited) and they must be replaced. John Donovan is compiling a list of questions to be submitted to Cameca. 4. Service -- West Coast users spoke forcefully to the need to their service needs, specifically the fact that the 3 hour (CA, OR) time difference not to mention 4 or 5 hour lag for Hawaii -- making it difficult to get prompt phone advice from the Cameca East Coast SX50 engineers. Dan Jacobson said that Cameca was trying to hire an experienced engineer who would be based in the West or Southwest. (Update 12/18: Cameca has hired Mr. Chavez, who was with Cameca France for 9 years as an engineer, and who then operated the U of Toronto probe. He will be based in Phoenix, and will start around the end of January) 5. Miscellaneous info: U of Hawaii reports that they have elimated the problem of the SX50 boards hanging up when the power went out, by installing a UPS -- no more pulling boards to unlock them.

I am interested in the suggestions for dissemination of maintenance information. I did not know about cleaning the BSE detectors. [As we often run at 450nA, and 30 to 40 kV, I presume our BSE detectors are getting grubby]. However, we are normally faced with too much sensitivity. The BSE system seems to have been designed to work at SEM currents, and not at probe currents. It overloads (and the signal can invert, making white black and vice-versa). We have a suspicion that unplugging the spectro motor power cables is not as safe as it has been thought. I blew a LAS 3224 24 volt power supply module in the WDS power supply while I was changing a spectrometer motor. There are some precautions, but I am not sure if it is recommended to turn off the WDS power supply before changing motors. The LAS3224 is a very pricey module, and hard to get off-the-shelf in Australia. I think it would be nice if there were a set of on-line hints and tips (perhaps on the WWW, or on a database such as Access, available via FTP) where hard-won expertise could be shared. This could take some considerable time and effort to accumulate, but would be extremely valuable to SX owners. It would be practical for labs to subscribe some money (say $100 each) to pay for the expenses and time of whoever has to accumulate and sort all the hints. Ideally one could approach Cameca in Courbevoie to contribute funds (perhaps) but more importantly expertise. It could be appropriate for there to be some reward for the people who contribute most to the maintenance etc information base. Perhaps an occasional trip to Paris, or some more modest token. It is my impression that there is no systematic repository of written information on hardware within Cameca. Perhaps that is a strength, as the French engineers are generally very good and very knowledgeable. However, it does means that it is harder for Cameca to train new engineers, and it means that users do not have access to the knowledge base. With some sort of edited on-line system, we could accumulate lots of useful hints. One would go down a menu structure, searching on keywords or whatever, to seek hints for specific problems, or just browse through. There are some minor things that we have implemented here that could go into the list. Like how to get audio outpur from the spectrometers, so one can search for a specific element, how to get the transmitted and reflected light to work at once (and with BSE and reflected light) third party sources for common components (for economy, and as a backup) commonly used spares lists. complete O-ring kit lists. I am sure that lots of other people have many useful hints. I hope we can find a way of summarising the data. The on-line WWW and internet offers a lot of possibilities.

Reply to Mike Shaffer re crystal changer problems:- It is possible to "cheat" the logic by loosening the semi-circular disk at the back of the crystal changer mechanism and moving it through about 10-20 degrees and then reclamping. ensure that you don't change the clearance between the disk and the photodiodes. Its fastened by two alan head grubscrews so you may have a little difficulty getting onto it. This may cure the problem entirely or at least it should allow you to select the crystal you require. If it doesn't help please send another message and I will give you more information on measuring logic levels etc from the crystal changer mechanism. Please let us all know how you go with it. best regards and good luck Graham --------------------------------------------------------------------- | Graham Hutchinson |e-mail:beamm@enternet.com.au | | Microbeam Services | | | 16 Alexander Street |fax 61 3 9890 6746 | | P.O. 1070 Box Hill Victoria |phone 61 3 9899 6123 | | AUSTRALIA 3128 |mobile 61 18 378546 | --------------------------------------------------------------------- From ???@???

Anderson" To: MICROSCOPY@Sparc5.Microscopy.Com Subject: Mechanical Polishing Without Water Status: O In late September I posted a query asking for suggestions on a polishing liquid for those specimens that could not be polished with water. We had been using alcohol or glycerol but our people were complaining about the odors making them nauseous (yes, we used a well ventilated hood). Also, our safety department didn't like the flame hazard. We did not want to use any oil containing liquid for fear of entrapping oil in small voids and pores in our specimens. The suggestions that came forward ranged from polishing dry to dimethylsulf- oxide (used for bruises and sprains by the athletic community), and a number of glycols. The time interval between the request and our posting the results is due to our wishing to order and try out the likely candidates before making a report. (Ordering new chemicals in a big company in the 1990s is not trivial or quick!) Nearly everything suggested worked to various degrees. Some chemicals with the same name can have an order of magnitude difference in the water, as an impurity, content. We also became more demanding with regard to viscosity and "presence" on the polishing wheel. i.e. alcohol's viscosity is too low, glycerol's is too high; alcohol evaporates too fast and has a poor 'presence', glycerol is disgusting to work with. The clear winner is Propylene Glycol. The J.T. Baker product U510-07 (500ml) has a water content of 0.03% and has a viscosity slightly greater than water. It has a slight oily feel and its "presence" on the wheel is good. The cost is higher than we would like. We have now made a number of YBCO superconductor specimens using propylene glycol and tripod polishing to atomic resolution thickness with no ion milling. The time for the entire specimen preparation procedure is 3 to 4 hours and we consume 100-200ml of propylene glycol per specimen. We are very pleased with the results. I have no affiliation with J.T.

John Fournelle writes : 1. Ion Pump: Should be automatically replaced after certain period, or wait for certain symptoms? 2. Secondary Gauge: same question 3. Column liners: same question 4. SE scintillator: same question 5. BSE diodes: should they be cleaned? at what internal? what material? 6. Optical encoders: under what circumstances should they be cleaned? how? Tom Hulsebosch writes : 1. Column overhaul - yearly cleaning, o-ring replacement, etc... 2. Gun Valve Overhaul - recommended interval?, instructions 3. Secondary Valve Rebuild - recommended interval?, instructions 4. Beam Regulator Rebuild - instructions (especially removal and replacement of the "top" aperture) and recommended replacement interval. 5. Autofocus alignment/tuning and optical microscope lamp brightness adjustment. 6. There should be a compilation of the commands necessary for resetting the SX after a power outage or electrical problems. This should include all the commands for resetting serial communications, vacuum, spectrometers, etc... Bruce Robinson writes : I am interested in the suggestions for dissemination of maintenance information. I did not know about cleaning the BSE detectors. [As we often run at 450nA, and 30 to 40 kV, I presume our BSE detectors are getting grubby]. However, we are normally faced with too much sensitivity. The BSE system seems to have been designed to work at SEM currents, and not at probe currents. It overloads (and the signal can invert, making white black and vice-versa). We have a suspicion that unplugging the spectro motor power cables is not as safe as it has been thought. I blew a LAS 3224 24 volt power supply module in the WDS power supply while I was changing a spectrometer motor. There are some precautions, but I am not sure if it is recommended to turn off the WDS power supply before changing motors. The LAS3224 is a very pricey module, and hard to get off-the-shelf in Australia. I think it would be nice if there were a set of on-line hints and tips (perhaps on the WWW, or on a database such as Access, available via FTP) where hard-won expertise could be shared. This could take some considerable time and effort to accumulate, but would be extremely valuable to SX owners. It would be practical for labs to subscribe some money (say $100 each) to pay for the expenses and time of whoever has to accumulate and sort all the hints. Ideally one could approach Cameca in Courbevoie to contribute funds (perhaps) but more importantly expertise. It could be appropriate for there to be some reward for the people who contribute most to the maintenance etc information base. Perhaps an occasional trip to Paris, or some more modest token. It is my impression that there is no systematic repository of written information on hardware within Cameca. Perhaps that is a strength, as the French engineers are generally very good and very knowledgeable. However, it does means that it is harder for Cameca to train new engineers, and it means that users do not have access to the knowledge base. With some sort of edited on-line system, we could accumulate lots of useful hints. One would go down a menu structure, searching on keywords or whatever, to seek hints for specific problems, or just browse through. There are some minor things that we have implemented here that could go into the list. Like how to get audio output from the spectrometers, so one can search for a specific element, how to get the transmitted and reflected light to work at once (and with BSE and reflected light), third party sources for common components (for economy, and as a backup), commonly used spares lists, complete O-ring kit lists. I am sure that lots of other people have many useful hints. I hope we can find a way of summarising the data. The on-line WWW and internet offers a lot of possibilities. Thanks very much for your efforts in assisting the communication between users. John Donovan writes : 1. Spectrometer/crystal install and alignment (especially for LDE multi-layers) 2.

I was able to read your mails two days later via a paper print but unable to easily send anything. So this is for me a "premiere". I think it is very interesting to collect informations to improve instrument documentation but for some of these news it will be necessary to know the options the probe has. Some tips to fix a problem can be hardware dependant. For us, installed in december 1993, our SX50 #506 is fitted with 4 vertical spectrometers, a polarized transmitted light, a backscattered electron detector, a stage autofocus system, a solflower computer (SUN) and cameca's quantiview 3.0. There is no EDS and no anticontamination device. The probe is under power 24 hours a day even during vacation. After 23 months for our FIRST maintenance under guarantee, cameca's engineer only replace the beam regulator, the diaphragms and the primary pump oil. Beside normal checking, cleaning and adjustments, the ion pump was just blown with dry compress air and the secondary gauge checked for dirt. While the engineer was working, I collected the following notes : - Stage autofocus system : spf0 wrb $66981 1 set in position the diaphragm of the stage autofocus system. You center the diaphragm versus the cross displayed on the optical image monitor (below the camera there is a small screw just above the polariser). In the same time you adjust the filament of the light (playing with the Z axis the shadows must stay concentric). spf0 wrb $66981 0 remove the diaphragm. For more informations see SX-FOC manual. - The ceramic of the electron gun was clean with acetone. - Just blow the elements of the ion pump if they are not too dirty. - Checking spectro motors : After unplugging the power cable, measure the resistance of the tachometer contacts. If the resistance value is not between 600 and 700 ohms, just spray a contact cleaner and wait until it dries. - On any capacitor of the 68000 processor boards, measure the power supply which must be 5.1 volts. Only the WDS power supply can be adjusted. After two years we fix some small problems with the assistance of cameca France : - If "dsag1 : too many spectros" appends in window "console", enter in the same window : inires esewx - If the system give "address error at #...", "unit .. not assigned" or "illegal instruction PC = ..." try to enter "spf0 init cold". If error is always there, first switch off the SEM power supply then unplug the 68000 SEM processor board for some minutes (time to discharge capacitors). Replug, switch on and start again. - If any trouble with an axis and if normal tests always fails, do the same as above but for WDS power supply and board. If you think that these informations can help SX-users, please share this mail. Regards. Jacques WAUTIER Laboratoire de geologie et mineralogie Universite catholique de Louvain From ???@???

I have found your internet service for SX50 users most useful and interesting. Of course, on this side of Atlantic, one would like to purchase things, spares etc. rather form European sources. I have tried to start an European Cameca users network using the Eudora mailing program but, unfortunately, I have got only about 10 labs on its mailing list. I have asked several months ago CAMECA to send me a list of European SX50 users, but it has not arrived . I guess CAMECA is not so eager to encourage interlaboratory cooperation. The EMAS is publishing a newsletter, which appears 2-4 times a year and is not as efficient as an email network would be, and its ment for users of other probes and SEM's, too. Maybe I should contact the editor of EMAS newsletter and make an announcement that an Europen email list has been started. If you like to contact the EMAS news editor, too, his name and email address are following: Patrick Nicholson, The University of Glasgow, Dept. Physics & Astronomy, G12 8QQ Glasgow, U.K. email P.Nicholson@physics.glasgow.ac.uk, fax +44-141-334.90.29, tel. +44-141-330.44.67. I have got the memberlist of EMAS and many of the members have an email address. Unfortunately, the list does not indicate, which of them are Cameca users. I'm not so convinced, that a separate European SX50 users network will be necessary, if the European and users of other continents (like Bruce Robinson from Perth, WA) may join your listserver. Then, your SX50 listserver would serve all SX50 users worldwide, which is quite possible. We just built up such system last summer for the Commission of Ore Mineralogy, IMA, and the server is situated in Budapest, Hungary. Best regards, Kari Kari K.

I admit not being 100% clear about all the implications of the changes you have implemented (but I am learning!) and your "adios" had such a ring of finality that I wondered if I had missed the train and any chance for redemption. I am truly grateful for all the work you have been putting into keeping communication lines alive, while I have been reaping the benefits with no work on my part. So, I apologize for not being faster on this matter. I guess from now on, rather than getting your messages delivered to door, I am to check with the listserver for any new messages. As soon as I sign off, I'll walk upstairs to talk to our computer administrator and learn or confirm a few more things. Hopefully pretty soon I'll be able to sit down and collect and pass on my thoughts on matters raised by the group in the last several weeks. Of course you know that Edgar Chavez is no longer with us, and it may amuse you to learn that you knew about it before we did. But that is another story. Take care. I hope I'll get a chance, at some point, to meet you and thank you in person. So long. Claudio From ???@???

The one at Yale sounded good, but JEOL. My roots here are too deep to consider moving, but you never know. I just received confirmation about the SX50 listserver. Nice. I'm glad you got that working. One other list I WAS a subscriber on became a bunch of long spams and I had to quit. Watch out for this. If it happens, get on top of it immediately. The closed list business is a good idea. If a new subscriber smells of something from Northern Europe, ask a few questions to be certain they are real. Otherwise, thanks for providing this important service.

We probably only have small amounts, so it depends how much you need. My guess is that all pyrite is more stoichiometric than probe analyses are accurate, with the exception that we had some with about 0.5% As once, and this was a bit of a problem. We later changed it. Hence, as long as the pyrite is relatively free from impurities, nickel, As, etc, then the Fe:S ratio can be taken from granted. I am not completely sure how reliable this guess is. If the guess is OK, then more or less any old pyrite will make a good standard. Would that all standards were readily available with closely fixed stoichiometry. I will have a look tomorrow (it is late now).

Thanks everyone who answered my calls about P-10 consumption. From the looks of it, those of us who are getting less than 3 months/tank should look for some kind of leak. However, I have also discovered that all tanks are not equal, and every company seems to have it's own system for labeling sizes. That said, most tanks physically are about XX tall, XX diameter, and are filled to XX kPA. Most folks switch to a new tank a XX kPA. Any tips from those who get more than 6 months / tank will be appreciated by all of us, I'm sure. At the end I've attached a couple notes that were particularly interesting. I still am looking for the leak on my machine. If I close the valve between the low pressure (200 PSI) side of the regulator and probe, and also the tank valve (so there is 1500 PSI in the regulator), the regulator holds pressure for at least a week. That seems to eliminate a regulator leak. With the low pressure valve closed the bubblers do not reverse bubble, which would seem to eliminate a leaking window. Plus, leak detecting fluid has not revealed any leaks around the manifold, the regulators, or the capilary tubes. Needless to say I am at a loss, but will keep poking around. Any other thoughts are welcome. Weather - ranged from a low here of -40 (C or F, take your pick!) to +40C in Perth. I'll take ours, especially since it has warmed up to a -10 C with light snow!

It may help technically, 2. Everyone seems to be adding comments about the weather. At the moment, our gas consumption is nothing unusual, but we are probably ahead of you weatherwise!! 1. P10 We get about 3-6 months on a standard (?6m**3) gas bottle (Oz for tank, I think), normally. on 3 spectrometers. One rule of thumb is that about half the gas passes through the counters, and the other half leaks through the windows into the spectrometers. The ratio will vary with the condition of the thin flow-counter windows. The output bubble rate is determined by the gas pressure, and the leakage. One way to determine the window condition is to close the gas supply valve. This leaves the low-pressure counters at 1 atmosphere, and the bubbles go the reverse way. That is, air leaks in through the bubblers in reverse, instead of P10 gas coming out, and then the air goes out through the leaks in the counter windows into the spectrometers which are at rotary pump vacuum. The reverse bubble rate then is a measure of the leakage of each window. That is, one can see if one window is leaking badly. We normally record the standard gas-flowing forward bubble rate when we change the windows. Another way is to record the bubble rate with the gas flowing, but with the spectrometers at one atmosphere. (SX> Vent gene ). This way there is no leakage in the 1 atm counters, ideally, as there is 1 atm on each side of the window and the 3 atm counters are normally well sealed with Be windows anyway, so the leaks are expected only in the thin window spectros. 2. Weather. It has been a pleasant 30 degrees Celsius here in Perth. It was unpleasantly hot, close to 40 degrees a week ago. Our house got hot and sleeping was a bit hard. However, this is not all that common. We live 800 metres from the Indian Ocean, and we (Nick Ware and I) went swimming yesterday morning, upon completion of a project to combine our WDS analysis system WANUSX with the Cameca PAP matrix correction program OFQANT. We now have a choice of two matrix corrections, on the data collected by our major element software. We will use WANUSX when we have standards close in composition to the samples, and probably PAP when we are correcting a long way (compositionally) Claudio said, joking, that it was 35 degrees Celsius and the flowers are blooming. Well, it is really summer here, and there are lots of flowers. We have been sitting by the Swan River this evening watching a firework display across the water. Any SX users who would like to visit our lab are welcome. I have trouble imagining what Alaska is like. I can picture Claudio's lab, and Toronto in April. I hope my P10 recollections are correct.

It was recommended that the tank be changed when its pressure went below 500 psi (tank started at around 2200-2500 psi). Their reasoning was that any "crud" would stay in the bottom of the tank and not contaminate the detectors. Dirty detectors would exhibit a "hystersis" or "memory-effect" such that the count rate for an element would be related to the count rate of the previously measured element. We had such behavior here and were perplexed when we would keep standardizing a high count rate element (in this case Mg from Marjalahti olivine) only to have the first analysis of that standard give a I.X:I.std ratio which was surprisingly greater than 1.000. Only when we altered the analytical procedure to remove the one previous element on that spectrometer (which was Na and had a low count rate) were we able to make the standardization "stick". CAMECA also included in that newsletter a procedure for cleaning the detectors which involved soaking the detector (minus windows and o-rings) in a 50/50 acetone/Freon mixture for an hour or so, followed by a gentle baking (150C?) for a few hours. Is this the kind of info that CAMECA gives out to SX50/51/100 users now? Or is it one of those procedures like cleaning/changing the BSE diodes that you only hear about from other users? I would like to think that communications have improved, but when I saw some of the questions that John Donovan was asking, they reminded me of the same ones we had with the MBX. Oh, yeah, weather here is cold (+7 F) and getting colder. Fortunately, we have not gotten much snow this winter (I am not a skier and prefer not to ski in the car). Landscape is flat, brown and grey.

Well, what I did was get the best possible image on the monitor adjusting beam conditions _and_ VS1, esp PM , sort of averaging over the whole area, and recorded the VS1 settings either on paper or in a TASK. I also used the same beam conditions in CIAP. After the CIAP scan started, I changed the VS1 setting to the saved values (the task below does it automagically). If setting the values manually, keep in mind that the PM will zero itself after a few seconds (after VS1 AUX), so you have to wait a little while (10 seconds is pretty safe), I think. By the time you get this, I may have an example at the URL below...I'll to find the conditions used, but it's a pretty old one..I haven't actually done any of this in a while. http://www.awinc.com/users/abauslau/em.html Regards, AB This is a task to read and/or store VS1 values for CIAP CL scans.

Also, I don't know how to post my message to him onto our board. Thanks, Nick Dear Nelson, I wound up purchasing some "Proline 20" windows from SPI, I think, but my receipt says: Diatome US 321 Moris Road Box 125 Fort Washington, PA 19034 SPI is 215-436-5400; 215-436-5755 FAX - I think I ordered from them, but I cannot remember. At any rate, the actual material was labelled Moxtek, who i know makes window material. They are at 801-225-0930 (I don't have e-mail or address for them). The windows were 2 for about $ 500. They were the wrong size, BUT: they are wonderful. You can cut the material with scissors and fashion 4 (!) windows that fit. The material has its own backing, a tiny hexagonal grid which supports the mylar. When I discovered this, I removed the Cameca brass window holder (with the support wires) and put this window directly in place where the brass was, then closed it up without the brass part. This is very easy to do because the heaxgonal grid (carbon??) makes the material quite stiff, even though the mylar itelf has no strength. The window did not hold at first, so I put it under a transmitted light microscope and found a few tiny holes (easy to see with the transmitted light). These I closed with nail polish (that is the stuff women put on their fingernails) while viewing on the scope. The window has held just fine and the count rate on the spectrometer seems about 4 times higher than with the old window (I think - I have not carefully checked my records on this as yet). I don't know if the windows were damaged in handling or when I cut them with the scissors or what. But so far this is a super deal, bringing the price of an excellent window way, way down. The window has been in for about three months so far with no trouble.

Pingitore" To: Multiple recipients of list Subject: "Windows 96" (of the polypropylene persuasion) X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Dear users, I purchased a set of two ProLINE 20 polypropylene windows for my low-pressure spectrometer. These came from EMS 1-800-523-5874; 215-646-1566; -8931 FAX; 321 Morris Road, Box 251, Fort Washington, PA 19034, USA. I asked them to aluminize the surface, and to have them fit an SX-50. They said they knew the size. What arrived did not fit at all, but it was good stuff. The super-delicate poly is backed by a hexagonal open-lattice network of stiff material (Carbon??). I cut a piece of this with scissors (yes, it is STIFF) to fit exactly the size of the Cameca brass window support - the thing with the wire arches to support the polypropylene. I replaced the brass part with the cutout and closed up. That is, the brass is no longer in the spectrometer. The window is stiff enough to hold with its own supports, and the appropriate screws still worked. You have to orient the window so the hexagonal support system is on the same side as the wire supports on the Cameca brass piece. The window leaked, so I took it back out and put it on a petrographic scope with transmitted light. Beautiful green with the hexagonal lattice work. The pinholes are easy to spot this way. I repaired two of those under the microscope with nail polish (check your nail polish with your EDS - I found some with lots of sulfur. I use nail polish for quickie grain and soil mounts). I recommend checking all windows under the scope before installation - it can save a lot of time. I don't know if the windows got the holes during manufacture, transport, or my handling. They are a minor problem. The good news is that the two sheets of the material can be cut to produce 4 windows. The set of two cost about $ 500, so this is $ 125 for each window. It has now held for three months. I think my counts are 3 or 4 times higher than before. EMS advertises these windows as extra thin, and it looks that way to me. I may try to find some old analyses to get a better quantification, but it seems that these are superior windows that are very easy to handle and install. The label on the package was Moxtek (801-225-0930) - you may be familiar with their recent series of articles on x-ray detectors in Microscopy Today. I do not know if they sell direct, but it would be worth it to buy a sheet of material directly from them, and then cut out the size you need. I don't know if EMS and Moxtek also supply mylar for people needing that type of window. If anyone else has used the ProLINE 20's, you might add your comments. It would be good to verify my idea that they yield superior count rates as well as hear if they mess up any type of analysis which we have not yet done here. Some folks might want to switch even if their present windows are OK (DON'T DO THIS UNTIL SOMEONE ELSE CONFIRMS MY IMPRESSION ABOUT COUNTS). Meantime, the crack in the rear window of my Mercedes roadster is still there. Have not figured a cheap way out of that one yet. The weather in El Paso is grand.

Has anyone actually ever tried to clean their sx's diodes, by any method? As for cleaning the flow counters in a mixture of acetone and freon, is one to avoid the use of an ultrasonic cleaner?

The dots are on all of them. I thought that maybe they might be contamination spots - but I went to an area that we'd never looked at, and they were there too. I did a 0.5 micron step 512 mapping at 20 ms -- they were there I did a 2 micron step 1024 mapping at 75 ms -- they were there One thing I noticed at the 75 ms mapping, that on the Sony, you see the stage x coordinate updated every 12-13 microns. Interestingly, there are about 85 spots across the image, which for 2048 microns, means one per 24 microns -- which is exactly double the reading on the Sony. Could the stage be NOT moving linearly? Speeding up, then stopping, speeding up, then stopping???... But this is unlikely, since they are not consistent, as you move down in Y.....they have the same frequency in that direction too, so I don't think that explanation is it....but rather something with the way the video is acting...

When I interrupt the CIAP scan, (ie vs1 aux), it both changes to CL and goes into some scanning mode -- so I have to add a mode fix.

Have you EVER seen a superimposed grid of spots on any CIAP images? Can you get CL in either SE, BSE or ABS?? Can you do it only if M1 is selected?

Main problem was a leaky window in a low pressure spectro. The problem was masked because the return P-10 line from that spectro (the line that feeds the bubbler) had a big leak at the fitting on the outside of the spectro. As a result turning off the P-10 did not cause reverse bubbling, instead air was sucked in through the leaky fitting. One thing that should have lead me to the problem earlier was that the regulator for the leaky spectro was at a pressure significantly higher than zero. I finally traced the leak to the spectro by turning off the regulators to all the spectros, then watching how fast each individual spectro would drain the gas from the tank regulator with the P-10 tank itself shut off. So I guess the moral is that even leaks in the return lines can cause or mask problems. From the P-10 usages that everyone sent I would suggest that anyone who gets less than three or so months from a standard sized P-10 bottle check all the brass fittings between the regulators and spectros, especially those on return lines.

All stage mapped CIAP images have superimposed a regular grid of dots (bright or dark, depending upon your perspective). For example, on a 512 by 512 image, with 0.5 um 'stage steps', the pattern is 10 by 10 dots. On a 1012 by 1012 image, with 2 um 'steps', the pattern is 40 by 40 dots. These appear on BSE, ABS, CL and SE images. If the desired image has a good contrast at low gain the dots are difficult to see. But particularly for CL images where the gain is cranked up to max, the images are unusable. (There are no such dots in beam scan CIAP mode.) Has anyone else out there ever seen this phenomenon? (Perhaps try acquiring a stage mapped CIAP image with the gain at 250 and see if you get the dots). 2. How many others out there do CL imaging? We are attempting to do CL mapping on large (mm) size areas, and are really ticked off that Cameca's software does not allow stage mapped CL imaging...you can choose SE, BSE and ABS...but to get CL you have to "trick" the machine by setting up for one of the above (we have only been able to get this to work for original settings of BSE or ABS, not SE as apparently some users can utilize). If you do CL stage mapping, please send me your specific settings in the CIAP window (ie. M1/M2, VS1/VS2, signal) thanks john John Fournelle Electron Microprobe Lab Internet:johnf@geology.wisc.edu Dept of Geology & Geophysics Office: (608) 262-7964 University of Wisconsin Lab: (608) 265-4798 1215 West Dayton Street Fax: (608) 262-0693 Madison, WI 53706 Amateur radio: WA3BTA/9 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

I have not seen anything quite like it, but I do recall a long time ago seeing some weird effect when stage scanning with X-ray images. Occasional pixels would pick up anomalously high counts which were digitally related. I can't recall now exactly what the pattern was, and it was often difficult to even know if it was happening, but it was there for sure. Then it was cured after our technician Edgar Chavez rebuilt the stage. I cannot remember the details now, but there was an unexplained digital interference from the stage movement getting into the image. It only happened when there was a signal - i.e. if you made a scan without the beam switched on, it was never there. Have you tried that? Do a CL scan with no beam. If as you say, the interference is more noticeable with lower signals, logically one should expect it to be there when there is no signal at all. That might just give you a clue to where it is coming from. Good luck!

Neil brought a level of technical competence and professionalism to this position which will be hard to duplicate, and we will miss working with him. I have just received permission from the Dean to search for Neil's replacement. Basically, we are searching for a PhD in Geological Sciences (or related area) with extensive microprobe experience, and with a good background in laboratory instrumentation (electronics, vacuum systems, etc). Appointment would be as a Research Assistant Professor with 11 months salary. Primary responsibilities include microprobe operation, calibration, and maintenence. The successful candidate would be encouraged to pursue external funding for their own research projects, as well as assist in other research projects. A certain amount of service work for other departments or commercial accounts is also expected. Because the job will require working smoothly with a variety of people from different disciplines, good inter-personal skills are essential. Highly-qualified candidates with Master's degrees will also be condsidered for appointment as Staff ("classified employee"). Appointments at this level are considered to be more service-oriented than a PhD-level appointment. We have just been funded by NSF to upgrade our instrument's computer operating system and software (we are now using the original DEC configuration). The new microprobe technician will be expected to take a leading role in making this transition smooth and successful (note: we have not yet decided which upgrade path we will take; if we go with the Cameca upgrade, UNIX experience is a definite plus). The position is available now, and I plan to fill it as soon as I can identify a highly qualified applicant. Please send resumes to me at the address below, or by email. If you know anyone that you believe is qualified for this position, please give them a copy of this posting and ask them to apply ASAP. A "formal" job description follows.

This is one of the lower vapor pressure hydrocarbon oils, and has general characteristics similar to those of the Santovac-5 and Convalex-10 polyphenyl ether oils. Before deciding whether or not it can be used in your pump, however, it would be necessary to know what oil you are presently using, the volume of oil needed for your pump, the pump wattage, etc. In the end, it would probably be safest to consult with Alcatel and JEOL on this matter.

It was stable most times. With the SX-50, we simply have not worried about it. However, I have noticed that if you work below 10 nA, you will get the extra significant figure to the right of the decimal. So if you can work at low currents, you might try that. When I have watched the meter carefully, I had the impression that the current value was rounded rather than truncated because it would sometimes roll back and forth between two numbers. Good luck and please let us know if you solve this. I sure someone in France could answer this question easily. Mike Geology and Geophysics Dept.

Several years ago, with older versions of the Stage/Beam Acquisition program, the z-correction would work in the y direction on our probe, but not in the x direction. However, it never attempted to adjust focus at the end of an x scan line like yours is doing. (When you say that it takes 7 seconds to adjust z at the end of each line, do you mean that it throws in the autofocus aperture and goes through a full autofocus routine?!!) We're presently using ver. 1.6 of the Stage/Beam Acquisition program, and all is well. The z axis adjusts itself continuously and correctly during each x scan line, and takes no extra time doing so. It also correctly apportions any correction in the y direction. Is this a problem which has suddenly surfaced after a period of time when the z-correction was working correctly, or is this the first time that you've had occasion to use the z-correction option? If it's the latter, and if you're using a different version of Stage/Beam Acquisition than 1.6,I'd be suspicious that the Cameca programmers may have started with an uncorrected version of source code when they updated the application for your machine. Good luck, and let me know if I can run any tests on our sx50 to try to help you pin down the problem.

The computer is a PDP1153. I have spent some time making modifications to the FORTRAN programming. One of the things that is bothering us in the very poor deadtime performance and to that end I made a small utility to collect data that can be used to plot count stability and linearity. The utility includes a function that reads the SEM variable CURR that you refer to, and yes indeed it is absorbed current. I do not know of a way to display absorbed current in a local window with an adequate number of significant figures. The software fix however does the job quite well. Are you set up to compile FORTRAN source on your system? Is it possible to run a task on the SUN that has been compiled on my PDP1153? I am willing to provide source code or compiled tasks. They could be uploaded to our internet server for you to collect via ftp. This would require that you have the capability of transferring them to your system (KERMIT?). Alternatively they could be mailed on FILES11 formatted diskette. Gordon Pringle From ???@???

The pulse pileup rejection circuitry cannot separate these x-rays, and they are processed as one pulse that is equal to the sum of the energies of the individual pulses. I suppose that your suggestion that the peak you observe is an L-alpha sum peak is therefore possible, but are you sure you don't have aluminum present? I would do a couple of things to check this; 1) Collect a "blank" spectrum of the matrix and see if you get a peak at 1.49 keV. If you do, you either have some aluminum in the matrix, or you may be getting stray x-rays from your detector collimator. If the latter is the case, you can slip the collimator off the end of the detector and coat the inside surfaces with carbon dag to eliminate it. 2) Simply lower your count rate by reducing your accelerating voltage to about 5 keV and check it again. Since the optimal excitation energy for the aluminum K-Alpha peak is fairly low, you will still see a peak at 1.49 if aluminum is present.

You should also see an Fe L-alpha peak if you are seeing a sum peak for Fe L-alpha, *unless* the lower level discriminator on your EDS system is set so high as to cut off low energy lines. If you suspect that the detector window is absorbing the Fe L-alpha lines, that detector would still absorb the two photons arriving simultaneously to create a sum peak, since each photon still only has the energy of the Fe L-alpha x-ray line. Lowering the accelerating voltage below the critical excitation voltage for Fe K-alpha does not necessarily eliminate the possibility of a Fe L-alpha sum peak since the Fe L-alpha line will still be generated. The best way to decide if it is a Fe L-alpha sum peak or not is to lower the x-ray count rate to reduce the incidence of two photons arriving at the same time. A simple tweaking of the beam current using a condensor lens control will do this. (Of course an even better method would be to make the observations with a wavelength dispersive spectrometer where sum peaks are not a problem.)

John, Here's the whole text of the email I got from Paul Carpenter. Hope you find it informative, as I did. Regards, AB __________Begin included text_____________ Be measurement is not easy. I use a Mo4C LDEB crystal (I think the d-spacing is about 149 A). The emitted intensity of Be Ka from BeO is only 3% that emitted from Be metal, and the emitted intensity from beryl and chrysoberyl is about 0.01% that of Be metal. So trying to analyze a major element concentration of Be in a matrix containing O, Si, and Al is like trying to analyze a trace element in other systems. The situation is a strong function of accelerating voltage used, since this determines the depth distribution of x-ray generation and emission. I have found that there is a significant increase in the emission of Be Ka at 5 KV compared to 10 and 15 KV. (By the way the emitted intensity of Be Ka from Be metal is again only a fraction of the generated intensity, so there is a large absorption effect; this also means that you MUST use a standard as close to the sample in composition to minimize dependence on the relatively poorly known mass absorption coefficients -- there is also a shift in peak position and peak shape as a function of bonding environment). The pulse processor must be set carefully to discriminate the low voltage pulses from baseline noise. You are simply wasting your time to try and do any sort of quantitative work on unpolished particles -- the situation is bad enough on polished clean surfaces (and of course if you are doing analyses at 5 KV then the surface characteristics can really affect the results). Our probe is a double turbopump system, so we don't have oil contamination from diffusion pumps, and this makes a big difference when doing light element analysis. Just for comparison, in the emerald work that I have done, I used 10 KV and 300nA just to barely get some counts. The Be peak really needs to be scanned and the k-ratio integrated; a simple peak and background measurement won't suffice. I have loaded the WDS scans into the DTSA program in order to deconvolve them, but there needs to be more background region to get the digital filter going, and the peak is near the limit of the spectrometer, so basically no dice so far (and this is on our extended range spectrometer). There is a major increase in feasability for boron compared to beryllium by the way. So to finally answer your question, I don't think Be measurement is going to be useful to you. You will need to disriminate minerals based on (for example) Al and Si content and/or the Al/Si ratio. You could even calculate Be by difference in emeralds, since they are quite low in Li. It occurs to me that most natural emeralds contain Na and Mg which substitute for Al and are coupled to maintain charge balance. The content of these can be quite high, up to about 4 wt % as the oxide. I don't think any of the other Be minerals exhibits this degree of substitution, so you may just look for Na and Mg to find emeralds (and I'm telling you a bit of unpublished research here). It is the Colombian emeralds that are low in Na and Mg, so this method gets dicey when dealing with those emeralds. Just being able to use a polished grain mount (grains in epoxy) would make this much easier and more rigorous. You could recover the grains by dissolving in acetone or xylene. Well, good luck!

I do not believe, that CAMECA will change this task for the software, that we (SX-50 and SX51-users) use at the moment. I hope it will be different, when the Openwin-Software for SX50 will be available. For the moment I think, that you have to find your own solution for that problem. Maybe, you can try to find the place in the software, where the rest.tas is called. If you are able to edit the Source-Files, then you can replace the name 'rest.tas' by names like 'rest1.tas' and 'rest2.tas'. After compilation you should define some different tasks for resting according to your needs. (I am not sure, whether the sources of the software ask directly for the rest.tas). >It is aggrevating (not to mention stupid and not good for the filament) >when I am trying to do small CIAP maps, every time it is finished >(maybe every 30 minutes) to have to turn the heat back up from 150 to >saturation -- because that is the rest.tas you use for finishing up an >unattended (overnight) run, when desaturating the filament makes sense. > Why do you not modify your SX-Local Window. This is very easy and you can define some keys, that will create a very specific rest.tas. This task can be defined according to your needs. When you start your application, you just click on your key and the task will be written and saved (theoretically!!) . Another possibility is to write a longer task, that might be activated by a special key in the SX-Local window. This task could ask for your heat or for the hv, that should be activated after finishing the analysis. After answering the questions, the task could save your specific rest.tas. The best way to make the rest.tas absolutely useless, is to run the machine 24 hours a day and 7 days a week. That is our way of working. Therfore I never put too much attention to this rest.tas. Sorry for my bad english!

If you are using Sunview, then a simple solution which I use is to modify the file .sxlocal to include a button on the screen labelled "Load rest. tas". I don't leave rest.tas permanently loaded, but simply click on this button prior to running a long job.

I ran into a similar problem with uranium in zircons a year or two ago and solved it by giving my standard a new name. Apparently QView will treat a standard with an atomic symbol name as if it is100% of that element. For example, my Uranium standard was "U3" and I kept getting very wierd U numbers even though I had entered the correct elemental concentrations in the Stage window. By changing the name to URA3 it all fell into place. I had good luck with thorium in zircons (good agreement with SIMs data) using a synthetic (?) standard from John Smellie, England, with ~15.00 wt.% ThO2. I also used a synthetec U standard from the same fellow but found it to be inhomogeneous and SIMs data also incdicated some slight problem with U numbers. Peg Snow From ???@???

It could run the SX about 40 minutes on its own. Given that minute long outages happened daily it was a good investment. Never had problems that I knew about with it, or with an Oneac. But Stephan at one point mentioned that the Puerto Rico machine had shown signs of power surges and that the UPS by itself was not a good power filter. Don't know more than that, although the UPS manufacturer (whose name I forget) had lots of evidence that the UPS provided very smooth power. I never saw any signs of surges through it.

The problems occurred when building power returned after our all-to-frequent power failures, or when I turned the SX50 on after a normal shutdown. Stage and especially spectrometer initialization would not complete successfully until the drive boards were manually cleared. We installed a UPS and our problems are gone! We now keep running through short power outages and we have no problems when powering on the SX50. We enjoy the added benefit of a temperature/humidity safety cutout that will shut down the UPS before condensation forms on hi-voltage SX50 components (this is nice in Hawaii where air conditioning outages can cause major problems with condensation). The UPS system that we have is from: Controlled Power Company 1955 Stephenson Hwy. Troy, MI 48083 1-800-521-4792 Our model is item #HV105 with a power capability of 10.5 KVA. This unit can power our lab (microprobe, computers, printers) for about 20 minutes. In addition, the UPS system provides excellent spike/surge protection and noise filtering. The cost of this unit was $8752. The size of the UPS is about 21"W x 33"D x 45"H.

Who has some detailed experience with Sr in silicates? I am especially interested in Sr in feldspars. Of course the Sr-concentrations should be very low. Does anybody analyse Sr in silicates (less than 1000 ppm) by routine software from Cameca? If yes, how much is the influence of the satellite line of Si K-beta'? Does anybody do corrections for this interference? My experience is telling me, that the influence of this satellite line is to high to be ignored. It is appr. twice the BG of any other phase, that does not contain any Si. I verified this by step-scans. This is true even for selected PET-crystals with a very good spectral resolution. Measurements with the TAP are impossible, the PET should give better results. Where is the optimum position for the BG? How should I calibrate my Sr? How should I correct the interference with Si?

Donovan) To: Multiple recipients of list Subject: Re: Sr in silicates X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Status: RO This is a "typical" interference in WDS analysis of silicates. By this I mean about 0.1 to 0.2 % overlap. Obviously some kind of interference correction has to be performed for analyzing trace concentrations of Sr. Here is a reference and the intro to my paper on treating this problem. Contact me if you have additional questions. Donovan, J. J., Snyder, D. A. and Rivers, M. L. (1993) An Improved Interference Correction for Trace Element Analysis, Microbeam Analysis, 2, 23-28. INTRODUCTION Spectral interferences (also called peak overlaps) occur whenever the wavelength of the characteristic x-ray used for analysis is near to or coincides with the characteristic x-ray line of one or more matrix elements and can be a serious source of error in quantitative microanalysis. For energy-dispersive spectrometry, the relatively poor resolution of Si(Li) detectors can induce large spectral interferences and consequently considerable effort has been expended in addressing this problem (e.g., Fiori et al., 1981 and Myklebust et al. 1981). On the other hand, little attention has been paid to interferences in wavelength-dispersive spectrometry, possibly because of the inherently higher resolution of the technique. Nevertheless, there are many analytical situations in which an inaccurate interference correction can create large analytical errors, even for wavelength-dispersive spectrometry analysis. In this paper we present an improved algorithm for the quantitative treatment of interference corrections in wavelength-dispersive spectrometry x-ray microanalysis. We then show cases of trace element analysis where errors due to spectral interferences occur and demonstrate through analyses of standards that even in these worst cases, the correction recommended in this study successfully accounts for the spectral interference(s). The technique that we develop is an empirical one in which the interfering counts are estimated at the desired peak intensity wavelength and does not involve estimation of the entire background due to interferences. Such spectral processing techniques have been proposed and have been calibrated for specific instruments (e.g., Roeder, 1985). Although these techniques can provide adequate corrections, they are in general time-consuming to calibrate and are sensitive to details of machine configuration. We present an easily implemented, flexible correction scheme that is not sensitive to various machine configurations. john ==================================================================== =========== John J.

I tried to use that task but it gave up and froze the probe so that I needed to reset the instrument. To be honest, I started from that routine to build my own one. The difference between gun auto and my task is that mine is slower but it shows you how the coils are working by displaying a graph on the Sony monitor. And, if you toggle the faraday cup and you are on a cathodoluminescent sample you will see the travel of the beam superposed upon the graph. Funny ! MENU.TAS is small enough to be left in memory and can easily call larger routines. If necessary it can be expanded to accept new tasks or maybe another menu in order to class the functions in different catogories. I will be attentive to all remarks concerning the tasks and will try to adapt or improve the code if possible.

If there is a cost involved let me know and I'll try and reimburse you somehow. Regarding the preparation of the glass material I can tell you what we did for the basalt glass. For BCR-2G we melted the material at 1350 C for about four hours in a platinum crucible. We then poured the molten material onto a platinum sheet to cool. The molten mass was allowed to cool overnight and we then broke the "pancake" from the sheet. A couple of points, it took a lot of work to break BCR-2G from the platinum sheet and crucible. The glass sticks to the platinum surface when it cools slowly. In a separate test we quickly cooled a small platinum crucible (100ml) containing molten BCR-2G by running tap water over the outside. Doing this pops the glass off the container walls with very little sticking. The downside is that the glass material is more brittle than glass material which is cooled slowly. Preliminary tests we have done with the USGS glass standards produce similar results though we have to heat the material to 1400C to get a very very viscous melt. I hope this helps On Tue, 5 Mar 1996 johnf@geology.wisc.edu wrote: > Stephen: > > Thanks for the GS glasses!

I thought about this possibility some years before, when I installed my first SX in Karlsruhe (SX 404). According to my knowledge it is not possible to bent the LIF 220. The crystal will break. So there is no chance to get a LiF 220 as a Johann-crystal for the probe. a flat crystal does not give good count rate. Concerning the letter of Peter Michael I can tell you, that the real problem does not come from the Si-Kbeta. The real problem is a satellite line, that is directly under the Sr-La-line. This line can not be neglected for low concentrations. The software of CAMECA is giving the chance to do line interference corrections. Maybe you have a version of software, that can just correct one interference. The software is called "filovl" and there is a description in the handbook for Quanti-View. I myself got a version of this software, that can correct up to 7 interferences. I asked for this, when I got my maschine. Unfortunately I never had the chance to test that software, but I hope to do some work on REE in the near future. There I will need this software. My real problem is: Who actually analyzed Sr in silicates in low concentrations? How successful was that work? I was just looking for somebody, who eventually allready used this software for the Sr in Silicate problem. If nobody else did much especially on this topic, I think, I should start the work on my own. Peter Michael will not have any success by working with the Sr-Ka-Line. Even if the machine would be able to work at high voltages, he would get very much analytical problems. Imagine the depth of penetration of the beam and the depth of information of Sr-Ka coming from the sample. It will be very high. You will analyze a completely different volume for Al, Si and Na on one side and for Sr on the other side. Additionally the matrix correction will not work at all for this arrangement. So forget about this method for the measurement of Sr. At the moment I do not have time to follow this problem, but when I will have results, I will tell to everybody, how to solve this problem.

We also had trouble when starting up after maintenance or power fails. We measured the SX power supply voltage (nominally 220V), which seemed a bit low (213V with the pumps running, 218V with the pumps SUSPended), and we noticed that when the rotary pumps started (together), there was a significant instantaneous voltage drop to circa 190V. My colleague, Terry Harrison, has powered the rotary pumps from a normal wall power outlet, separate from the SX-50 conditioned power supply. The SX still controls the pumps, as the normal pump power is used to switch two additional relays which turn the pumps on and off. We have had significantly less trouble with the SX on power-up since we have powered the pumps separately in 1992. I presume that any spikes and dropouts etc generated while the pumps are starting, or stopping, are less likely to affect the SX when the pump power is not coming from the conditioner. I recommend running the pumps from non-stabilised power and keeping the conditioned power for the electronics. As we do not have a UPS, we do not have to decide if it would be better to have the pumps on the UPS, and risk the spikes and voltage drop on startup. Another strategy would be to put a delay on one of the rotary pumps, so they start one at a time, rather than both at once. We have separate switches on ours, so we can do this, but it has not proved necessary with the separate mains power. We also power the control computer from the lab mains, but this is to allow us to use it while the SX is off for maintenance etc. Regards, Bruce Robinson --------------------------------------------------------------------- | Bruce Robinson |e-mail: B.Robinson@per.DEM.CSIRO.AU | | Electron Beam Laboratory | ,-_|\ | | CSIRO, Exploration and Mining |fax 61 9 387 6046 /CSIRO\ | | P.O.

It seems to happen relatively frequently during/after power-fails. We often find that one of the two thin separation windows is blown completely, when we turn the probe back on. When we turn the SX power off deliberately (using SX>HALT) we do not have this problem. Does anyone know why this happens, and what can be done to minimise the risk. Initially, we used to replace separation windows when they developed small holes which showed up as "argon instability" where the ion pump has rythmical rapid pressure rises. [This has been largely or partially overcome by the use of bimetallic elements (Ti/Ta) in the newer ion pumps. These are more tolerant to argon] Over the last few years, we seem to be blowing windows before they can develop pinholes. I do not know what has changed.

There was no mechanical problem that could be seen and in fact after a "tstw z" the position would reproduce perfectly again! However, it seems to me that the stage accelerates just too fast for it's own good. I can only imagine that this will get worse in time. Right now the stage reproduces perfectly to about .5 to 1 micron in X, Y and Z without a backlash correction, but I wonder what the reproducibility will be after 100,000 miles? Anyone checked their stage lately? Anyway, I just wonder if anyone knows of a way to slow down the SX-51 stage acceleration and/or speed to something a little more gentle.

Christian Haussaire, (Cameca France engineer) who installed our SX50, advises us to equip our probe with such instrument, mainly in order to detect vacuum leaks. With the remainder of our budget we have bought the MINITORR a gas analyser from VG Instruments. The system uses a standard quadrupole fitted with an electron impact source, a mass filter, a faraday detector and a RF generator which gives a 1-100 AMU mass range. This analyser head is mounted on the probe just above the transmitted light module on the left side of the SX50. A control electronics unit (3U high for mounting in a 19" rack) and an ISA PC board with the VG software package completes the configuration. We paid less than $ 7000 for the compete set-up. The only thing we supplied was an old AT compatible (640 Kbyte RAM, EGA/VGA graphic card). The maximum operating pressure is 1*10-4 mbar and the minimum detectable partial pressure is <= 5*10-11 mbar. However, we have had no leaks since the instrument was installed so its has not been fully tested. I have only use it to record some mass spectra which may later be useful for reference. I have not yet found time to experiment with it during probe analysis. I think it would certainly be preferable to share such a device between several labs rather than to be the sole owner of an instrument which is rarely used.

Unfortunately, I have not been able to do any probe work here yet. There is no technician to it is very difficult to learn the ropes. I am thinking about using a probe at another school, at least until things here are in order. Do you know where there is another SX50 nearby, say within 200 mile from here?

I know that >others have observed this as well but has anyone come up with an >explanation ? Yes, the microprobe analysis of garnets is problematic. Actually, it is silicate minerals of the Fe-Mg solid solution series in general that share this. Here is a short summary of my understanding of the problem: 1. It is primarily the absorption correction component of the ZAF algorithms that is responsible for over-correcting for x-ray absorption thus leading typically to high totals in the analysis (i.e. for garnets 101-102, and for olivines more like 101% in the total). Here I am assuming that end member oxide standards have been used (SiO2 for Si, MgO for Mg, and Fe2O3 for Fe, for example). So when one uses these standards, the analysis of a garnet or olivine yields a high total. The culprit may be that the mass absorption coefficients are in error for Mg (in particular), but also Si and Fe; these erroneous values lead us to the high totals due to overcorrection using a "faulty" mac. John Donovan at Berkeley drew my attention to this, by the way. The problem in general is that we cannot simply adjust the mac values to suit our needs in a particular compositional system because we may not observe the same problem in a different system. I don't remember the particulars, but it is also known that some factors in the fluorescence algorithms were originally fudged to work for metals (stainless steel), and that this optimization does not hold for silicate systems. So there are problems in several components of typical ZAF correction schemes and the parameters they use. Both ZAF and Phi-rho-z schemes use macs for absorption correction, by the way. 2. One really needs to use a standard as close in composition to the sample to be analysed when dealing with Fe-Mg garnets and olivines. I get good results for olivines using fayalite for Fe and an Fo90 olivine for Mg and Si when analyzing olivines that are in the Fo70-90 range. Of course all Fe can safely be assumed to be Fe2+ in these systems (but Fe3+ in olivines is not unknown). Garnets are a different story. I still observe high totals when using only garnet standards to analyze garnet samples. This again points to mac problems, but why we have success with olivines but not garnets is an unknown. Garnets are fairly dense and so one wonders about density terms in the equations; however, these terms cancel when the k-ratio is calculated. Really well characterized end-member garnets can be hard to find (like a pure almandine, for example). I will just mention that even though the garnet stoichiometry seems straightforward, that I have observed fluorine up to several thousand ppm in grossulars, and have been told about hydrogrossular component as well. It is possible, then, that the typical wet chemical analyses of our standard grossulars are incomplete. Fe is present as both Fe2+ and Fe3+, but one must be careful about making charge-balance vs. stoichiometric assumtions to calculate Fe2/Fe3. 3. Calculation of oxygen by stoichiometry works pretty well. You should try analyzing garnets for oxygen sometime (using garnet standards, for example grossular), and you will see that the totals are *really* bad as a result, compared to oxygen by stoichiometry. This points to the problems in analyzing oxygen in general. 4. Note that garnets can exhibit chemical zoning, but that this zoning results in the same average atomic number across this zoning due to coupled substitution, so that backscattered-electron imaging is not as successful at elucidating inhomogeneity as in other systems. This means that the homogeneity of a garnet standard (natural material) is suspect until verified by mapping or linescans. And that is just what came to mind while I sat here for a few minutes!

The problems with high totals in the Si-Mg-Fe system seem to be caused by a bad mass absorption coefficient utilized by most programs of Mg Ka absorbed by Fe. Most software I have seen use a value tabulated (but not measured) by Heinrich. This use of Heinrich's tabulation is apparently part of the the cause of high totals (when extrapolating from pure oxide or end-member compositions) for many minerals, especially those with high Mg-Fe concentrations, such olivine and garnets. Please note the following values (soft x-ray) quoted from Heinrich and Henke : Heinrich Henke (1982) Mg Ka in Si 802 859 Mg Ka in Fe 6121 5250 Si Ka in Mg 2825 2902 Si Ka in Fe 2502 2305 As you can see there is about 20% difference in the mass absorption coefficients for Mg ka in Fe, although the others are reasonably close. This difference will have a significant effect on the quantitative analysis (about 1 % or so). I have integrated the Henke value into my software as a default table and used pure end-member olivines as standards for garnet analyses and have not seen problems with high totals. There may be more going on here than just a bad MAC or two, but since this is the largest correction we make to our data, it's worth looking at first. john ==================================================================== =========== John J.

I have got serious problems with the motor assembly of that spectro. The spectro was installed about one year ago and after about 8 month one of the gears driving the spectrometer by the motor was completely eroded. I got a lot of dust close to the motor, coming from the smallest gear, which is made of brass. We had to exchange the complete motor assembly. We thought that this was a problem of the motor assembly, but now - after exchange - I found that the same is going to happen with the new motor assembly. We exchanged everything, including the motor, but the effect is exactly the same. It is just a question of time, when this gear will be completely eroded. My question to all of you: Does anybody else, who uses an extended spectro, find the same problems with this spectro? Does anybody else have the same problem on a normal spectro? I am lucky to be under warranty, but this may not always be the case. This will be expensive when the warranty is over!! One more thing: My present SX (Heidelberg) and my former SX (Karlsruhe) are running day and night. This means, that the motors of the spectrometers are continuously working 24 hours a day and 7 days a week. More than 50% of the time they are running in automatic mode. From time to time the spectro-motors are out of function. About 2 or three times a year I have to exchange one of the motors. As the motors are rather expensive, I am not very pleased about this. I would like to know from all of you, whether somebody has had similar problems with the motors of the spectro - at least from time to time. Who has had problems and who has had no problems at all?

A few years ago we having problems with contamination (Silicon) of samples prepared for EMPA. After cleaning everything we could think of, the silicon peak was still showing up on every one of our samples. At the time, my supervisor had a post-doc with extremely big hair who was heavily involved in EMPA and thus came in contact with all of our equipment. My boss began to suspect that her hair might be the source of contamination (her hair was always all over the place!) and tried to come up with a sensitive way to ask her fellow for a hair sample!! After feigning indignance, she sacrificed a few locks for the betterment of science. In this case we just soaked her hair in a 50/50 EtOH/water mix and placed a droplet of this on a carbon coated grid, waited 'til it dried and then checked it under the beam. It turned out that her hair was not the source of Si contamination, but we all had fun with it... Cheers, Russ From ???@???

It seemed to hold up well under a 10kV beam. This was for imaging, so was Au/Pd coated, however. Carbon-coating will be more interesting, but should still work. Since your person wants heavy metals, it might be worthwhile using low kVs and going for M-lines.

I have not done hair personally but it crops up in forensic science talks I attend. EDX is not normally used owing to the rather small amounts of heavy metal usually present. (You could ash the hair but in forensic science they usually want to look at application of heavy metals over a time period corressponding to different positions along the hair shaft). At the metropolitan police forensic lab in London they use a beam of X-rays and collect the signal with an ordinary EDX detecter eg arsenic poisoning. I have heard of labs which use an ion beam to irradiate the sample but do not know any details eg Napoleon's hair and arsenic. Hair will stand up to the electron beam without any problems.

In my former life at the University of Louisville before the Analytical Electron Microscopy Laboratory was closed and dismantled, I did the analysis of former President Zacheray Taylor's hair for arsenic. This was using an ISI-SS60 SEM equipped with EDAX. We obtained EDS spectra of uncoated and carbon coated hairs, particularly the "root" end using various stage parameters and levels of KV. Even hundred plus year old hair holds up well under the electron beam. Photos would have been even better if gold coated. Three separate laboratories got similar results, including that using Neutron Activation. No arsenic. Also, when groups of law students came over for the "Technology" course, instead of looking at fly's eyes, we had some of them donate hairs and we examined them with the SEM and EDAX. It seemed to be an exciting learning experience for them to see the differences in their very own samples. But this probably doesn't answer your question... Kind regards, Beverly From ???@???

Proton microprobe analysis was used to explore the relationship between changes in hair elemental composition and received dose. Due to significant variations in elemental concentrations among different hairs and non-uniform elemental radial distribution, a relationship between received dose and elemental concentrations could not be confirmed. However, most of the elements studied showed an increase in concentration after the irradiation period.

Depth-profiling studies have revealed differences between the outer (cuticle) and inner (cortex) regions of human hair fibers with respect to the molecular orientation and chemical composition of the constituent proteins. Raman microprobe measurements are applied to the identification and distribution analysis of textile auxiliaries on wool fibers. The advantages and utility of the Raman microprobe technique for investigating single textile fibers are also discussed.

If you have enough material (hair, that is) it seems that XRF is a good method. You could simply see what elements generate peaks, and then set up for quantitative analysis. I suppose you could actually chop up the hair samples to make a pressed XRF disk for quant analysis... If you only have a few hairs and they must be analyzed as is, then EPMA is going to be tough. You could try micro-XRF using a Mo thin foil mounted above the sample; same comments as above for bulk XRF. Paul +------------------------------------------------------------+ | Paul K.

Try getting your safety officer to conduct an experiment: 1. Hold out hand, 2. Pour a small volume of liquid N2 over hand 3. Now the interesting bit - put on a glove, and pour the same quantity of liquid N2 into glove. 4. Phone for ambulance. The point is that a brief contact causes no problems, but if the contact is continued you get a nasty burn. Gloves, goggles, masks (and shoes) are actualy more dangerous when handling liquid N2 than sandles and no protection. And clothes are actually more dangerous than being naked. Get the safety officer to experiment. With a little persuasion you can probably convince the safety officer that when handling liquid N2, everbody should be naked. More seriously, bureaucrats, administrators and the inexperienced should talk to somebody who has real knowledge. -------------------------------------------------------------- Dr. Larry Stoter Technesis 17, Rocks Park Road, Uckfield, E.

Any good safety manual for cryogenic gases specifically recommends sandals, and *against* shoes, gloves, and the like. The reason is the Leidenfrost effect. The LN2 droplets flash-evaporate when they hit bare skin, producing an insulating layer of gas, and prevents freezing damage. Assuming it's a quick spill, and not continous contact. Shoes, glove (including asbestos gloves), and any other clothing that confines the LN2, and cold gas *will* cause freezing. A face shield is a good measure, byt the gloves and any other similar regs are dangerous.

The closest I ever came to danger was when an associate put some in a nalgene bottle and closed the top, resulting in a frozen plastic flask going "POP". We did stunts along the lines of freezing the contents of our associates lunch pails, shattering a fish (boy was that an ultimately smelly mistake !), and once when we froze a rubber tube in the neck of a dewar by mistake, we had to empty the entire 50 liters into a trash container. Consider the heat of evaporation, compare it to the heat of condensation of steam, and think how many burns YOU personally know of from that source vs. from LN2. I am repelled at the lack of savy and the excess of fear instilled by the law ("profession") regarding such pseudo threats as LN2. The presumptive (and ignorant) reaction is irrational, but accfording to the same principles, TWO safety officers should come in the box containing each microwave oven, a gun should bear a judge attached, and an auto, a member of the supreme court, or a receipt for $1000 from your favorite lobbyist. Remember, not only can the law be bought, It's really CHEAP ! !!!!!! Good luck. Just act normal.

Donovan) To: Multiple recipients of list Subject: Deadtime and "DTIM" X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Dear SX users, I have wondered about the proper setting of the "DTIM" parameter on the SX dedicated PHA display. Apparently, according to Sam Pindrys, this is better refered to as a "recovery time" parameter rather than a "dead time" parameter, since it's value is the time after a pulse is counted, that no other pulses are accepted by the system. As far as I can tell, it is primarily used to prevent double voltage pulses that could occur when two pulses arrive at the same time. Of course the dead time correction still needs to be performed as is traditionally done in software. I measured the deadtimes on my SX with the "DTIM" set to 0 and and 3 and this is the results in micro-seconds for Ti Ka at 15 KeV in Ti metal : #1 #2 #3 #4 #5 PET LiF LiF ADP PET DTIM=0 2.5 2.1 2.2 3.4 2.5 DTIM=3 3.5 3.3 3.4 4.6 3.5 These data were acquired for 10 different beam currents from 10 to 200 nA for 5 points at each beam current counting 60 sec per point. The data was re-calculated using Paul Carpenter's "excellent" Excel spreadsheet for deadtime fitting. The typical measured sigma was .1 to .2 microseconds. It is important to note that a default DTIM of 3 causes the measured deadtime of the microprobe to be extended by about 30 - 40%. A cause for concern at high count rates. My question to other SX users is : what therefore is the proper setting for the DTIM parameter? I might speculate that to avoid at least the coincedence pulses it should be non-zero but small, maybe a value of 1. Too bad Cameca only allows integral values! john ==================================================================== =========== John J.

However, after removing the filament it appears to be OK, so I've reinstalled it and it continues to run. Has anyone else out there seen this problem? Is it a filament supply or gun voltage problem? By the way, it appears that my stage Z reproducibility problem may have been fixed by Sam Pindrys. Unlikely as it seems, the only thing he could find (after 2 other engineers and 2 days himself), was that the X and Z encoder cables were banded together tightly with a metal strap. He removed it and rearranged the cables. I'm still waiting for it to fail, but after a week of running it is still OK. john ==================================================================== =========== John J.

We have found that for the purpose of taking photos on the photo CRT, a DTIM of 30 gives much brighter dots than a setting of 20 (and certainly 2). Hope all is well with your new probe.

I also thought I remembered what the explanation was, but on checking my notes I find out that my recollections were were a bit garbled. The explanation I wrote down next to that occurrence is "message due to poor vacuum", which is not the kind of conclusion I would reach on my own and I am sure reflects input from Cameca (Edgar Chavez had not joined us, yet). If the above is correct, the link is probably in the vacuum logic. Another occurrence of a 'false' message is also worth reporting, in case there is still someone who has not encountered it. The message is "HV off" and it may occurr on performing a 'gun auto', or when trying to set a particular probe current value by a 'curr xx' (also giving "regulation not possible"). I was told that this happens when the 'heat' parameter has drifted down, with saturation, to a value close to 175 (I forget the exact value), and that it is due to a safety(?) feature in software. I cannot say I really understand the reason for this feature, but a way around it, at least for a little while, is to have the filament oversaturated. From ???@???

It turns out that a heat value of 180 or less will cause firmware to think there is a problem. An old filament at saturation can survive at lower heats if you are kind to it. In my case the result was a message "HV off" when GUN AUTO. So, I set the number that you get for the heat setting upwards. What was previously indicated as a heat of 180 is now about 200 on our system. By doing this an old filament will always saturate above the magic number of 180. I wonder if the same type of problem is happening to you possibly with respect to this or another of those relative values used in the system. I can give you info on how I re-set the heat value if you want to explore this possibility. Dave ................................................................

Ours was 15.8V to begin with. By re-setting to about 14V using R301, we now see what used to be a heat of about 180 as now about 200.

Hence, combined use is not possible. To solve the issue of having a separate M2 I simply purchased an additional NTSC/PAL monitor (about 750$ at the time). Since the monitor is 110v I also bought a small power conditioner which also isolates the instrument from this potential source of noise, as everything else is 220v via a 208v (isolated ground) line. The only reason I was sorry about not retaining the old monitors was that I would have happily donated them to labs in need.

The rocks I am investigating are gabbroic in composition. All the specimens contain olivine which has an mg# of 60 to 80. However, all the olivines in ppl show an unusual pleochroism in most cases resembling that of orthopyroxene (pink to green) in other cases it can be yellowish to bluish. DHZ (2nd ed.) reports that fayalite can be pleochroic, but the olivine crystals I have analysed are forsteritic in composition. Also the pleochoic scheme reported in DHZ is differnt from that I have observed. On the chemistry side most of the analyses of olivine grains carried out in energy dispersive mode tend to be slightly Si-deficient (0.97 to 0.99 a.p.f.u.). Can this anomalous chemistry be related to the optical features described above? Please keep in mind that these characteristics are very widespread in the rocks I am investigating.

For x-ray mapping, in the ANALOG mode, DTIM 20 does nothing to deadtime (no quantitation being done), but is a code to the machine to integrate (save) the counts collected over 20 microseconds, to give a brighter spot on the video monitor. He says you can run it up to 60 - the trade off is that the spots (~pixels) are further apart. For x-ray mapping, in the DIGITAL mode, DTIM is ignored And for quantitation... I'll let Andy himself explain how DTIM works for the deadtime correction. ================================== Second: Re SX50 users meeting in August There has been little response to the query I sent out regarding who will be attending the MAS meeting in August in Minneapolis (only 2 or 3 people responded). Apparently Cameca will have a several people at the Twin Cities MAS meeting, including Claude Conty. It would appear to be a good opportunity for (1) an organized technical session with the Cameca engineers present (we could define some topics, like the DTIM thing, the spurious? Filament messages, etc) and (2) speak as a unified group to Claude Conty about our concerns (which I think would revolve to a large part around Cameca France's unresponsiveness to software problems and bugs). I would think we would urge them to take part in our internet discussions. What do you say???

I, too, am mystified by the lack of CAMECA's presence in these on-line discussions. It would not be such a big deal for them to set up a Web page (www.cameca.com?) with product info, user support pages, etc.. And they could also get email at the same domain name for their personnel. Let's face it, Camecaxxx@aol.com ain't exactly a prestigious address. The prices for Internet Service Providers are coming down all the time. Heck, someone at CAMECA must have a spare Sun workstation around to act as the server. With a little work, an old DEC might even work. Of course, the easy and elegant solution is a Mac. ;-) I would think the benefits would be great for their company: *Rapid communications between the various CAMECA locations *Rapid response to user problems via email (lower long-distance phone $) *Quick notification of upgrades/updates/bugs to users *FTP site to download/upload software updates (we can dream, can't we?) *A presence on the Internet! I hope CAMECA realizes that most of us are friendly. We want CAMECA to prosper and succeed. We all have a lot invested in their products. But we get frustrated about communicating about day-to-day issues. Am I the only one tired of leaving phone messages when I have a quick service problem? If I could fire off an email (even to CAMECA France!) and get an answer within the same day, that would be useful for many, many situations. Just my $0.02 worth...

This is exactly why Cameca (Sam, are you listening?) should trash the oxygen leak and LN2 traps and simply put in a chilled freon baffle over the DP. This is mainly the source of carbon contamination in the microprobe after all. All this oxygen leak and chamber cold trapping hardware is working AFTER the oil is already in the probe!!! I can run for hours with a 100 nA beam on the same spot in my old SEMQ probe and get a carbon contamination signal increase less then 1 SD of the detection limit of carbon!!!! It would also be cheaper. The freon compressor we have has run (it's still running by the way) for 25 years with two replacements of the water dryer and a recharge during this entire period. These services were performed simply out of paranoia, the unit was working fine in both cases. So there are essentially no consumables except a little electricity. The baffle and compressor is less than $5K from Duniway Stockroom in California. I bet that this is less than the cost of the air leak and LN2 trap, especially if you add in the oxygen gas and liquid nitrogen costs. And it's easier, you never have to think about it. Just leave it on forever! The main difficulty that I see is space. There is just not much room above or below the DP. But I bet some clever engineering could take care of this. john ==================================================================== =========== John J.

I just taught my radiation sciences class about nuclear backscatter- ing (it was used as an analytical method on the moon, BTW), and the text-- Nuclear and Radiochemistry, Friedlander, et al., p430--states that the cross section is proportional to Z^2. Since it is a Coulomb scattering, and since e-e back scattering would have zero energy, I would expect electron back scattering to have the same Z-dependence as proton backscattering.

Just a few comments about the composition of the detector window material on EDS detectors. The mass absorption coefficients (mac) for Boron Ka radiation by different absorbing elements are (these values from table 14.3 of Goldstein et al): Absorber mac H 1,723 Be 69,937 B 2,861(?) C 5,945 N 10,118 O 15,774 So B Ka is strongly absorbed by a Be window on your EDS detector, and this (as you know) is the reason that B Ka cannot be detected with this normal window material. Note that carbon is fairly transparent to B Ka, either as an EDS window material via a diamond window, or as a conductive coating layer on your (nominally non-conductive) specimen. You should be able to detect B Ka on a carbon-coated sample and/or with a diamond window just fine; too thick a carbon coat will absorb just about anything, but comparatively it is not too bad. If you have a BN window, then the absorption is a little stronger than for the diamond window (average the macs for B and N). Even slightly worse is for the case of an ice layer (think of it as a layer of oxygen). Now if you have a too thick carbon coat, and a thick layer of ice on the detector crystal, and maybe you are using a thin Be window or a thicker BN window, then B Ka detection is going to be difficult. As mentioned before, reconditioning the EDS detector to get rid of the ice layer is mandatory before attempting to do light element work like this. Secondly, the pulse processor has to be optimized for processing low energy x-ray pulses -- if the discriminator is set too high you are filtering out all the low energy x-ray pulses, and if the time constant is set incorrectly you may not be getting the best throughput on the detector. Refer to the manuals at this point. Suffice to say that optimization of the detector should be done on a pure element (lump boron) before trying to look at lower levels in your samples. It was also pointed out by Chuck Garber: >There is just no better "standard" than a solid lump of pure boron! It >is inert and it won't be changed by the electron beam. Boric acid will >be unstable and as others pointed out, it will sublime causing all >kinds of other problems. Note however, from the mac values above, that B Ka is strongly absorbed by many materials (for example, the mac for B Ka by Silicon is 83,702), so you may see very strong absorption in a B-Si alloy (in fact, you may not observe a peak at all for lower concentrations of boron because it is absorbed entirely within the sample!). In this example, the absorption correction via the "A" part of the ZAF correction is very high for your sample, compared to your standard (assuming you used pure boron). The bottom line here is that you absolutely *must* use a standard that is as close as possible to your samples for good quantitative correction. Of course, the available boron standards are pure boron, boron nitride (which is typically polycrystalline and is not a good conductor; single crystal BN is much better but hard to find in pieces larger than a few microns), and numerous borosilicate glasses (which of course have the problem of absorption by silicon). For EDS work you probably have to use pure boron to avoid peak overlaps, but for WDS analysis things like BN can be used. The magnitude of the absorption correction is directly related to the accelerating voltage used, so if you can do analysis at 10 KV rather than 15 KV, you are better off. You can work at lower voltages (like your 5 KV setting), but the sample surface must be really clean, and you then get into problems where aspects of the correction algorithms are not really valid for this range of accelerating voltages. As a final note, it is relatively meaningless to look at EDS spectra of pure elements when shopping for an EDS system to do light element analysis. It is the performance on typical multi-element samples that really matters. For example, I was looking at the possibility of studying synthetic vs. natural emeralds (Be3Al2Si6O18) including inspection of the Be Ka peak by EDS. Even with a freshly reconditioned detector on *open window* mode, with the SEM probe current full up, no Be peak was observed. So Be measurement was just not meant to be on an EDS-SEM system. It turns out that even by WDS, using a Mo4C analyzing crystal (red-hot for Be and B), and the probe current full up on our microprobe (400 nA @ 10KV), and analyzing at low accelerating voltage, and a clean high vacuum turbo-pumped system, that Be in emerald is barely detectable (count times of up to an *hour* were used!). I'll just say that boron analysis is a walk in the park compared to beryllium analysis... Anyway, good luck! Paul Carpenter +----------------------------------------------------+ | Paul K.

When, in the SXLocal window or in an application program you enter for example HEAT 190, a certain routine will put that value to the input of the filament heating power supply. An hardware reading system will continuously verify the output and eventually asks its power module for adjustment in order to meet the required value (190). In case of problems, for fast response and to prevent the probe of important damages the power module will be switch off directly and only by hardware protections. This means that the uninformed reading system, which reads zero or a very low value, will send a flag to the monitoring software to display an error message. For IGUN, the philosophy is quite the same, if you enter IGUN 80, the hardware reading electronics will verify if its power module effectively gives 80. The monitoring software will display "anomaly of gun voltage" when, advertized by the reading system, the output is outside an admitted offset around the inputed value. Due to the poor linearity of the electronic feedback circuit which is often calibrated for 20 KV, this situation generally happens at voltages lower than 10 KV or/and with aged filaments. This means that the power supply can't achieve the demanded IGUN value while the high voltage and the beam current can easily be obtained for properly work.

CSV is comma-separated-value file format, logically similar to Tab delimited. I think tabs may get lost in e-mail and echoed as spaces, commas come through unscathed. I will send in a following message, as in-line text, a copy of our mid-Z (Fe metal) matrix). We have the interpolations for Al and Au matrices as well. I can't remember if I included them in the info I sent ages ago. One should be able to cut the text out, paste it as a separate file in a word-processor, save it as LIMTFE.CSV or whatever, and then read it straight into Excel or your favourite spreadsheet. I think there is a CSIRO logo which gets lost, but that's all. We often include the file in a standard e-mail. Of course, it can be sent as an attached document too. The .CSV file can be read by Macs, Lotus, Excel etc, and is good for simple numbers. We have a formal web site, Greg Hitchen, who is part our lab, spends most of his time on our network. He is getting our local Web going, so there will be something here when you want to refer to it. I am not sure of the address. Our WANUSX program is a good model for probe software. I have not seen Thiot's nor many others, so this is a bit biased. I know Thiot's is held in high regard. WANUSX is certainly more modular and better structured than Cameca's. It runs on the PDP-11 but could easily run on the Sun SX. It stores everything the way we like, and if the printer jams, the computer still records things, and all the obvious things. It is also designed to be easy to follow and modify. We have changed quite a few things to fine-tune it. When I have looked at Cameca's code, my head spins from looking at the spaghetti code. It is a long time since I looked seriously, but the structure (or lack of) appalled me. Other people's programs are harder to follow than your own, but we can follow Nick's code far more easily than Henoc's. We archive WANUSX user sessions, by number and name and project, we archive sample numbers (eg polished section number), and we archive point numbers. I think Nick had less levels of description. I like this way, and as we were paying at the time, he did it my way... When we put in a new point, the sample number remains the same unless it is updated. Hence, if one has 6-digit section idents, one only types it in once, and it continues till one moves to the next section. The point ident can be "altered olivine", or "Row 1 Grain 1 rim, repeat" or any other meaningful shorthand. I think we run to 24 characters or whatever. The text below is from our archive file. We have all 100,000 plus analyses on disk. We retrieve them in this form from the files which archive every successive 1,000. This one came from file DAT098.DAT. We retrieve a string of analyses eg I got all 98308 to 98317 (or several hundred). They come in this format. The three columns are % oxide or element, atom ratios, calculated to the number of oxygens requested and the elements as ppm, with < detn limit quoted if detected. The paper output has precision, ZAF factors, counts etc as well. Session 17(87) has user SJB, project WMC chromites and has analyses 98308 to 98317 ! this was read from our session record which is printed out every 100 sessions. We do not use this bit much, but it does have an index to go back if people have forgotten their analyses number, which is the prime retrieval key.

In this case, the lead peak must have moved, but the estimate is far too large (as the five points are only say 5-10 units apart, so it is an extrapolation error). The peak integration is both fault-tolerant and informative. It tells you the peak is moving, while at the same time collecting good data. The Mo peak must be correct, and the others are too low to estimate the peak position. The probe has not been very busy in the last couple of months, so we have not raised the total analysis count much. CSIRO-Trace The CSIRO-Trace run has just finished, a series of traverses across some iron ore, for Zr, Ti and P. There were 450 points, and the last trace analysis was no. 14,429. It seems Greg (GJH) has not been particularly informative when he described the project... We were doing 100 points or 50 points on each traverse. I am just going back to have a look at major elements (still using CSIRO-Trace) at 15 kV and 30 nA using the same XYZ coordinates. Our system can hold up to 1200 points at a time. The file below will also be stripped and input to Excel. This is part of TRC00629.DAT, that is the 629th CSIRO-Trace file. I think we have all 629 available!!!. I was doing a single 100 second count, then changed on this traverse to two cycles each of 100 seconds. The apparent conc and SD in PPM at 100 and 200 secs are recorded, the beam current (circa 450nA). The first count is from 100 seconds, the second is the running total from both. The raw counts are printed and displayed, (but not archived), so one can see what is going wrong. Problems are common at trace levels. I presume you know a lot of ways of getting the wrong answer. This was at 35kV. This took too long, and this morning, we went back to single cycle counting of 1 * 100 secs SX-TRACE low level analysis Version 7.26 (22-Feb-93) 22-APR-96 15:12:55 User: gjh Project: test Zr P Ti Sample: 16/8/10 A MFK Analysis: 14029 X:-10150 Y: -1545 Z:-413 Point : TR 2 MIDDLE 22-APR-96 19:06:39 1 100 449.625 21.

Nick's ZAF gives better answers on silicates than other things. I got the impression from John Armstrong when he was here last that some ZAF routines work better for metals, and some for oxides etc. We now can get a second opinion on the same data. It is a bit messy, as we have to create our own WANUSX method file, and a Cameca one, then port the data from one to another. WANUSX now writes K-ratios to a file for input to OFQANT, as I recall. I haven't run it in anger. Greg is the one who is closest to it. I think Cameca should redesign their system from the ground up. A sensible look would look at Thiot's, ours, Cameca's and others like Donovan's. He ported his old software to the SX, I presume. We can not imagine how people use Cameca's suite, but they do, and successfully. It is a bit embarrassing to admit we can hardly drive the French software. Our software is in the public domain, effectively. We thought of trying to sell it in 1988, but it became apparent that everyone is wedded to Cameca. At the time, it was a long way ahead, overlap factors, peak integration etc. As I did not design it (Nick is the architect), I can say it is very elegant, and fault-tolerant. I would like to get a few people in a room for a few days, and one could design a modern modular system. User interface, file structures, data requirements, options, conversion from old-to-new interfaces. With a good design, it should be easy for the new system to be implemented, and also retrofitted to all SX's, with the probable exception of the PDP-11 ones, which will have special space limitations which may not be worth bothering about. My impression of Camceca is that they have been fiddling with the user interface, but the file and structure is largely unchanged since RT-11 on the Camebax circa late 1970's. Perhaps I don't know much about it. We had long considered a public domain, machine independent system. WANUSX will run on the Microbeam, and the PDP-11 SX, and can easily be adapted for the Sun SX-50. I do not know how much different the SX-100 is, but my guess from a distance of 10s of thousands of kms is that the major change is the user interface and the structure is unchanged, or little changed. CSIRO-Trace and WANUSX are both designed to be machine independent (both computer and probe), as the libraries should take care of the probe-dependent things, and Fortran should take care of the computers. Move spectrometer and move stage are commands common to all probes. Files are common to all operating systems. We do use the CIPP large area mapping program, but use a satellite "remote-sensing" PC program to manipulate the images etc, ratio, background subtraction and so on, then into Windows to print etc. I hope this makes sense. It is late and I am trying to do several things at once. The probe is doing majors, but using CSIRO-Trace as it is quicker. I have graphed the traverses for Zr, P and Ti. The data are a bit random, but I don't think it is the probe's fault.

However, I think that the important point is that what I am experiencing is NOT what you are describing. I have repeatedly (5 times now) received a report of "filament out" with a new or relatively new filament at normal filament saturation (60 ma) and voltage (15 KeV) during normal operation. Sam Pindrys has had me check a test voltage that triggers this message and we did find it to be about 25% low. I adjusted it and am waiting to see if the problem continues. I will keep you informed. Meanwhile, my Z stage axis motion continues to be very reproducible since Sam Pindrys removed a metal strap that bundled the motor encoder cables together. The problem was evidently that X axis encoder counts were being picked up also by the Z axis causing the readout position to be correct but the actual focus to be off by a variable amount from 5 to 500 microns. Sam did admit that all other SX-51's have this metal band. Has anyone else had stage reproducibility problems??????? That is, the readout position is correct, but the position as determined by the focus or point of interest on a sample using the light optics is off.

Unfortunately, there's no easy fix for it. It's due to the reversal (at the factory, inside the assembly itself) of the 2 wires that control the "motor drive". Because of the very short play in the cable attached to the 4 pin female connector that plugs onto the Faraday cup assembly, one doesn't have the option of temporarily cutting and reversing those two wires there (blue and white). The best option is to insist that Cameca send you a correctly wired Faraday cup assembly. The only other option you have is to reverse those wires at the picoammeter board (schematic 29256287;about middle of volume 2). The blue wire (bleu, FC+) is normally connected to TP33, and the white wire (blanc, FC-) is normally on TP34. Reversing these should make this anomalous Faraday cage work normally.

Hulsebosch's PMMail v1.1 Subject: Re: how do you like WANU-SX software? Status: RO Hi John, We use the Trace routine from CSIRO for both trace element and volatile analysis. We're pretty happy with the software but use it only for special applications. One of the limitations is that there is no ZAF correction built in to the CSIRO routine. Also, it requires very manual setup (i.e., all peak positions and standard count rates must be manually determined using SX-Local then entered into the Trace routine). I would NOT advise replacing the Cameca software with Trace - it does not have the flexibility or ease-of-use necessary for day to day quantitative work. What is very nice about the Trace routine is the built in cyclic counting. You enter a counting time for one cycle, then let the analysis repeat cycles until the desired statistics are accumulated. The faraday is activated after each cycle for beam measurement. We have found that beam damage is dramatically reduce by interrupting the beam in a cyclic manner. For volatile analysis of basaltic glass we use 70-80 nA beam currents and 20 second cycles. After accumulating 200-300 seconds of counts we see less beam damage than when using a 30 nA beam for 100 seconds (without cyclic counting). The bottom line is that Trace is good for some specialized applications, but not for routine quantitative work. I have been looking into the SamX package and I think it is superior to Cameca's software. Also, the people at SamX seem very responsive to user suggestions and changing operating platforms (Windows & NT). The problem is cost - its pretty expensive! We will be making a computer upgrade soon and I am seriously considering the SamX package. I need to look into the package from John Donovan but I'm worried that his software may not be as evolved as SamX. I hope this info helps! I wish Cameca would get with the program. We're still using a SunView version of QuantiView and by the time Cameca releases their "imminent" upgrade, Solaris will be outdated! It looks like sticking with Cameca software dooms one to using outdated operating systems. From ???@???

I used this software last week and it has some "fully manual" aspects that make it unattractive for routine use. We have not used the file storage aspects of the program but have found it of great use especially for volative analyses of glasses. I was doing nepheline analyses for S and Cl last week (that was very minor amounts in this nonhydrous minerals). Thus, although the program is cheap, you get what you pay for. I think we may go with SAMx if we can swing the money. We have two more years of software free upgrades promised from Cameca but are they worth the wait? The software has improved but they have not made the corporate decision to make quality software for a modern operating system. Too bad. Good luck and keep us posted on your decision. cheers, Mike Garcia Geology and Geophysics Dept. University of Hawaii Honolulu, HI 96822 voice 808/956-6641 fax 956-2538 From ???@???

I have installed it in Tasmania, and Melbourne, but both were committed to Cameca's system, and we were talking $10K at the time!! so they did not proceed. These are both PDP-11 SXs, Nick Ware's lab at Canberra, Australian National University, Research School of Earth Sciences, still uses a slightly earlier and different version. I think he has done 300,000 analyses using the system. We only have done 100,000. We ported his version here in 1987, then modified it a little. Hence, there are two labs, our SX, and Nick's Microbeam. The main difference is in the low level library calls. We wrote WANUSX so it would run in Canberra, but Nick liked doing it his original way. His disk space was smaller, for instance. CSIRO-Trace has been installed on 7 or 8 SXs, nearly all Sun SXs. It would be interesting to port WANUSX to a Sun system. It should not be too hard. It would probably need some expertise at the target machine as well. CSIRO Trace was simpler and could be installed as a turn-key system. I suspect that the Sun version of WANUSX would have more problems, and would also lend itself to more fine-tuning to suit local needs, as we did here. One advantage of both WANUSX and CSIRO-Trace is that it opens the door to local programming. This is a technical advantage, and a psychological benefit. If you know you can fix the bug, it is easier to live with if one does not get round to fixing it. You can set the priorities. If one has to rely on Cameca, one feels powerless. I can feel that coming through all the time. Most people can speak Fortran. (I guess I am showing my age...) Yes, it would be possible to transport it. Yes, I would like to come to Madison. Yes, there would be some associated benefits. My guess is that it would take about a month. My guess is that CSIRO may come to the party, if fares and modest accomodation was paid at your end. We have partly taken a decision not to sell CSIRO-Trace so we keep our technological edge for our core business. [Does that sound like management-speak] I think this was a decision of convenience that I suggested, and this could be reversed, at least in restricted cases. I would have to brush up on Unix again. I am scheduled to do some programming soon, our Aus SX engineer, Graham Hutchinson. who is a quasi-freelance person has designed and built yet another optical microscope point location/transfer stage etc. Graham runs a consulting business Microbeam Services. He may be able to assist in the US by second-guessing Cameca, but he is pretty busy. I think he is on your list. [beamm@mail.enternet.com.au] [By the way, how does one get a copy of the user-list now. I presume one can read the MajorDomo manual...?] The microscope transfer system (Digimax) works on the PDP-11 SX at U-Melbourne and Graham wants to transfer it to a Sun SX. He has been making heavy weather of it, so I have offered to help. Our tame SX in Sydney which we used to port CSIRO-Trace has sprung a network problem. The Sun reboots spontaneously when it is on the network. This seems to disconcert the probe users for some reason, so Fred Scott has pulled the plug on the network. Hence, it is harder for us. I hope to port the Cameca F77 compiler here to our network Sun, but have not yet. Graham is scheduled to come here in May to do a service for us. It is a very long time since anyone has done this on our machine. Not since I burnt out the scan coils while building a better BSE detector. Development of the "converted BSE detector" stopped at that stage. It didn't seem to work as well as it should anyway. How was I meant to know that putting a bit of brass wire mesh just above the sample would drive the scan coils into destructive oscillation... Graham replaced the scan coils under warranty. Cameca have been quite good to us in a number of ways...That is another story.. We can actually port WANUSX to your machine down the network, and run it from here, for instance, so a lot of the development work can be done by remote control. [I assume your Sun is on Internet.?] For a couple of reasons, I think it is close to essential for me to come to install it. With CSIRO-Trace, we had it working in Sydney first. As we know CSIRO-Trace works, we can be assured that WANUSX will as well. There will no doubt be some annoying problems. More later when I ask Greg more about porting WANUSX. We have recently had a bit of a look at it when installing the PAP option, so it is fresher in our memory. The pulse of development was just when we got the probe. In retrospect, we get marks for bravery. We got the first SX in Australia, discarded its software and installed our own, and had it running OK within about three months of delivery. I am not sure I would be that brave now. It has had its advantages, though. The person who did most of the porting, Rob Walker, now works for Link (Oxford) in Boston. He is closer to you than to me now. He has done some work on Sun SXs. He wrote the Turbo rare phase search program which is available for the SX. He did some work at Imperial College, London, on a Camebax Micro and then came back here for a while, and wrote a version for us on the PDP-11/SX then ported it to the Sun-SX. Rob is a really good bloke. He can probably sell you a Link Spectre system to run the SX-51, if you are rich. Do you mean just WDX or WDX plus EDX?. The latter is harder, due to interfaces etc, and we don't know much about the PGT, if that is still what is being sold. We have never really used our WD/ED WANUSX. It has worked, but it was never used apart from tests, and now there is an interface problem of some sort. I think I side with the French who think EDX is not real probing, as Castaing did not invent it. We use ours semi-quant to see what the phase is. We are just slack really. It is a public holiday here, ANZAC day, to commemorate a momentous defeat at Gallipoli in WWI in Turkey. I just dropped in to see how the SX is going. It is doing another 450 points for Zr,P,Ti counting 2 *100 secs. It takes a long time. The SX has some terrible overheads, but perhaps the SX-51 is a bit better. The stability is a bit sus, as it has been running since 5pm yesterday, circa 31 hours, and the regulation at 450nA is taking some time each time we read the beam. I have decided to leave it rather than attempt to realign it and get it going again. I better go home. Thanks for the interest, very flattering.

In both cases there is a program you can use to do backward PAP calculation (some purists would say C->K is the forward calculation). Actually on both Operating Systems, this is the same FORTRAN program called OFQANT. This program can be ran from the usual binary (executable) directory (On DEC SET DEF 200,200, On SUN in a cmdtool go to the $SX50 directory). Before proceeding with this program you need to have a declaration done, a *.DEC file must exist. Therefore you just need to create one the usual way, but you don't need to go to any experimental description. Once you have created the DEC file you can then run the ofqant program ( DEC=RUN OFQANT, SUN=ofqant). The program will first prompt you for the declaration file & then for the type of calculation you want to do (AL to go from K->C or KR to go from C-> K). Depending on the mode you will have either to enter relative intensities or Weight fractions. Hope this help. If the bet was a dinner in Paris, I do know a few good places... Jean-Frangois.

Pouchou on the phone yesterday and asked the question. Jean-Louis said that when they came out with the PAP in 1985 they were first looking for a short name, very similar to ZAF. They wanted the name to be as international as possible and therefore decided to go with Pouchou And Pichoir. Personal & humorist comment: Actually there might be some French Ego evolved since the word "PAPe" in French means POPE. Talking about names, this remind me of a Slovak product from Telsa back in 1987/1988. This was a very nice portable SEM without chamber so that you can literally put the SEM column on any large piece of material. They did a relatively good job in Europe with this product which they called BS343, but when they went after the US market & for some reason, they decided to call the product "The Sucker". The US brochure was the funniest piece of material I ever read. If somebody still have a copy of this brochure I would love to get a copy. As you can expect, the Sucker didn't do too good in the US !!!! Jean-Frangois.

My suggestion is to perform your final, deformation removing step, on a soft cloth such as BUEHLER's MICROCLOTH(R) or MASTERTEX(R). Instead of 0.25micron diamond, use MASTERMET(R) final polishing suspension with light pressure to polish the gold surface. The ideal is to perform final polishing on a vibratory polisher such as BUEHLER's VIBROMET(R) 2. Recent years have seen a great change in vibratory polishing at BUEHLER. In the past, vibratory polishing was used sparingly by many people due to the rounding effects incurred. However, the VIBROMET(R) 2 has been changed to produce less of a vertical movement component, and to increase the horizontal component. This effectively eliminates the rounding effects which were the bane of vibratory polishing in the past. If you have any further questions regarding gold polishing or vibratory polishing, please don't hesitate to contact me (I will be out for the remainder of the week), or one of our other sample preparation laboratory experts by calling (800)BUEHLER [(800)283-4537].

What I can say about your question is that there had been thight relationship between CAMECA and the lab in BRGM (this is now over for a couple of years or so). In fact, the lab was a sort of showroom for CAMECA regarding the earth sciences. During this periode, the lab produced standards for CAMECA. All the minerals used as standards were natural samples, carefully separated and chemically analyzed (not with the probe, of course) to check their pureness and homogeneity. The issue is that nobody can, now, certify their quality since the procedure used is not available (this was done some 10 or 15 years ago). Pure elements, like metals, were bought from chemical companies, like Johnson Mattey or something. Concerning the reliability of these standards, I just can say that the lab has always used these standards with no problem. I hope I gave you the right answer to your question. Anyway, I am glad you created this SX-user group. Olivier From ???@???

I can tell you, it is not troublefree, either. Approximately a half of our non operational days come from that machine. First we filled the cooling system with tap water as recommended by Cameca and got after three months use a serius 'rust grud' problem. Then we asked Cameca what to do and they recommended us to use 50% glycol + 25 % distilled water + 25 % tap water. We also changed the vinyl hoses between the cooler and SX50 to ones made of copper. This stopped the rust formation which was caused by a pump with cast iron rotor housing, or by the vinyl hoses letting oxygen through to cooling water. The pump was changed this year. Because of the rusting problem the SX50 stopped several times because of stucked coolant filter. In the last annual service the cooling system was cleaned and the pipes of SX50 were blown with compressed air, which removed lots of 'rusty grud from SX 50'. Then the system was refilled with a mixture of glycol+tap water+distilled water again. After this operation the filter has been changed a couple times after the SX50 has stopped because of poor coolant circulation. I hope the Carrier now works some time without breaks! We have an off-line point logging system hooked to our Sun IPX two computer system. The other workstation is ment for optical point logging and optical image analysis. It has Leica DMRB polarizing microscope for reflected and transmitted light, a SONY CCD camera and a Marzhauser XYZ motorized 1 micron stage. The Marzhauser stage has a special holder for Cameca shuttle. The point logging pprogram is made in U.K. but it is sold by Cameca. Ours has been rewritten to SUN and also to Windows. We have not used it much, but it works and the precision of points after transformation calculations is around 10-20 microns. The stage program is made by Princeton Gamma Tech (PGT) and it is part of the IMIX software, which we use for both running EDS and image analysis. PGT has also Import Points program, which corresponds the British Point Logging program. Marzhauser is a nice stage but I would not recommend it today, because there is no autofocus program for it available. PGT has autofocus XYZ program to the LUDL stage made in USA. best regards, Kari.

They are reversible, commercially available, and come in a variety of sizes and wattages. sorry, I don't have a source. If you cool your sample with a larger LN2 system and you have a clean system, you should be able to cool and heat your sample with little condenstation problems. Don't cool down the sample until you are at your system's lowest pressure (probably less 10^- 6 Torr or better in new SEM's) YOu will probably get a slight increase with heating the cooled area and the pressure rise will depend on the length of time that hte sample was cooled. However, remember that the gun area with ion pumps are differentially pumped with respect to the specimen chamber. The conductance to the sample from the gun area is extermely low. Furthermore, the ion pumps handle water vapor very well. Just make sure that your filament is off and that you reheat it a little bit more carefully next time you bring it up.

This can be a very real problem for most electron microscopes. There are three things that can be done to control it; 1. Algal growth can be greatly retarded by excluding light from all parts of the cooling system. This involves using opaque tubing, and keeping the water reservoir in the water chiller covered with a light-tight cover at all times. 2. Further control can be achieved by using an algicide. The old standby is a product known as Chloramine-T, which is the sodium salt of N-chloro-p-toluenesulphonamide. This is available from most specialty chemical companies (e.g. Polysciences, Sigma, Aldrich), and is used at the level of about 1 gram per gallon of water in the cooling system (0.25 g/litre). 3. A filter should be installed on the intake to the water line to prevent algae and other solid materials from getting into the cooling lines of the lenses, etc. This filter must be cleaned, and preferably replaced, on a regular basis. ( Ref: Vacuum Methods in Electron Microscopy, by W. C. Bigelow, Portland Press, 1994, p. 216.) I have not had any experience with the product called Thermoclean DC; however, we have used the Chloramine-T stuff in our several systems here at the Univ. of Michigan for a number of years with very good success.

Spectrometer motor info as requested. Part number (printed on the motors) 28GD11 219E 404E2 We ordered some motors in January 1995 from the Australian agents. Price(each) January 1995 Quantity 1-4 Australian dollars $826 5 $692 Exchange rate then may have been about Aud 1.00 = USD 0.74 or so The motors are made by Portescap PEX Division 157, rue Jardiniere, CH-2301 La Chaux-de-Fonds 1 Switzerland Phone 41-39-1-26 61 11 Fax 41-39-256-594 Contact Marie-France Cattin if you need a name. The delivery time quoted in Australia is usually 8-10 weeks, but our order took about 6 months. The motors are made in batches, and if one just misses the next batch there can be a delay. It pays to have some in stock, and in Australia, we scrounge motors from other labs when we get caught short, and pay them back when the next batch arrives. With the large number of users, it may be possible to get a big batch made, at a larger quantity discount. We would like to join in for say 5 motors, if anyone is organising a purchase. We are concerned that the motors don't last very long. We have just replaced one today, so we are thinking of motors, and have just asked for a current quote. I was told today that our motors can come via Japan, but I think the last lot came straight from Switzerland. The US agent may perhaps have some in stock.??? We have used about 1 per year on a three spectrometer probe overall, but it seems the new ones are not lasting as long as the original ones. We have installed, on one spectrometer, the modification, now fitted to most probes, of a 40 mm inductor and a capacitor close to the motor. This has made that one motor run cold, while the others are quite hot to touch. However, we have lost two motors from that cold spectro and none from the others in the year or so the mod has been on that one spectro. There is also the "oscillations at rest" phenomenon about which I inquired a while ago. The motors often oscillate slowly when they are sitting still. There was some correspondence on the users net, but I have not done much, nor have I summarised the replies. I hope all is well in Ottawa and the rest of SX-land.

It blew a relay on a control board again so the engineer came to fit a heavy duty contactor in it's place. Well..... After he had fitted the part I ran up our Sx (being closed down in a nice and clean manner - I've learned the lessons :-) ) only to have the chiller blow up again as the Sx was initialising the spectrometers and stage. The X drive gave a bad result from it's test and none of the usual resetting operations ( front panel button reset, reset boards or shutting down the PSU's for 15 mins etc etc...) worked so I swapped the X for the Y boards and the problem remained at X so I surmised that the problem was at the stage mechanical end. Dropped the stage out and it was all the way over to the left. I managed to move it back nearer the middle manually but still TSTW X and ZERO X had no effect other than to make the gears move a tooth or two. Now XY and Z all give the depressing "end of test, bad result(s)" Any clues anyone? Robert McDonald Microprobe Lab Geology & Applied Geology dept Glasgow University Scotland UK From ???@???

I certainly echo the comments in your last paragraph. I feel the words "The first sense, in which pulse pile-up can be untangled, is no longer in the realm of theory." are rather overstating the case. Practical circuits to detect pulse pile-up have been available and present in equipment for over 20 years so this issue is hardly "in the realm of theory". The major advances in recent years have been in improved electronic detection of low energy x-ray events ( < 1 keV ) which reduces pile and gives better spectral fidelity in this low energy region. Now that high speed ADC's are available at reasonable cost, a digital electronic implementation is considerably more convenient and flexible than playing around with delay lines and complex time-variant analogue circuitry. Nevertheless, all electronic processors are faced with the same problem: the major component of noise at the detector head is inextricably linked with the photon signal before the signal is digitised. "Adaptive pulse shaping" has both benefits and disadvantages depending on the intended application but as far as I am aware, it cannot tell the electrons in the detector and FET when and where to move. I am also one of those commercial guys who wants everyone to buy an EDX system... I hope for all the right reasons.

I would like to hear from the source what they recommed for longer >life. I do support a pool of motors or at least lowwer cost from Cameca. I have seen servo oscillation on other instruments which are caused by improper tuning of the PID (proportional/integral/derivative) control loop. On my old probe these parameters could be adjusted in a configuration file but on the Cameca I would assume that these are burned into the ROM and hence not easily modified. I, myself, would like to slow down the motors (especially the stage), since there is no good reason to have them so fast, but I have been told by Sam P. that (at least) the speed and acceleration parameters require a new ROM, which I am badgering cameca for. But back to the oscillation problem; the cause is generally a "too tight" motor loop. On my old probe's servo system, the integral gain is increased to reduce the motor error and the derivative gain is increased to reduce oscillation. By judicious selection of these two parameters, the servo can be made to have close to zero error and no oscillation. However, the exact value of these parameters depends on several real-world constants such as the electrical and mechanical characteristics of the motor itself and the actual friction and mechanical load on the motor system. The company that manufactures the servos I use, has a very nice self tuning applet for this purpose. Using a different brand or type motor would be no problem assuming that the servo tuning loop parameters could be optimized specifically for it. john ==================================================================== =========== John J.

These compounds are stable and behave well under electron beam irradiation.

It is CsSi2AlO6. The analysis shows 30.0% Cs and 0.7%Rb as well as 1.3%Na and 0.1%K. In other words - all the alkali metals but only Cs in any reasonable amount. I doubt if it would be very much good as a standard for a major amount of Rb. The alkali metals are too reactive to mount as metals, which is the reason they are not in the SPI Supplies "44 Metals" mount. More information about these standards for microanalysis and prices can be found on our web site given below. Two other points: a) The "homogeneity" of this mineral is considered outstanding as determined both by ourselves and our customers, and b) we don't normally offer the mineral by itself, however I guess our arms could be twisted if that really was the only mineral you wanted (needed).

Staub, and I am working with the SX100 development group in Cameca France. I am grateful for having recently been admitted to your online users group. I would like to seize this opportunity to give a public answer to some interesting and critical questions that I received lastly from one of your founders members, Prof. M. Garcia of Hawaii University. I was first told to clarify some rumor according to which the next SX Cameca software versions would be delivered with an outdated operating system. Obviously, this rumor is pointless. The true story is the following: - The SX100 software has been working under the SUN/Solaris 1 for two years. - The SX100 software is now converted to the last Sun operating system Solaris 2.X and this combination is to be released for SX100 instruments by August 96. - We are definitely achieving the heavy tasks of adapting the new SX100 software to the SX50 instrument: first release in September 96. For safety purpose, it will first be delivered under the Solaris 1 operating system. - This last software version will be converted for SX50 instruments under Solaris 2.X: to be delivered by December 96. The second critical question raised by Prof. Garcia concerns the Cameca strategy towards PC based systems. The following facts and thoughts should clarify this point: - Cameca continues to develop its software in the Sun environment. Regarding only CPUs, PC and SUN are close: true. But, as our programs use more and more graphics, the overall performance is what really counts: our experience is that, for our applications, SUN performs up to two times better than Pentium. Moreover, up to now, we consider SUN operating system as superior to Windows NT, not even mentioning DOS or Windows 95. - However, for those users who are convenient and with PC/Windows applications, we have developed a new client/server option. The server is the SUN computer which runs the Cameca software. The terminals from which the SX can be controlled are PCs linked to the SUN through Ethernet. Thus, any Windows NT compatible application can run together with the Cameca software. Any portion of a Cameca display can be selected and pasted into Word 6 or transferred to Excel (for instances), and all files including those acquired within the Cameca system are managed through Windows explorer. It is really a Windows environment and it runs really fast for only a small additional cost. It is available by now and fully Cameca compatible. I hope that these review will have answered usefully to some of your questions. I keep the line on for answering to your interrogations or comments. P.F. Staub. From ???@???

I suspect your problem is in the FEX (file exchange) process and who is the owner of it vs who is the current logged in user. The version of the sx software I have does NOT kill the FEX automatically when the user who owns the process logs out. The first user from a reboot is the apparent owner of the FEX process. This is the process that allows you to 'talk' back and forth between the sx-local window/microprocess and your DEC/ SUN cpu - read in tasks, etc. If the current user is different than the owner of the FEX process, then tough tomatoes, you can't read tasks in to the local window, etc. (We locally here tried to patch that by adding a line to the logout script to search for the fex process id and kill it -- it works 75% of the time, not sure why not always). At least in unix, if you do a 'ps -aux |more' and look for the fex, 9 times out of 10, the owner is not you and that is why you can's do the file transfers. Try that using the appropriate VMS command. This problem has been reported to Cameca. I would hope something as simple and as aggrevating as this would have some priority amidst all the fancy new bells and whistles. john John Fournelle Electron Microprobe Lab Internet:johnf@geology.wisc.edu Dept of Geology & Geophysics Office: (608) 262-7964 University of Wisconsin Lab: (608) 265-4798 1215 West Dayton Street Fax: (608) 262-0693 Madison, WI 53706 Amateur radio: WA3BTA/9 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Ron, The ".img" file format used by the Cameca acquisition programs is not the same ".IMG" used in the MSDOS/Atari world (as DRI GEM image format). The Cameca version is actually the .img supported by NOESIS in their Visiview Image Analysis program. The Visiview manual discusses their .img format in some detail. It can quite easily be read by any graphics program that can read raw image formats AND strip off file headers. (I use "import" in NIH Image on the Mac). Note: an alpha version of NIH Image for Windows 95 (by Scion) is currently posted at the NIH ftp site (zippy.nimh.nih.gov/pub/nih-image/nih-image_spinoffs/IMAGEPC5.ZIP) I'm not sure if this alpha version can import images at this time. The 2 Cameca image-acquisition programs CIAP and FCIAP store the files in different bit depths. CIAP stores all electron signal and Xray images in 16 bit format. FCIAP stores Xray images in 16 bit format, but uses an 8 bit format for all electron signal images. The header length for all Cameca .img files is 1056 bytes, regardless of x & y dimensions; this contains information such as comments, acquisition conditions, etc. This is generally unreadable by all programs other than Visiview and is not needed to be able to display the image in a Mac or PC based program.

I have used their switches to replace the flow switches on the probe and other instruments. The design is less sensitive to clogging than the ones supplied with the MBX probe. There is a rotating "propellor" which spins a magnetic rotor, which then generates a voltage in a coil. The voltage is compared to an adjustable set point voltage and a 3A contact relay is driven according to the results. The last phone # I had for Proteus is 415-964-4163.

We use a MAC anf the NIH Image program to creat a tif or pic image which is usable by other IBM, etc image programs. Having a Mac on ether net using FETCH and the NIH program has worked very well here. I thank Ray Guillmette at Texas for much of my knowledge. From ???@???

The dates for future releases of cameca software are most helpful. Could you please also advise us about what will be part of this new software upgrade besides the new operating system SUN/Solaris 1? My institution is using Solaris 2.5 and we will not be compatible with them using Solaris 1. Since you are adapting the old SX100 software to the SX50 instrument, I assume you should be able to detail for us SX50 users exactly what the new software will consist of. How firm is your release date of September 96 for this package? Next, how will the "last" software version for SX50 instruments under Solaris 2.X be different than the other version (except the operating system)? How firm is your December 96 delivery date for this later version? I will contact our Cameca representative in the States about the PC/Windows new option that you mentioned. It is odd that they did not tell us about it. I look forward to hearing from you. Sincerely, Mike Garcia Geology and Geophysics Dept.

Don't know what incident beam potential would result in charge equilibrium for this material(s). Probably much lower than 5kV. Below 3-5kV, many diode BSE detectors do not work well. A scintillator (Robinson) type would be needed to view chemistry differences. On a fracture surface, topographical effects can easily mask small atomic number variations. Try evaporating carbon for a conductive film. This will let you use 5-10kV without disruptive charging. If the analysis requirements permit, a carbon coated polished sample would enable you to see (BSE) the smallest atomic number changes.

Autofocus alignment/tuning and optical microscope lamp brightness adjustment. 6. There should be a compilation of the commands necessary for resetting the SX after a power outage or electrical problems. This should include all the commands for resetting serial communications, vacuum, spectrometers, etc... Bruce Robinson writes : I am interested in the suggestions for dissemination of maintenance information. I did not know about cleaning the BSE detectors. [As we often run at 450nA, and 30 to 40 kV, I presume our BSE detectors are getting grubby]. However, we are normally faced with too much sensitivity. The BSE system seems to have been designed to work at SEM currents, and not at probe currents. It overloads (and the signal can invert, making white black and vice-versa). We have a suspicion that unplugging the spectro motor power cables is not as safe as it has been thought. I blew a LAS 3224 24 volt power supply module in the WDS power supply while I was changing a spectrometer motor. There are some precautions, but I am not sure if it is recommended to turn off the WDS power supply before changing motors. The LAS3224 is a very pricey module, and hard to get off-the-shelf in Australia. I think it would be nice if there were a set of on-line hints and tips (perhaps on the WWW, or on a database such as Access, available via FTP) where hard-won expertise could be shared. This could take some considerable time and effort to accumulate, but would be extremely valuable to SX owners. It would be practical for labs to subscribe some money (say $100 each) to pay for the expenses and time of whoever has to accumulate and sort all the hints. Ideally one could approach Cameca in Courbevoie to contribute funds (perhaps) but more importantly expertise. It could be appropriate for there to be some reward for the people who contribute most to the maintenance etc information base. Perhaps an occasional trip to Paris, or some more modest token. It is my impression that there is no systematic repository of written information on hardware within Cameca. Perhaps that is a strength, as the French engineers are generally very good and very knowledgeable. However, it does means that it is harder for Cameca to train new engineers, and it means that users do not have access to the knowledge base. With some sort of edited on-line system, we could accumulate lots of useful hints. One would go down a menu structure, searching on keywords or whatever, to seek hints for specific problems, or just browse through. There are some minor things that we have implemented here that could go into the list. Like how to get audio output from the spectrometers, so one can search for a specific element, how to get the transmitted and reflected light to work at once (and with BSE and reflected light), third party sources for common components (for economy, and as a backup), commonly used spares lists, complete O-ring kit lists. I am sure that lots of other people have many useful hints. I hope we can find a way of summarising the data. The on-line WWW and internet offers a lot of possibilities. Thanks very much for your efforts in assisting the communication between users. John Donovan writes : 1. Spectrometer/crystal install and alignment (especially for LDE multi-layers) 2.

Well, I made the switch and in the process I learned a few things about flanges, but I don't think it will help you. The turbopump connected to a ISO 160, K-type flange (that is, without holes) by means of double claw clamps. Since the diff pump was going to be a K-type ISO100, I had to get an adapter. Given your question, I take that SXs bought with a diffusion pump come with an F-type flange. In my case (a turbo from the start) the flange on the instrument side seems to allow for more than one configuration. One thing I still do not understand is why the turbo had an ISO160 flange, when its tube diameter was only four inches. Time and money did not allow me to follow your suggestion of installing a freon cooled baffle as well, but who knows ........ From ???@???

We will address in details the content of the new SX50 software, which is scheduled for September 96 (confirmation), as explained in my previous e-mail (dated june 7). I also confirm the delivery of the first Solaris 2.X version for December 96. Generally speaking, the new fully graphical SX50 software version, which is retrofitted from the SX100 instrument, will not only improve some previous applications, but will also bring a whole set of new analytical capabilities, some of which are listed below: - Graphical interface to Merlet thin films quantitative program. - Enhanced choice for the real time output parameters during quantitative analysis runs. - Enhancement of quantitative data processing capabilities: * New correction routine (X-Phi from Prof. Merlet) * Use of various standard intensities for unlimited process of one single acquisition file: free choice of the standard specimen among all those available, immediate creation of relevant calibrations from other ones made at different accelerating voltages. * Possibility to add data concerning precedently non analysed elements in order to complement an analysis and process it as a new file. - Improved integration of EDS signals into acquisition interfaces. - Improvement of the document handling for image displays. - Quantitative analysis at beam currents as low as 0.5 nA. - Graphical interface dedicated to binary and ternary phase analysis. - Interface for K-ratio map acquisition. - New standard file, including background measurements. - Queuing of tasks, including quantitative analysis. ... Some limitations of the SX50 reported by our users have also been fixed, including some concerning Quanti XYZ or FCIAP images. P.F.Staub. From ???@???

The graphite is more conductive, so you must use a higher current to get it to evaporate, but it is stronger and less likely to break off. I personally prefer the pressed carbon. In answer to your second question, I've found that if you can carefully tighten the rod in the holder without applying sideways stress to it, it is less likely to break. In my system that means tightening up the screws while holding the sharpened rod off the flat piece, then carefully letting it come to rest on the middle of the flat piece.

John, I think that you will find that a number of suppliers of carbon evaporation equipment now recommend carbon 'string', in preference to carbon rods. This 'string' is a multi filament braid and avoids precisely the type of problem you mention. Additionally, I think you will find that using 'string' the whole evaporation process is rather more controllable - does anyone know of any disadvantage of carbon string (apart from requiring a different evaporator head)?

When that happens I try to take care in how fast I bring the rod up to heat. Also allowing the rod to glow, cool, and then evaporate will sometimes work.

Is there any difference between using graphite vs carbon rods? I wasn't even aware that there is a difference. I use pre-sharpened rods, at the suggestion of two other labs on campus. The current batch is from E.F.Fullam, and they work just fine. I used to sharpen commercial rods in a oencil sharpener before, and we sometimes had problems with unsatisfactory carbon coats. I cannot say, though, whether it was because of the quality of rods (purchased in long pieces by someone in experimental petrology), or because tapered points are inherently worse than the cylindrical tips. >2.

My collets advance the rod quite a bit when they are tightened, and if you don't leave enough of a gap between them before tightening... If I do it right, it is very rare to have the tip break during evaporation, at least on the Fullam rods. Good luck, Alfred From ???@???

John, I think that you will find that a number of suppliers of carbon evaporation equipment now recommend carbon 'string', in preference to carbon rods. This 'string' is a multi filament braid and avoids precisely the type of problem you mention. Additionally, I think you will find that using 'string' the whole evaporation process is rather more controllable - does anyone know of any disadvantage of carbon string (apart from requiring a different evaporator head)?

The recipe: 1) obtain the two apertures. One can be gotton from Ted Pella , #60300, 2mm aperture, PT,300 micron. The other I get from Fullam, 150micron, Mo, 0.158 inch dia., 0.002 inch thick. Alternatively, both can be gotton from Cameca for about 2 to 3x $ more. 2) Carefully draw picture as the old assebly is taken apart. The 300 micron aperture must be pressed out. The new is inserted and held in with dings adjacent in the main piece. 3) Alignment is a trick and takes patience. Use only a monocular microscope. I actually use a student polarizing microscope. Using the adjusting screws, the small aperature can be centered over the 300 micron. This is checked by focusing up and down and observing transmitted light. Sounds simple and it really is. Best though to see someone do it. I actually have sketches of the assembly and step by step guide, but where I'm not sure.

Vesely and S. Woodisse (1982). Carbon coating with carbon fiber filaments, Proc. RMS 17 (3):137-139. "Precise and reproducible deposition of thin and ultrathin carbon films by flash evaporation of carbon yarn in high vacuum, J.

Carbon supporting films for high resolution electron microscopy- improvement of quality and preparation technique. Mikroskopie 31,1. In summary: Granularity depends in high-vacuum deposition on the predegasing conditions. If you predegase rods and yarn only shortly to dark red (to remove organics), you do not loose internally adsorbed gas molecules. These gas molecules are radicalized when evaporated with the carbon and will adsorb in flight to the carbon atoms preventing their crystallization. Therefore, yarn can produce as fine structured films as rods that are used only once. However, if predegased carefully, yarn will more consistently produce very fine structured films since the amount of deposited carbon can very accurately be controlled by the lenght the amount of yarn and the distance to the object.

SPI produces both products, and the "basic fiber" is the same for both products. I will refer to both as carbon "fiber" but I am speaking of both forms of the product. Individual carbon coaters are designed to take either one or the other or both. The SPI Supplies carbon coaters can use either. It has been our own experience that under the best of circumstances, the granularity of a carbon coating deposited with carbon rods (but in a soft and not a diffusion pumped) vacuum is a bit smaller (e.g. slightly smaller grain size) than what is possible using either of the two mentioned carbon fibers. The only people who we have encountered over the years who seem to possibly find this smaller grain size to be beneficial are those looking at submicron particle size particles on membrane filters. There is a point where the grain size of the evaporated carbon starts to get confused with particles of interest collected on the filter membrane. Another advantage is that the process, at least in the SPI carbon coaters is much faster, almost as a "flash" evaporation, that is, it all happens within a time frame of a second (or less), and therefore neither the sample or the "head" itself tends to have any "heating" problems. Using the carbon rods, however, it is a slower kind of process, exposing the sample to much more radiant heat as evidenced by the much higher temperatures taken on by the head. And because one has to wait for the carbon rod head and posts to "cool down" where as the carbon fiber head never really does get that hot, the "throughput" of samples when carbon fiber coating is employed, tends to be much faster. The degree of control of what we call the "flash evaporation", and the ability to reproduce coating thicknesses, sample to sample, is related to the homogeneity along the carbon fiber, probably the most difficult parameter to control in the manufacture of these two particular products. However, the control is more than adequate, at least with our particular products, that coating reproducibility does not seem to be an issue. There is another (apparent only) disadvantage and that is the difficulty imparting ultra high purity to the carbon fiber. With the carbon rods, the standard purity (from SPI at least) is 5 ppm ash. However, we have never been able to produce carbon fiber or braid down to that level and have it still retain its desirable mechanical properties. So the purity of the fiber tends to be on the order of 10 ppm ash, perhaps even as high as 12-13 ppm ash. However this is still well below the level that the typical EDS user will detect any of the impurities. So in the end, although the best purity of the carbon fiber tends to not be quite as good as the best purity carbon rods, a "reality check" would suggest that in the end it still would not matter to most persons. And forgive me if this now sounds like a commerical statement, but all carbon fiber does not come from the same place! Further information about the two different SPI carbon fiber products can be found in the SPI "electronic catalog" at our web site given below. Look up in the catalog table of contents and then under "sample preparation" and then under "evaporation supplies". Chuck ====================================================== Charles A. Garber, Ph.

Here is Tony's response: >From: "Tony King" >To: ebs@ebsciences.com >Date: Tue, 2 Jul 1996 15:16:15 +0000 >Subject: Re: Carbon "string" vs. "rods"` VG Microtech, as a manufacturer of carbon evaporation equipment does "recommend carbon 'string', in preference to carbon rods," but only for reasons of ease of use. Actually, carbon rod evaporation should be more controllable. You try to gauge the thickness of carbon laid down by string, but with the carbon rod method it is possible to control the length of burn and, therefore, the deposition. The main reason we have come across for the rods breaking is when the rod has been formed by sharpening, which introduces micro cracks. The carbon rods should be ground to shape. As Chuck Garber mentioned, "under the best of circumstances, the granularity of a carbon coating deposited with carbon rods (but in a soft and not a diffusion pumped) vacuum is a bit smaller (e.g. slightly smaller grain size) than what is possible using either of the two mentioned carbon fibers." We believe this is due to the massive deterioration in vacuum when the fibre is flashed. The process time with rods should only be 1-2 seconds longer (at least in the Polaron carbon coaters). If you push enough power through the carbon rod, it will also flash instantly as the fibre appears to do. Chuck continues, "Using the carbon rods, however, it is a slower kind of process, exposing the sample to much more radiant heat as evidenced by the much higher temperatures taken on by the head." This is a debatable point, as the heating is by transmission through the metal. To evaporate, the carbon must reach, I think, about 2700 degrees C. Mass for mass, the same amount of energy in watts will be used. The Polaron systems have a shutter to protect the sample during outgassing. They also have switchable power supplies for the use of any fibre or rod. As for the issue of relative purity, there are often higher peaks of sulpher in the fibre (no statement toward any individual commercial product is being made here). Also, note that the fibre can fall as spindle-like shards onto the sample surface if handling is rough. >Regards, > >Tony King >Product specialist >VG Microtech/ Polaron range > >Tel: +44 (0)1825 746251 >Fax: +44 (0)1825 768343 > >Disclaimer: >The views and opinions expressed are not necessarily >those of VG Microtech. > Further information about the Polaron carbon coaters can be found at the Energy Beam Sciences web site (http://www.ebsciences.com/).

Donovan) To: Multiple recipients of list Subject: boy is this probe hot! X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Status: RO Well I should say that this probe stage is hot! We ran some small samples, that need to be removed and dated eventually, mounted in "crystal bond", and although this worked fine on the old probe, on the SX-51 they just melted away. It took several days of running (over the weekend) to do it, but they just either melted and sank down into the brass sleeves or bubbled up (from internal air pockets I presume) (we had first run most of a day without seeing any changes I should mention). On a possibly related issue I notice that after the beam has been on the samples for an hour or two the optical focus is quite different. Usually around 5-15 microns from when the samples first went in. I thought at first that it might be the stepper motors or electronics heat percolating to the sample block and causing expansion, but now I feel that it may be the beam that is doing the heating, since if I leave the faraday cup in for several hours after changing samples, the focus doesn't change. Several questions : First, I assume that a warm to the touch stage is normal for this machine? I notice that the heat just pours out of the slots under the airlock. Next, do other users notice that the optical focus changes after several hours of running with the beam on? Finally, is there an alternative to crystal bond? We need something that is easily dissolvable for removal of the specimens later. Is there a higher temperature version of crystal bond? john ==================================================================== =========== John J.

We have just had our second water flow detector front crack, I have found that as a temporary measure you can repair the crack by placing a drop of chloroform on the crack which welds it closed.

I have a spare assembly, the theory being that the spare one will be ready to go when the one being used fails, but notice that I said 'theory'. The top aperture (300 microns) can be cleaned and reused, at least once, using care, an abrasive paste (I use Wenol or Pol), a toothpick, no-lint wipes, acetone and an ultrasonic cleaner. The bottom aperture (150 microns) I replace. I have always used Mo apertures, but I am told that Sam P. has also suggested Ir-Pt. The latter are bound to be more expensive, but can be cleaned in air by flaming; the former you can also clean in a vacuum evaporator, by indirect heating on a Mo strip, for example, and making sure you have good vacuum. VENT CHAMBER, remove the multiple aperture assembly, and remove the current regulation assembly, by removing the two bottom screws and paying attention not to damage the electrical connection. The top aperture is fitted in a cup shaped support, which is held and positioned by centring screws. The aperture can be pushed out from the bottom, although in the first assembly I received the edge of the aperture had been deformed to keep it in place (push harder, in this case). The lower aperture is asymmetrical, and the dish shaped side should be the one facing down. It is held in place by a threaded collar pushing on a 'washer', which John F. says is made of graphite, but I do not remember. More interestingly, John Fournelle reports that there is a suggestion that the graphite contributes to the aperture's contamination build-up. The two new apertures must be centred on the same vertical axis. For this a transmitted (and reflected) light microscope is needed. First, focus on the outline of the lower aperture, centre it at the microscope crosshair, then refocus at the upper aperture level and check that it is also similarly centred.To get to this point you will need to reposition the top aperture using the centring screws, and go through this refocusing business a few times. To do the above you also need a jig, to hold down the assembly. I have an aluminium plate, the size of a standard glass slide, with a 1 cm diameter hole in the centre (also remember that top and bottom surface must be parallel!). The assembly can be held firmly against the plate by any means you can devise, provided it gives you easy access to the centring screws. I use two square brackets, one permanently screwed onto the plate, while the other is tightened against the plate and the assembly, by means of a screw through a largish hole in the brackett. When reinstalling the assembly, verify that the assembly and the bottom spring-loaded 'washer' are in good electrical contact. I hope this helps. Maybe a bit long, but I didn't want to be too concise. From ???@???

Hot means "good" in CA. X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Dear John, Ouch! Actually, the microstepping motors are normally hotter than the older servo motors. What I don't know is if the stage should be affected at all, and therefore apparent Z position. For a simple test, could you please focus on the shuttle/holder itself, not the sample, and leave the beam off overnight? I suppose the beam does heat up certain samples and possibly the surrounding mounting medium. If this turns out to be the case, would a thicker C-coating, or metallic coating (Al? with obvious shortcomings) be useful, if another more stable medium is not out there? Also, maybe the combination of warmer (cozier) environment plus better sample chamber vacuum makes the crystal bond out-gas and shrink more. You can reach Sam at Cameca/Paris through Pierre Staub.

I have used Pt apertures (available from Energy Beam Sciences) for both beam regulation apertures with great success for the past 10 years on our MBX. I suspect they will also work well in the SX. They are *much* easier to clean than the original Mo apertures, requiring a quick flaming in a Pt boat. After several (10?) flamings, the hole shape may distort. Then it's time for a new aperture.

We still have a need to carbon coat topographic samples for EDS. In which case resolution does not enter the image when one is using barge pole probe diameters to get enough signal. It is difficult enough having to view samples with the relatively poor carbon coating and this is made worse if there is high topography. Directional coating results in a preferential coating of the surfaces facing the carbon source. The solution is to have a rotating sample holder that effectively presents all aspects of the sample to the source at some point in time. This thus requires the carbon source to evaporate over a reasonably long period of time and can not be achieved by "flash" evaporation. So rods remain the best. I agree with Tony King that rods are more controllable, and, can suit more applications - from making very thin carbon films to topographic coating. If one is only coating flat polished samples for microanalysis and wish to reduce operator and other variables then carbon string may the better method for standardization.

We use carbon cord (braided string, fairly thick), and this glows for long enough to evenly cover a rotating sample of complex topography. The only trick is to have to sample rotating before you start applying current to the cord, and to apply the current moderately slowly ("slow, but a little faster than not-too-slow", the usual sort of quantitative method). This lets the cord glow white-hot for some seconds before burning through, long enough that the current can be turned down before burn-throug. The coating thickness can be controlled this way. We haven't used carbon rods for some while now, and our users seem pleased with their results Phil &&&&&&&&&&& Illigitmi non carborundum &&&&&&&&&&& Philip Oshel University of Illinois Rm 74 Bevier Hall 905 S.

Is this the same as yours? I am careful cleaning this. I have never ultrasonicated this. I might use something like alpha-alumina on a swab or Revere Copper cleaner, but not Wenol or Pol.

We have currently on the market a range of digital flow meters with variable interlock setting. Our meters utilise the use of opto electronic flow sensors for fail safe operation. The flow rate and interlock relay set points can be displayed on an lcd display and audible warning of low flow and flow failure is available. I am sorry for the late submision of this but maybe I should read my post more closely. I can fax you a product brief and prices if you require. best regards tony Tony Coyne T.C.

I use pure ThO2 and UO2 standards. The ThO2 is part of a set of standards that existed with our "old" probe. I tracked down the UO2 in the Chemistry dept. here at Rice Univ. It was labeled 99.9% pure and our geiger counter does not respond to it. We have found zircon with as much as 0.8 wt% UO2. The oxide gives much better results (precision) than the borate glass with 5% UO2 on hand before. While I do not have any extra of either of these oxides, I wanted to let you know that these work well for us. -------------------------------------------------------------- Milton L.

Myra Funkhouser and I had some success in identifying monazite in thin sections of granite using autoradiography. We used a cellulose nitrate film available commercially as CR-39. A piece of this flexible plastic film/sheet is placed over a thin section and with sufficient exposure (a month or so) becomes damaged by radiation emanating from radioactive minerals. After exposure, the film is etched in an alkali solution revealing areas of structural damage caused by the passage of alpha particles through the detector. The spots are readily observed with an optical microscope along with the thin sections to identify minerals with high concentrations of radioactive elements. Of course, this method only identifies U- and Th-rich accessories, but in our experience monazite, uraninite, and thorite were the only minerals able to damage the CR-39 film during exposure times of a few weeks. See Basham I.R. and Easterbrook G. D. (1977) Alpha particle autoradiography of geological specimens by use of cellulose nitrate detectors. Trans. Inst. Min. Met. London, v. 86, section B, p. 96-98. Fission track mapping is another approach that has been used to identify radioactive minerals. In addition, there are probably more sophisticated autoradiographic approaches that could be used today. ________________________________________________________ Eric H Christiansen Department of Geology Brigham Young University Provo, Utah 84602 E-mail: eric_christiansen@byu.edu Tel: (801) 378-2113 Fax: (801) 378-8143 ________________________________________________________ --------------33B72A4E4E38-- From ???@???

I would like to bring attention to a couple papers discussing the use of electron microprobe analyses of Pb and U for dating. This works well for monazite, zircon rarely has enough U. I learned of the method from the work of Jean-Marc Montel in Clermont-Ferrand, and we have used it here in looking at granites in the Erzgebirge and Fichtelgebirge of Germany. Obviously this is a quick and dirty approach, and no substitute for isotope analysis. But it is, I think, a useful addition to the CL and BSE methods as a reconnaisance tool and a way to screen samples likely or unlikely to give useful results by bulk isotope analysis.

England by microprobe (The dates of these granites are well known, we want to test the method first). My approach has been to survey polished mounts on our S.E.M. using the B.S.E detector, this gives a good idea of the zoning and alteration, and also shows other uranium and thorium containing phases present (thorites and uraninites). I have been using UO2 and pure Thorium as standards (we did purchase a thorium oxide standard but the grain size of the material sent was too small). I also have a piece of monazite (1cm x 1cm) that has had an analysis made by solution ICP-MS after an HCl-HNO3 dissolution and had the homogeneity checked by LA-ICP-MS. I am currently using this to improve on the detection limit and precision in analysing lead, I have recently started to analyse lead using the La line at 30+ kV the monazite is stable at this kV and after repeated counting at the same point the Lead measurements can be reproduced, I have also been using the CSIRO Trace program for the analysis. I would be grateful for any comments from anyone who has tried this.

Our Coolwell has been down for a while and I have been spliced up to a Haskris which now runs two machines. I suspect that the thermostat is the problem (again!!) and have purchased the T6031A. My question concerns the hook-up. There are three electrical connections marked R, B, and W. We are not sure which wires go where, and the people form Honeywell have suggested that hook-up location may vary depending on temp range????? Sounds a little scary to me. Anyway, any input from your end would be greatly appreciated. Cheers Dave From ???@???

SAMx has provided me with a number of individuals' e-mail addresses who might be interested in subscribing to a SAMx list. I have created such a list and as long as it doesn't involve some inordinate amount of my time (it doesn't appear so ...), I can moderate the server and possibly centralize a U.S. site for exchange of relavent files (via anon ftp), as well as exchange of information ... NOTE 1: I'm taking care of this initial invitation via my home so my return address is ^not^ appropriate ... if you choose to e-mail me regarding this list please direct your e-mail to my mshaf@oregon.uoregon.edu address. NOTE 2: To subscribe to the list (SEE below), but before you do I want to make you aware of the list server sometimes "gagging" on special characters. For example, I have experienced problems with subscribers including "international" characters in their nickname, e.g., nickname I'll know immediately if there is a problem, but if any of you don't receive notification of the successful subscription then you may want to contact me. If any of you can configure your e-mail software to send ^only^ your "raw" or basic e-mail address as your "return" or "reply" address, then please do so and reduce my work. NOTE 3: I have also seen a problem where a person's e-mail address is one thing, but the address as interpreted by majordomo is another ... again, a successful subscription will be followed by notification ... please indicate by e-mailing me of suspicious behavior. The "mode" of this list server is that ^only^ subscribers are able, and any messages to the list are e-mailed to: samx_sig@lists.uoregon.edu and that "replies to list messages" are sent to the originator of the message, as opposed to sent back to the list. I have configured the samx_sig list this way because of my experiences with lists. I don't, by any means, want to keep replies off the list as is many times appropriate ... its just that ^generally^ "appropriate" means "back to the originator", and also keeps traffic to a minimum. The "anonymous FTP" site I mentioned previously will be independent of this list, but I ^do^ have the means available to make such a site a possibility. Lastly, NOTE 4: to those of you who are not familiar with "lists" ... two e-mail adresses are involved (1) "to the list" and (2) "to the list server". All subscribers MUST keep both addresses, ... the latter is important if you ever want to "unsubscribe" or change your address , or troubleshoot your list status. Upon subscribing (successfully) you will be notified and will be given all you need to know regarding "both" list addresses ... ^PLEASE^ save the information ... Also, regarding "list etiquette", "attached files" are to be avoided ... such files are generally not of interest to ^most^ subscribers. On the other hand, notification that such files are available is incouraged and, indeed, is the purpose of this list. ... okay, ... okay, enuf already ... the procedure for subscribing is to send an e-mail message to: majordomo@lists.uoregon.edu with nothing in the subject and ^ONLY^ (no signatures): subscribe samx_sig end in the message body ...

I set up an analytical procedure for Si, O, Ge, and B with SiO2 as a standard for Si and O, pure Ge as the Ge standard and pure B as the B standard. If I then run the PAP corrections backwards, I get the following intensity ratios (relative to pure Boron) for the following two compositions: wt. % B I.X/I.Std. ------- ----------- 1% 0.0009 11% 0.0126 for the 11 wt% B, I assumed that Si was 33 wt%, just for quick calculation. As you can see, the B intensity expected from your sample is very low relative to pure B. Unless your intensities from pure B are high, you will have a difficult time measuring low levels of B, regardless of any spectral interferences. To evaluate spectral interferences, run some spectrometer scans over the B peak on pure Si, pure Ge and an oxygen standard (SiO2?). Look at possible n-order interfering peaks. You may be able to adjust the PHA baseline and window width to eliminate some interferences. If you have a lead stearate "crystal" you might try running the same spectrometer scans for comparison. The stearate crystals tend to have better spectral resolution, though lower count rates and more susceptibility to n-order reflections. Hope this helps. Tough problem.

Unfortunately his notes are vague and I cannot offer any real help. I may point out, however, that in most cases I could 'restart' the counters either by switching to a different xtal and then back or, as I learned later, more simply by a CONF INIT, both of which point to xtal definition/initialization problems. I have always wondered why I was not instructed earlier to replace the component that Edgar did replace.

The fix is to SACQ DTIM SP1 2 ... or whatever spectro and value you use. Oddly, the spectro may display a deadtime of 2, but resetting the deadtime brings the spectro back to life. Cameca has been no use on that problem. On another note, still have had no luck on the lack of communication between the SX and the DEC in local mode. The lack of factory support is overwhelming.

Users could return in the morning and find either a neatly folded stack of output or, if the printer jammed, a crumpled sheet with one very black, overprinted streak of ribbon ink. With the advent of QuantiView we never have to worry about a jammed printer anymore because there is no longer any possibility for automatic printing after quanta. Although the QuantiView guide indicates that automatic printing is still possible by clicking the appropriate box after mousing the QuantiView OPTIONS button, alas, it is but the glint pyrites and has no effect on the quanti_options file. Hard copy in these modern times must be requested specifically with the PRINT ALL mouse click. But all our quanta users would like to the option of having it both ways. And believe it or not, they still want paper with numbers on it to carry away. Does anyone have a work- around for this feature of QuantiView? How to make quanta print automatically. It would be nice to have a command in the REST task that would initiate printing, but the only scheme we've come up with is so kloogey its embarassing. Here it is anyway: the REST task writes a file to the user's Sun directory. The Sun program CRON looks for that filename every so often. When CRON finds it, signalling that quanta is done, a script is executed from the Sun which deletes the file written by REST and sends the .quanti_run file to the printer. One problem with this is that the file that gets written by REST goes into the directory of the owner of FEX. And ownership of FEX is set by whomever is the first to login after a reboot. So for this scheme to work the current owner must make sure to own FEX. But there must be an easier, less convoluted, way to do this. Any suggestions for a better way are welcome.

The trick I found to overcome this difficulty is the following: Just before launching a series of automatic or manual points, open the options window, go to the spool device line, open the pop-up menu with the right button of the mouse and select "/dev/lp", EVEN IF IT WAS ALREADY SELECTED!!, then store and quit the options window... and that's that! Don't ask why, but it works fine. In some cases, after leaving the analysis program, and reentering it later, you get an error message saying that the computer cannot open /dev/lp; in this case, leave completely Quantiview, then reopen it, go to the options and do the same as above. We have no more problems with printing automatically since we found this funny trick... Good luck Francois P.S.: of course you need to activate the "printing results" in the options too!

The last three months have been quite dense in terms of probe problems. Most recently, a powerful brownout, maybe a very quick temporary power loss, has decided that I had suffered enough, so it only left behind a marginal problem, the following: 1) the DEFK command returns an "address error at 001209F PC= =/-0008B67A from DEFK"; 2) when opening the QUALI Acquisition window, the same message comes up, this time "from PRIN", as well as three "sx1:timeout on read", while the process 'scanacq_init' is active; then the window opens and it is usable. Resetting does not clear it. Any suggestions? Prior to that, an electrical storm had been less kind, leaving a trail of problems, which required replacing the coil of electrovalve EV1 and its fuse F4 with one having a slightly higher rating, so that it would not keep blowing. Talk about close tolerances! The interpretation of associated symptoms also led me to check for leaky detector windows, and that part I shall condense as follows. Detector windows are sturdier than one would imagine, but, if trying to fix one with some nail polish, do not use a toothpick; a tiny brush would probably be better. On my second attempt I used a very thin strip of Al foil, light and flexible. Like others before me I can report that nail varnish works well and that, in small amounts, has no visible effects on x-rays transmission. I also found out that you can remove a window from the counter and then reinstall it if you paint a thin layer of Ag paint to replace the ring of metallization that adheres to the O-ring when the window is removed. In this experience I benefited from other SX users' advice, which has also encouraged me to look for more information about detector windows. I shall report on it when the quest is over. Regards to all. From ???@???

When the pressure in the column is low enough, you can also erase the default wait time for turning on the ion pump via the "PUMP GUN" command.

Twice in the past three months we have experienced rather major probe melt downs, apparently due to a high voltage surge from somewhere (whether externally or internally derived is yet to be determined). Symptoms include loss of parallel communications on both WDS and SEM 68000 boards (fried PIA's), loss of vacuum system (damage to both Vac Logic and Analogic boards, Cie Puissance Vide), burn out of the Farnell 5V supply in the WDS power supply, damage to Numeric 1, damage to Control Column, etc. The engineers at Cameca suspect either an externally-derived spike or ground loop problem. We have difficulty believing an externally-derived spike on the hot lines, as our main power comes from an isolation transformer, goes to a BEST UPS (ferroresonant transformer type), then to the ONEAC, and finally the probe is plugged into a surge-supressor receptical. That a surge was generated somewhere seems to be indicated by the fact that the surge suppression capability of our receptical is knocked out and there is a small amount of carbon soot on the inside of the receptical case. As for grounding, at the time of the incidents the SX50, both input (primaries) and output (secondaries) of the ONEAC were firmly affixed to a dedicated local earth ground, along with the ground strap from the UPS and the building ground - the latter two could have induced a ground loop. Has anyone out there, especially those of you using an uninterruptable power supply, seen similar types of surges either from within or external to their instruments? As of this week, things were re-wired such that only the SX50 is attached to the dedicated (isolated local) ground. Yesterday, I was informed by Bruce Barnes of Advanced Micropower that the secondaries (output) from the ONEAC should also be attached to the local dedicated ground. I am uncertain of this, as the ONEAC is internally grounded (both primaries and secondaries are in common with the case, thus it seems to me that grounding the secondaries to the dedicated ground would also ground the primaries in common, thus opening up a channel for any spike generated upstream to see the probe). Bruce Barnes also suggested that the computer which runs the probe (in this case a PC running SAMx) should be grounded in common with the probe, because as the 110V that runs the PC is grounded to the building (source) this generates a ground loop to the SX50 through the RS-232 serial communication lines. Does anyone have recommendations for grounding? Any input would be appreciated. Many thanks.

I can offer no help, only condolences. And I'm happy to hear that someone is worse off than I am. About grounding - a local power engineer also told us that to avoid ground loops, our computer, and any other toys connected to the probe, should be on the same ground as the probe. The power suveyor also told the university that the building ground should be cad-welded to the water main, rather than simply clamped on. This makes a better connection. However, the plumbers said 'not on our pipes'; they say it weakens the pipe.

I shall not rejoyce, but I'll be thinking of how best I can use your message to make people in this Department more aware of the fact that ALL probes can and do breakdown and in the process inconvenience the users (not to mention aggravate those who have to clean up things). I have shown your message to our local expert and I pass along his comments: he feels that the surge was generated internally, but he is not too clear about how exactly components relate to each other and to to the various grounds. It would be useful to determine the direction in which component failures took place, but more detail is needed to decipher that. In his experience, ground loops are quite important when dealing with low signals, but, somehow, he doubts they were a problem in this case, although he feels that you may have too many grounds, i.e. that increasing the number of grounds does not necessarily mean more protection, and in fact it may end up meaning less protection. The above is of little practical help, of course, but he is curious enough about the whole business that you should feel free to send more information in his direction. If the surge generated within the probe system, I am sure we all would like to know how.

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas I've had lots of experience with the gas pressure changing mainly due to more blockage at the gas restriction brass tube in the bubbler. Using pliers to partial try to open the solder/indium? brass tube is how I fine tuned the opening. I had a piece of tubing into diff pump oil. Also, just reducing the pressure regulator should do the trick. I would "TPHA #" and then either increase or decrease the gas regulator for that spectometer to the bias I wanted. To high a pressure gave me smaller ghost peak for say Fe Kalpha. Regards, Todd Solberg VaTech From ???@???

There is a known bug in that the "Update Declare" button in the Utility window does not work. I recalled and found Fred Scott's communication of almost 2 years ago, I think some of the bugs he lists may have been fixed in the most recent patchup we received last year, but list them all in case some of you may be encountering some he mentions. (I tell all my users to delete all old calibrations that are on same standard, same crystal and same operationg conditions; this option pops up just before you get the Store option in Calibration.) --johnf ================================================ Date: Wed, 7 Sep 94 15:20:36 +1000 From: (Fred Scott) To: johnf@ice Subject: Bug list etc. I have sent my bug list to Andy Davis and have listed it below for your information. 1. "Update Declare" in File Utility does not work. The only way to store updated calibration data is to select "Declare", delete the appropriate element from the declaration, then Insert or Append the new data. ("Declare", "Show" displays the latest data stored in stdint.dat, not the data actually used in an analysis. "Analyse", "Change Conditions", "Show" displays the data used in an analysis) This bug is known by Cameca but has not been corrected. 2. File names difficult to read after "Update Declare". Even though it doesn't work, the display of file names when attempting to Update Declare is confusing. 3. Wrong dates in calibration data. Click on "Analyse", select label, "Change Conditions", "Show". Incorrect dates are displayed in the calibration data. This bug is known by Cameca. 4. Analysis, Type: Difference only works for Oxygen. Selecting other elements doesn't work. I can select any element "By difference" and "Store", but the unanalysed element is actually stored as O. 5. Last analysis is not stored in .quanti_run or .quanti_point This has been rated as a low priority bug by Cameca. 6. Comments in X,Y,Z - Stage Scan When entering a stage scan, there is no problem if the comment is entered BEFORE the start and stop points are validated. If the comment is entered or changed AFTER the start point is validated, the co-ordinates of the start point are changed to an impossible value. A bug patch has been received for this problem. 7. Length of comments in X,Y,Z - Stage Scan Various problems arise if the comment contains 24 or more characters. A bug patch has been received for this problem. 8. Comments in X,Y,Z - Stage Point can cause problems. No problems occur if no comment is used, but the stage co-ordinates or the comments are stored incorrectly in xyzpos.dat unless the following procedure is used exactly: (a) Click on "X,Y,Z" (b) Point 1: select label enter comment for point 1 (optional) click on "Stage Point" select Autofocus (optional) (c) Point 2: move stage to position 2 click on "Add" change label (optional) change comment for point 2 (optional) (d) Point 3: repeat procedure for point 2 (e) Point 4: repeat procedure for point 2 etc 9. Comments in Reports . When comments are displayed in a Report they appear to be padded out to 60 characters with spaces and a "-" or "-1" at the end. 10. XYZ co-ordinates not possible in a Report. No predefined variable is supplied for stage position. 11. Problem printing results after each analysis. In "Analyse" mode the results of an analysis can be printed after each point if the spool device is set to /dev/lp or /dev/ttyy01 under "Options", however I have not found a way to make this permanent. Regardless of whether the Options are "Stored" or not, the spool device appears to be reset to /dev/null after logging off and on again, after quitting Quantiview and re-starting it, or after a Declare. 12. Extraneous error messages. "ttysw - TIOCSSIZE: Bad file number" error message often appears on CONSOLE screen after clicking on Analyse. 13. Blank screen after Qualitative WDS scan. After a Qualitative WDS scan, selecting an optical image results in a blank screen. Selecting one of the spectrometer displays and then selecting the optical image restores the image. This bug is known by Cameca. WISH LIST 1. Fix up these bugs. 2.

I notified Cameca of this bug in Quantiview 3.0 three years ago, but at that stage they were presumably working on the next version of the software and not too interested in fixing bugs in the (then) current software. Firstly, "Update Declare" simply doesn't work. Clicking on "Declare" and "Show" displays the latest(?) calibration data stored in stdint.dat which may or may not be the same as the data stored in one of your declaration files (I don't know which one - perhaps in binary form in xxxxx.exp?). My instructions to all users is to recall their old declaration file, delete all entries, then insert the most recent calibration data and Store it. You can always check which calibration data is actually being used by clicking on "Analyse", "Change Conditions" and "Show" - the dates are wrong but the data is correct.

But there is a way to sort by date, not perfect, but better than nothing-- in Quantiview, under Utility, select Intensity, and for Page 1, change Sort to by DATE -- then the calibration files in Declare will appear in dated order, albeit with the most recent at the bottom.

After that we had negotiated an additional two years of full coverage on the spectrometer and stage mechanisms. My thinking was that since these are the major mechanical parts, they would be the most subject to failure. However, I would like to start a service contract at the end of the first year warrenty period, but wanted Cameca to discount the standard service contract since the stage and spectrometers were already covered for another two years. Without revealing (yet) their discount offer I would like to hear from everyone exactly what % they would expect Cameca to discount the standard service contract based on the fact that the stage and spectrometers are already covered. After I hear everyone's ideas on the subject I will reveal Cameca's offer and we can see how reasonable it is. john ==================================================================== =========== John J.

Viewed at TV rate at >50,000x the interference seemed to have a fairly high frequency and underwent rapid variations in amplitude. Some days it was there and other days it wasn't. It was indeed caused by a mechanical vibration -- but in our case it was coming from the stage motors, in particular the Z-axis motor. The effects of this vibration only started to become visible above about 15-20,000x, and it could only just be felt on some days by very lightly touching the motor once you already "knew it had a vibration". Our Jeol engineer was the one who finally figured this out and then he measured a ~2 volt sawtooth ripple on top of the DC holding current to the stage motors. The problem was eliminated by changing some resistors in the (non-Jeol) motor driver hardware, on the recommendation of its vendors, to reduce the DC holding current and hence presumably the absolute magnitude of the ripple that came with it. We have not had any trouble since.

Garber, Ph. D. * EMC.Ver #3.0 ] -- Twice in the past twenty six years we had mysterious problems arise that had all the symptoms of stray AC fields which caused various problems with the images on what were then JEOL JSM U3 SEMs. In one instance in particular, quite a bit of major equipment was brought in (and dollars spent) to find the source of the field but to no avail. The proposed "fixes", and with no guarantees, included extensive "mu" metal shielding of the microscope room. However, by going around and turning off individual circuits in the building, and finding out which "circuit", when "off" caused the problem to go away, in one instance it was traced to a ground feedback loop from a vacuum pump with windings starting to fail. And in the other instance , which was a little more challenging, it was traced to a compressor motor that was part of the microscope itself, with (apparently) the same problem, windings starting to fail on the motor. In both instances, replacing the failing motor (or pump), the problem disappared. So while expensive and complex solutions are sometimes necessary, don't sell short what might be accomplished with the good old common horse sense approach.

One avenue that we are examining is mechanic vibration in the column due to the location of the EDS dewar. The dewar is essentially a large undamped liquid mass hung out to the side of the object that must remain vibration-free. Well the location of the dewar is approximately equidistant to the two adjoining sides of the room. By placing a small mirror over the top of the dewar, we can watch the LN2 shimmer. By moving sound-absorbing foam sheets around the area between the dewar and the walls, we can see a difference in the vibration. We have more work to do on this, but it seems like the dewar is in the "sweet spot" in the room if you were going to set up a stereo system. We are also going to move the 3-phase transformer that sits on the other side of the wall (less than 3 feet from column and console) in the surface analysis lab to get rid of the known electrical vibration. ------------------------------------------------- Harold J.

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Dear users. I would like to comment on the very interesting question brought to you by J. Donovan regarding CAMECAs service contracts. First of all, if I may, I would like to correct Johns statement on the two years extended warranty for the Cameca spectrometers. Nobody needs to negotiate it, as it is a standard offer which comes with every SX50 and SX100 sales and reflects CAMECAs confidence in its product. Pricing a service contract is an other issue and a very difficult one. Should and could we charge more for a 5 WDS instrument than for a 3 WDS? Should and could we charge less for an SX without Anticontamination attachment than with one? Should we charge more a novice user than an experience one? Should and could we charge less for a single user site than for a self service type of operation? For somebody who uses the instrument as is or modifies it ? For a Laboratory with a high or low turnover of users, for high usage or for low usage? etc., etc... Cameca does not have the resources to manage 50 or more different service contracts. Two or three at the most. Every user experiences a mixture of the cases above and on an average it is fair that every one should pay the same price for the same service contract option. The bulk of the cost of a service department is in maintaining a well trained service group. This is what you are paying for, no matter what instrument configuration you may have. Consequently, if our present service contracts are not appropriate we are ready to listen to you, preferably as a group.

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas One of our user, Dr. Ben Hanson, did an interesting test on one spect.of our 1.5-yr-old sx100 probe: He moved one spect. to a selected position on the deep slope of Al KA and count 10 sec on an Al-rich std. He repeated it several times by approaching the same position from low end and high end. The counting rates have excellent precession but fall into two groups: one is distinctly higher than the other; and the differece is equivelent to about 15 sp. steps. Theoretically, we did not expect to see such a different because the spectr. moves to the same spot according to the engraved slide - unless there is other mechanic backlashes somewhere we don't see. This test seems solve a mystery we usually encountered: Sometimes the quantitative analysis of std against itself comes out flawless and sometimes it is off by 1 - 1.5 % even we just re-calibrate the std table. For instance, if you analyze Si and Al on the same spectromenter, you "might" see differece depending on whether Si or Al is analyzed first. We are going to test further to confirm Dr. Hanson's finding. Meanwhile We'd like to hear from other sx users about similar situations. S.

Va Tech Todd is correct. For Cameca users with the RT11-based EDS, it is necessary to halt the PGT hardware last, and turn it on first, before the Sun. The reason for this is that the PGT hardware contains a disk and a disk controller which are connected to the SCSI bus, and it is necessary for everything on the bus to be turned on before the Sun starts to boot. Conversely, of course, turning off items on the bus when the Sun is running causes the Sun to be unable to read from or write to its disks, with unhappy consequences. For those users with CD-ROM drives or other accessories on the SCSI bus, I would recommend the same approach - don't turn it off while the Sun is running. This is not necessary for systems with PTS EDS acquisition, which has no SCSI bus connection. Regards, Margie Mott PGT phone: (609) 924-7310 fax: (609) 924-1729 email: margie@pgt.com From ???@???

Sad it is in binary now, but there must be a code to read it.? However, it would also be nice if there were an equivalent list of hardware/electronic bugs, work-arounds, fixes, cautions, upgrades etc. Cameca have a wealth of information, but most of the information in the past was passed from engineer to engineer informally, rather than being distributed in written or electronic form. I am not sure if there is now a more formal system. Other organisations, for instance computer companies like DEC, once had paper-based systems to keep the field service engineers informed of upgrades, problems and so on. This was when lab computers had service contracts, and service engineers. Perhaps we should ask Cameca to consider providing their hardware bug-fix information, perhaps for a modest charge, to users and to local service engineers?. The software system is easier to handle, but it would be nice if there were a list of hardware notes as well. The collection of e-mail messages on this list is useful, but it can be hard to find a useful comment that is tucked away in a corner. Perhaps we should club together and employ someone to systematise and index our information?. Can anyone volunteer?.

In good days, however, on the same >crystals and standards, the calibration come out good on the first try ... Some of you may have heard this true Camebax story before... Several years ago we had a problem making the calibrations "stick". We would carefully calibrate Na, Mg, Al, and Si all on TAP1. Then, when we checked the fresh standardization of Mg by performing a full analysis of the standard (a Mg-rich olivine), the Mg would be horribly off the mark (ratio of 1.03 or so). To try to understand this, I set up another dummy procedure using Mg, Al, and Si on both TAP1 and TAP2. (I was only interested in collecting k-ratios; the concentrations calculated from the input of two spectrometers was meaningless.) With the test procedure, we had no trouble standardizing Mg, then analyzing the Mg standard. No more 1.03 ratios. Both spectrometers worked fine. After much head scratching, I set up a second dummy procedure, this time with Na, Mg, Al, and Si on TAP1 and TAP2. This time we were able to reproduce the problem with TAP1. TAP2 was still OK. The difference between the two procedures was the addition of Na before Mg in the second procedure. There was very little Na in the Mg-standard, thus the count rate for Na was very low, while the count rate for Mg was very high. It turned out that the detector was dirty and had developed some sort of memory based on previous count rates. After cleaning the detector, the problem went away. ============= About Vincent Yang's backlash test on his SX100: Very interesting test. I am used to stepper motors on our probes, with mechanical backlashes taken before each peak and (-) background position. On the SX probes, is backlash no longer taken? It sounds as if the engraved glass slides have theoretically eliminated the need for backlash, though it appears not to be 100% effective in Vincent's case.

However, the important thing is the Bragg angle, which is derived from the carriage position by mechanical means, and in principle could therefore exhibit backlash.

However, on my low milage SX-51 it is a small improvement to take the extra time to perform a backlash so I almost never use it. I have measured spectrometer reproducibility at the half max intensity (counting for 0.5% statistics) and found that using a backlash gives intensities that reproduce within +- 0.6% and without a backlash within +- 1% except for ADP which is a very narrow peak. Measured at the peak position, the reproducibility was equal to the counting statistics for both with and without backlash. john ==================================================================== =========== John J.

The easiest method for this is to have a 0.05 um collodial Si lap right next to the carbon coater so I can buff off the previous carbon coat. Takes about a minute. Clean with alcohol and then a 30 minute bake at 80 degrees C to remove any surface water. We found that without the bake, the more focussed beam on the SX50 would just blow the coat right off sometimes. After several dozen of these buffings we need to use fixed diamond to bring the relief back down. Also use a fast tray rotation in the evaporator and apply the coat over many rotations to even out the coat. Paul Carpenter even measures carbon during oxygen analyses if he suspects that the carbon coat is not exactly the same for standards and unknowns and corrects the intensities using a thin film calculation, however I have found that I get identical carbon intensities if I carbon coat standards and unknowns at the same time slowly and carefully as described. Another observation: never, never use a sputter coater for any quantitative work. john ==================================================================== =========== John J.

Vincent Yang > Lockheed Martin > Yang@snmail.jsc.nasa.gov > It is sad that different matrix corrections give different results, however I have settled on one method that gives excellent results. Read on... OK I hate to bragg (WDS pun!) but I have always used pure oxides when possible as standards. My thinking was originally that at least the composition of Al2O3 is known exactly. However, since the use of pure oxides really stresses everything in both the hardware and software, I figure that if the standards agree with each other then I can be sure that the unknowns are going to be good also. My typical standards for silicates are MgO, SiO2, Al2O3, TiO2, Fe3O4, Cr2O3, MnO and albite and orthoclase for na and K. Running these and additional silicates (fayalite, diopside, etc.) as secondary standards and analyzing for all elements (the default behaviour in my software) in each standard I get variances (relative errors) around 0.5% or less for the major elements Si, Al, Fe and Mg. This was true on these standards on my old SEMQ (52.5) and much to my relief it's also true on my SX (40) with the same standards. I should state that I have never "tuned" a standard composition, it's either the published value or calculated by formula stoichiometry in the case of pure oxides. I also never have seen high totals that others report in garnets and olivines. How is this possible? Well I attribute these fine results to several things: 1. The Si/Al fluorescence is usually calculated wrong in most matrix correction methods. The CITZAF Phi-Rho-Z based correction from Cal Tech by John Armstrong I use in Probe for Windows seems to handle this correctly. In fact the JTA Phi-Rho-Z seems to work just about perfectly on eveything I throw at it. 2. The MAC for Mg ka in Fe (from Heinrich) is too high by about 20% according to Henke (1988). All commercial programs that I know of use the Heinrich table. This is a major cause of high totals in garnets and olivines. Other Heinrich MACs are also suspect. I can supply this Henke table to those interested by the way. 3. Some users are not careful enough in adjusting the PHA to center the pulses. This causes problems when the count rates change from std to unk. 4. Deadtime is not as large an issue on Cameca microprobes with the "enforced" deadtime electronics in the amplifier, but it should be measured nonetheless as I have found that several of my detectors needed to have the "enforced" deadtime set to 4 us to completely mask the "intrinsic" deadtime of the system. If everything is setup right it's amazing what the probe can do. I recently schocked myself during a run of mullite and Al metal joins and found that, using Al metal as a primary standard, I could measure al in Al2O3 perfectly. By the way, this was not possible with the narrow slits on my SEMQ. But in the SX with no slits it worked. Analysis of oxygen requires much more work including use of recent empirical MACs from Pouchou and Bastin, in addition to Bastin's APF factors. If all these factors are utilized correctly I find that oxygen analysis in silicates is actually easier that Mg and Na. john ==================================================================== =========== John J.

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Thank you to those who answered my call. I have sat on an answer, also to let my irritation subside a bit. Irritation both with myself and with Cameca. With myself, for failing to rearrange my assumptions as to how things actually work. I routinely delete the previous calibration and, like Todd and others, I 'inires' after every and each use of a Quantiview function, which is probably not always necessary, but certainly is prudent. Storing a 'declaration' after a calibration I perceived more like a magical ritual than as a necessity, and the fact that I was driven to do it only on occasion seems to suggest that the SX50 is ultimately a good instrument. I have rechecked the Quantiview manual and although nowhere it is stated that one should NOT re-declar after a calibration, everything suggests that one should not have to. I guess that is also why you have referred to it as a 'bug'. Which brings me to my irritation with Cameca, for leaving me and others in the dark, unnecessarily and on such trivial issues. It appears that quite some thought has gone into the formulation of the service contract structure, so I cannot think that institutional indifference on other matters is due to laziness. But I have lost hope that one day I might understand the rationale for it. From ???@???

If you enter esewx immediately after an inires, you will see a 'clean' table with stage and spectrometer limits, as well as xtal definitions. If, after some use of the probe, you enter esewx again, you may see two columns of numbers where none were before. I asked for a key to interpret them, but I am told one is not available. It appears that using the software leaves a trail of detritus in the buffers(?) which at times interferes with the proper functioning of the commands.

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas A quick test of our sx100 spect.regarding the backlash problem shows that the peak counting rate drops about 0.7 - 3% if I move the spect downwards to the peak position; and there is no counting rate change if I re-approach the peak position upwards. However, the counting rate dropped as much as 15% on sp. #1. Apparanetly, this sp. has a "loose" xtal assembly to induce such a bad backlash. The good news is that such cps drop does not happen in quantitative analysis regardles of different spectr movement arragements. Obviously the sx100 Qt programs include the backlash" subroutine in peak move; otherwise I would see a 15% drop of pk counts on sp #1 if the sp zeros in the pk position downwards. (I'll check the source codes to confirm this.) Originally I though sp backlash function was not necessary on sx because positioning is based on encoded slide. Still, similar test can help us to identify any sp. that is developing a "shaky" problem. It might be useful to record such backlash-induced count drops on a routine base (once a month?) just to monitor the sp performance change. S.

We have the same crazy problems with our SX51 (No. 500) in Heidelberg. Since the installation (April 1994), these problems have remained. Cameca could never solve them. Immediately after calibration the i.x./i.std for Mg, Al or Si on TAP can be changed to be 0.98 or 1.02. One day it is good, the next it will be bad and you have to recalibrate several times, getting different count rates and/or different Sin-Theta each the time. It drives you crazy, when you calibrate and then try to analyse. I never have these problems with PET, it is always with TAP. After installation of the machine, this problem appeared especially on the TAP crystals. We tried everything to solve the problem, we even exchanged a complete spectrometer. Cameca always told me that I am the only one having these problems. It seems, that even more customers have similar problems. It is not just the recent discusion on "spect. backlash", that points to these problems. I think, that the mail on "ROM peaking" (sent by John. J. Dononvan on 1.5.1996) possibly reflects the same or a similar problem. This should be solved!!! I worked on an older SX50 (No. 404) in Karlsruhe and did not have these problems at all. Constant i.x./i.std for several months on Mg, Al and Si made me be a happy man. This is different on my machine in Heidelberg. After 1 year of working in Heidelberg I got a new (extended) Spectrometer No.5. The data and the reproducibility on this spectro were good. On my spectro No.5 I had fantastic results (on Si and Mg) for for a period of about 6 months. I thought the problem was solved. Then J.M. Peneau from CAMECA changed the logical board and the Power board of this spectro when we had some trouble with the Spectro-motor. I think, he did nothing else (I'm 90% sure). Since that time the problems have reappeared. I know that it does not seem to be logical, but this is reality. I think the different comments on this topic, which appeared in the mail during the last three days, did not bring the final solution. I can not believe that the problem in my case is the detector (as Carl Henderson wrote) because we did not change anything with the counter when the problems reappeared. We did not change the gas either. It is not the temperature in the room (as Todd wrote), because I have absolutely constant temperature in my room all the day. So what is the solution? ____________________________________________________________ ___ The following text is just for the people of CAMECA (France): Mr. Staub, as you are a member of the sx50-users-list, please forward all the mail concerning this problem (which drives me absolutely crazy) to Michel Outrequin and the After Sales Service (Mr. Haussiere, Mr. Van Pevenage). I am finally glad (?am I really?) that other customers have found the same problems with the machine that I have had for a long time. The After Sales service and/or the production should think about this problem. My personal opinion: How can I recommend a microprobe that causes major problems with calibrations and reproducibility?

We have an old SX-50 and have always used a software analysis system which is probably more robust than Cameca's. From the discussion, it may be very considerably more fault-tolerant, but we have no evidence on how much better it is. Our WANUSX analytical package was designed by Nick Ware at ANU, Canberra, for the Camebax Microbeam and adapted for the SX-50 here. It includes some primary design features which shield us in part from some of these problems. I mention the features here as it has some bearing upon the design of future generations of probe software, and as well it offers people troubled by spectrometer reproducibility problems a viable alternative. People are welcome to change to our software, but our experience is that most prefer to stay with the manufacturer's software. We have chosen the route of using simple and easily-modified software. This means if there is a problem, we either fix it, or live with it, but we do not complain to Cameca. This can be an advantage in some circumstances. (We do have the option of asking Nick Ware for advice, and getting him to install upgrades and options if we can't) 1. WANUSX routinely collects data by integrating across the top of the peak, using 5 points which are each spaced say 5-10 units apart, depending on the width of the peak on the standard. This has two significant advantages (and some disadvantages). A. It integrates over the top of the peak, and hence spectrometer angular calibration and stage z-focus errors have far less effect. This is useful for long runs, for instance a 24 or 36 hour run over a weekend, and it requires a lot less precision of the spectrometers. B. While integrating, it also can tell for each analysis if the peak has moved from the expected position and by roughly how far. It does a peak position determination from the five points, using the data it has already collected. We have not gone the next step of getting the system to update the expected peak position, as there seems no need, and for random focussing errors, it would not help and may make things worse. Our data printed for each analysis has the deviation of each significant peak from the 'expected' position, so one can look back over the run to check for any shifts in apparent peak position. We do not often see worrying peak shifts, but that may mean we do not always worry when we should. We have seen apparent shifts of Mg on TAP, relative to the Si peak. This seems to happen in jumps, and it often seems to go back at some stage. I presume if our software was less tolerant, we would have had to look at it more seriously. 2. WANUSX routinely does a backlash correction, that is, it drives to each position from the same direction each time (upwards in spectrometer terms). I noticed this function recently, and was going to disable it as I thought it was not necessary on the SX. However, I have left it in, as it is easier than removing it, and because of the recent discussion on backlash. I may make it optional as John Donovan does. It may be more important as the spectrometer mechanisms wear. However, when there is a low background done, then the peak is approached the same direction each time anyway. The main disadvantage of the WANUSX strategy is the extra time required and possibly more wear on the spectrometers and motors. WANUSX has a minimum count on an element of 20 seconds. This is split 10 seconds total on the peak, and 10 total on the background. This means seven individual counts, 5 seconds on each background and two seconds on each of the five points across the peak, low-bg, peak-1, peak-2,,, peak-5, then high bg. There is an idiosyncracy of the SX50 design that it takes it about half a second to move a spectrometer 1 unit and to count for 1 msec. That is, there is a very considerable time overhead added to each operation. As we use more operations, (7 move/count per element rather than 3) we pay a time penalty over the standard SX software, This penalty is considerably larger on the SX than existed on the Camebax Microbeam, for instance, as the SX-50 is very slow. I hope the SX-100 is faster. (any volunteers for a comparison test?). We are happy with the compromise. We collect very reliable and fault-tolerant data, but it takes us a bit longer per analysis. We also have a number of advantages in the way data are archived, layout of method files, and so on. WANUSX is simple Fortran code and can be relatively easily modified for local preferences and circumstances. It also has a simple high-level library which makes it very easy to write special-purpose programs, such as spectrometer test routines for instance. WANUSX is ideally available to others, but it currently only runs on PDP-11 SXs, but can easily be modified to run on Sun SX-50s. We know this is relatively easy, as our CSIRO-Trace routine runs on both platforms. I do not know how different the SX-100 is from the SX-50, but I suspect it must be relatively easy to convert programs if they are not directly transportable. I will be happy to provide information to interested people. I would still like to pool the resources and information about the various probe programs and assist Cameca with broadening their software base. For instance, there are a number of different systems which can run on the SX. However, most people have available only one. It may be useful if people had more of a choice with a factory probe. This way Cameca could cater for the people familiar with the existing system structure, while trying out systems based on other concepts. At the moment, Cameca are probably tied into an incremental development strategy which tries to retain much backward logic/structural compatibility while being innovative at the same time. This is inherently very hard. Any ideas, feedback?

Yes, I quite agree that user adjustable servo loop tuning parameters would be quite useful, however I was told by Sam Pindrys that these parameters are burned in the ROM and cannot be changed. This is sad because I wouldn't mind SLOWING DOWN the stage on my SX-51. My old probe with the Advanced Microbeam hardware had totally "tweakable" servo parameters. Is it possible to adjust these servo parameters on an SX-51???? john ==================================================================== =========== John J.

To this end the following test procedure has been applied to our 7 year old SX50. The peaks used are: MgKa (TAP), CaKa (PET), and CuKa (LiF), which are all at around 38000. The beam current is chosen to give 20000-30000 cps on each peak, so that high statistical precision can be obtained with a 10 second count. The spectrometer is set to the half maximum point on one side of the peak. A series of counts are then taken after offsetting a large amount above and below (RMOV 10000) alternately and returning to the original side-of-peak position. The slope of the side is determined by taking a few points up and down (RMOV 5) and the spread in the side-of-peak data is converted into an error figure expressed in 'Cameca units', namely sine theta times 10E5. This gives the mechanical reproducibility, which can be converted into peak measurement error with the aid of a plot through the peak region. Only one spectrometer showed a systematic hysteresis effect, i.e. intensity consistently dependent on whether you approach from above or below. The spread in side-of-peak data was 2.5%, which converts to 1.5 spectrometer units, giving an estimated error of 0.2% in peak intensity. The other two spectrometers were better, the side-of-peak data showing smaller variability, with systematic hysteresis hardly discernible among the random differences, and the inferred setting errors were respectively 0.8 and 0.5 units. Cameca include spectrometer reproducibility among their acceptance tests after installation: I can't recall details, but from the print-out in our files it seems to consist of peak counts measured after offsets above and below, with plus or minus up to 0.5% regarded as OK. This is not unreasonable, though less rigorous than that described above. A possibly relevant fact is that we use EDS for most major element analysis so our WD spectrometers do not get much wear. One might add that using EDS avoids the worries that a number of people seem to have about reproducibility (it is hardly significant for trace elements), though it is obviously necessary to have EDS hardware and software that are up to the job.

I still haven't had enough hands-on to form any opinions. Thanks for your help. -Jim *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.* James J.

This can be an advantage in some circumstances. (We do have the >option of asking Nick Ware for advice, and getting him to install upgrades >and options if we can't) I know this situation well having written my own software for the SX-50 running under Windows. If something doesn't work the way it should or I don't have a feature I want, then I have no one to complain to but myself. On the other hand, no one makes you work harder than yourself, so every feature I can think of (in addition to many suggestions from other users) has been incorporated, so I now have exactly what I want in EPMA software. Being in control of your own destiny is a two edged sword! [some stuff deleted] >1. WANUSX routinely collects data by integrating across the top of the >peak, using 5 points which are each spaced say 5-10 units apart, depending >on the width of the peak on the standard. > This is an interesting approach! My solution to peak position drift is to use an automatic standard intensity drift correction, so that once additional standard intensities are acquired the software will interpolate the standard intensity for any unknown analyses that are "bracketed" in time by the standard acquisitions. This also allows one to view the standard intensity drift over time as these additional standards are acquired. I also apply this standard intensity drift correction to the interference intensities and the MAN background intensities. However, although this feature was essential on my older SEMQ, I have found it to be somewhat less important on my SX-50 due to the newer probe's better stability. On long runs though (over 24 hours) it does help to really nail down the analyses. It will be interesting (based on some previous discussions) to see if my probe retains it's xray intensity stability (reproducibility) as it gets more wear and tear. Perhaps we could all send results of spectrometer reproducibility using Stephen Reed's (or another) specification along with the probe's age and estimated milage. My own spectrometer reproducibility test script I sent to everyone. It was called RATIO.TAS, but would need to be modified slightly for those with less than 5 spectrometers. I can send it again if it would be agreeable to everyone. Stephen : Do you also have a saved .TAS script everyone could run (what about SX-100 users?)?

This is one thing that I really noticed after I moved from my PC based ISA bus servo hardware to the SX and it's DRV11 interface. On my probe (with a Pentium 133) it takes about 3 seconds to actually start moving a motor after the command is actually given. On the Advanced Microbeam hardware it was virtually instantaneous. Even through the SXLocal interface it's the same. Does anyone actually know what the SX is doing during this time?

If so, any simple serial printer will work. I am using an old Zenith (!) that I got at a garage sale for $50. Much better than the DEC LA-something that always jammed. Several nice Okidata 9-pin dot matrix printers are available with serial ports, and I think most of the HP laser printers have serial ports as well. Normal serial cabling applies, and there are no drivers needed. Just set the baud rate for the DEC port and the printer the same. Ken Severin - Fairbanks. You could really kludge things with a serial to parallel converter box, then use just about any dot matrix printer ever made. From ???@???

With respect to your = problem, I used the equivalent crystal on a JEOL microprobe (and earlier = on a ARL-SEMQ) and was able to analyze boron in silicates and oxides = without too much difficulty.

In terms of your compound, I would suggest you analyze at 10 kV and = measure the Ge L line. Boron yield is relatively low and drops off = above 10 kV due to overvoltage effects. I do not think the O 3rd-order = K line is a big problem (I tested for this) and the sixth order Ge line = should be suppressed by the LSM crystal (at least that's what is always = claimed).

We're quite happy with the Lexmark as it can take up to 1000 sheets of paper and has not gone down in >2 years. Compatibility is not an issue since CAMECA finally provided postscript output for all its programs. My view is that a printer that supports postscript is the only type to buy in a networked environment as it (postscript) is the defacto cross platform output, I should say that the LExmark also services a small group of SGIs, several MAcs, as well as 1 or 2 PCs.

Vac is 2 -4 in chamber, but getting "Ion Pump Vac Threshold Problem Message" and it is bouncing between 2 -4 and 8 -5. Hopefully it will straighten out by tomorrow morning. I realize now that I should have an alcatel diffusion pump manual. I have 2 rotary pump manuals. Presumably one manual comes with each pump, so I would appreciate receiving a manual for the dif pump. It surely will come in handy, as I now realize that I cannot assume anything about the dif pump being trouble-free. Thanks. I still am confused: is my diffusion pump an "old model" (as implied by Stefan's statement that the heater on it -- a flat donut -- is the old model that has been replaced by the new and improved one you sent) -- or is it a "new model", as implied by the fact that it has a bottom cover plate that apparently other models do not have?? Or is it a hybrid? Also, the diagram(s) I received were confusing/incorrect in showing the attachment of the wires to the terminals on the connector. The page "9.1, crystal 62-202 diffusion pumps" xerox shows BOTH wires attaching to the 2x terminal, which I assume is wrong! I reattached the wires to the original leads, one of which goes directly to the connector, and the other goes up inside of the conduit. Could be clearer. I had to get some spade connectors that had the flat male connect on one end and bolt holes on the other, and then use bolts and washers to connect to the original leads, and then attach the male spade to the female on the new heater. I will draw up a diagram and fax it to you.

You may want to download the latest version, here are the instructions. john To install the Probe for Windows upgrade please read the following directions. 1. Using anonymous FTP access perry.berkeley.edu. Type "anonymous" for your user name and give your user ID as the password. 2. Change to the outgoing/donovan sub-directory. 3. Using BINARY transfer mode, "get" the following file : PFWNEW.ZIP If necessary also get the PKUNZIP.EXE file for extracting the files. 4. Copy the .ZIP file to your Probe for Windows directory (usually C:\PROBEWIN) and then change to the C:\PROBEWIN directory (type "cd c:\probewin"). 5. Unzip the PFWNEW.ZIP file onto your hard disk using the command "pkunzip pfwnew -o". The "-o" parameter directs the pkunzip program to overwrite existing versions without prompting.

Our SX50 dif pump heater died at an apparent age of 3.5 years. Yesterday I removed it and installed the replacement that Sam sent. The job, to say the least, was not straight forward for several reasons, particularly the change in design of the electrical connections from the old heater to the new heater model. (Add to that a new? bottom plate hiding all the parts of interest) I had (erroneously) assumed that the dif pump would not be something I'd have to worry about, at least for a good many years... I would be interested in knowing what other peoples' experiences have been, particularly re the life of the dif pump heaters. Have you ever had to replace the heater? After how many years of usage? Any other problems with the dif pump to be watched for?

My replacement was fairly straight forward, with no real difficulties. I did note that when it blew, it tripped the breaker switch at the distribution sector, and I had no power anywhere to the SX50.

However, over the last 15 years or so that we have had our Jeol SEM, the heater had to be replaced at least three times, to my knowledge. Short of having the wrong heater for the particular pump used (for instance, I wouldn't expect that changing the oil type should have such a dramatic effect as reported by Michael Shaffer), I think that the main factor affecting the heater's life is its 'planned' quality, plus the manufacturing quality. I have had experience with split furnaces, at times with fully exposed windings, and they lasted for a few years, despite quite harsh use. From ???@???

Regarding your diff pump problem - I have had no problems since it was installed in 1989. I was thinking about your feldspar problem (high totals). I am sending you a chip of the Eifel sanidine which I use for Si,Al and K. I use Amelia albite for Na and a Diopside standard for Ca (15kv 20na size 5). I will also send you a paper written by one of our grad students regarding feldspar analysis which includes Eifel sanidine.

I understand that they dominated the meeting with formal presentations. I just spoke with Andy Davis who mentioned that both of you had a chance to demo the new software at the meeting. I for one would be grateful for hearing your reactions to it. I am considering dumping Cameca software and going with SAMX which I demoed at Oregon State two weeks ago. I have been waiting for the new release to make my decision but that has now been delayed until the end of October, according to Andy, at the request of the users (?) so it can be tested in a US lab. I would really like to know whether they made a major improvement in their product or are still beating life into an old horse. The SAMx people insist that Cameca has not changed the core of the program, just the appearance. Is this true? Hope you are having a great summer. Mike From ???@???

Yes they did dominate the meeting, though I think much less than they had originally intended - Andy and Pierre Staub visited me a few days before the meeting and I impressed upon them that none of us were interested in glowing reports about new features, that we were upset about long standing bugs etc, and that that and users questions had to be key parts of the meeting. They did dominate, though, that was perhaps no one of us had attempted to organize the agenda ourselves independent of them. That is what future meetings should be, certainly. I will propose that we try to hold a half to whole day meeting before or after one of the annual meetings of MAS, AGU, or GSA, with some reports, technical talks as well as a bitch-at-cameca session, etc. The question of course will be which meeting/s. (The environmental SEM users had one such meeting the day after the MAS meeting, a good model I think. Eric Doehne, a new SX100 users, is involved with that group and hopefully will lend some help) I looked at Cameca's revision of the software to run the SX50 (called SXN50) (I did not drive the SX100--maybe I should have, but I didn't want to play with the dedicated XYZ, mag, etc controls -- might make me angry that I didn't have them, or something like that). I also checked out SamX -- and Donovan's software which the unofficial word is that Cameca will be offering sometime soon. I was very favorably impressed by SamX, less so by Donovan's (probably because there is much in common between SamX and Cameca, so it made sense easily, whereas Donovan's was like a totally different language that I had to learn from scratch). I will write up more details, but I think Cameca has fixed many/most of the bugs we had reported. The OpenWindows is a much nicer interface and no more of the fucking right click on this and left click on that. I could not, however, determine whether everything I desired was implemented, a key thing being that all the data collected is easily transported across platform as tab-delimited data. Pierre Staub assured me that it was. And the buttons seemed to be there. But on the demo machine (separate from the one hooked to the SX100, there were few if any data files to play with). While I like Pierre and think he is a benefit to both Cameca and to us, he doesn't hold ultimate power over software programmers assignments, to get things done. My feeling is that I am willing to wait a couple of months and see what the release brings, before I begin serious thoughts of spending $12K or whatever for SamX. But if it is not all that I expect, I will seriously consider SamX then. (I told Andy, and I think Ed concurred, that they were nuts to release the new software next month without any labs here giving it 2-3 weeks work out -- so that is why they're saying October now. I think Ed will be testing it out, and so he can give you more info as that progresses.

I too have wondered how honest Cameca is being with us about their future software plans. They have such a poor record. I am disappointed by continued delays in product delivery and in the nature of the products. An upgrade to Solaris 1.0 is silly and, according to my Sun software expert, is a minor upgrade from Sunview and to a now archaic operating system. She feels the next upgrade will be much more difficult than Cameca has led us to believe. This is particularly disturbing given Cameca's slowness in releasing the Solaris 1.0 upgrade. Samx offers both an analysis routine (Xmas) and a imaging package (HiMax). Together they are expensive ($40k). I would probably get both because we have never learned to use Visiview, despite Cameca's promises to offer a course on it. I do not know what Cameca will charge for their software upgrades; we have a contract to get software upgrades for another 8 months, which might carry us through the next upgrade, if we are lucky. I am glad that you put pressure on them to answer some tough questions. Andy Davis called me today and did not mention any of the software options that you mentioned. Who is your unofficial source for the software marketing of Samx by Cameca? It truely makes sense to me, so I doubt that Cameca will do it. An old Cameca salesman represents Samx in the USA now, Bob Hessler. I hope you will post something soon on the meeting so those of us who did not make it can enjoy the update. My preference for future SX50 users meetings would be the fall AGU, which I always attend. Where will the next MAS meeting be? One last question. Do you get printer electronic jams that freeze the printer and require rebooting? We get about one a month with no particular pattern to them. It is annoying. Andy Davis gave us some advice but it does not work. this is another reason for us to switch from a Sun.

Am I the only one to have this, or have you all learned how to work around it? The problem is that, on average, 1-2 times a week, the communication link between the local window and the SX microprocessors is lost. You can type all you want in the local window, but the SX isn't responding. If it happens to me, or I am around, I go through a standard list of steps: Ctrl P - never works; log out, log back in - almost never works; reset - almost never works; software reboot of Sun - works some times; reset the 68000 wds board, then reset on front - works most of time; rarely I have to turn off both eds and wds power supplies. When it first started, Cameca told me to check the ttya sx/sc cable was plugged in securely to the sun; originally that was a probably but has never since been a problem.

Too bad about Cameca and Samx. He has a great product and an even better attitude about working with customers.users of his software. He has no love for Cameca but did not talk stink about them to me. The biggest group of Samx users are in FRance, which says alot about Samx. I am not crazy about Donovan's software from what little I have seen. It will be curious to see how things develop for probe software. I am dumbfound that you never have printer problems. It is our main non-hardware problem. We must have got a bad installation, although it works most of the time. Ed Stolper wrote the GAS article. I gave him some suggestions but he did 90% of the writing. He is an amazing guy. Where in the Aleutians were you? I hear that country can be nasty weather-wise. I met a fisherman who works there in the spring each year and he says it can be really bad and he was no sissy. Another geology expedition went to Adak and lost most of their equipment during a storm and had to leave 3 days into a 6 week field season.

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Our SX-100 similarly loses the communication link between the SUN and the microprocessor. The problem occurs less frequently now than it has in the past, though once a week might be average. Unfortunately, we have not had much luck figuring out the problem either. We just do what you have been doing, reboot the SUN, reset the probe electronics and then bring it back up. Though we can not pin it down exactly, the problem seems to have been worse in the past with different versions of the software. It seems that somehow the memory allocation in the SUN is not properly released for reuse if windows are not closed with the menu exit command. When we close all windows in the menu fashion the frequency of lost communication problems decreases. Real or coincidence? Craig Craig S.

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Status: RO Is the REMO key or function entirely eliminated from your custom keypads? There is a fix possible by writing a byte to the microprocessor. When doing a reset, do you wait for the "SE" to appear at the bottom of the monitor before hitting return? If you fail to wait for that label to appear, it interrupts the reset process for one of the microprocessor boards. I think I got "second micro not available" errors, but don't remember for sure. The fix usually required turning off power supplies and removing circuit boards to bleed the charge out of the memory. When Cameca informed me of the error of my ways, the problem disappeared.

Thus, the product they are telling us will be released soon for SX50 users is full of problems and is not "mature". Why am I not surprised? I really hoped that Cameca was telling the truth this time but I should have known better. I think I will be going with SAMx unless I hear something to convince me otherwise. I will wait until October to make a final decision. I will be interested to hear Ed Vicenzi's commments on it if he is a beta tester. Regarding your not having printer halting problems, my Sun person asked if you used the print option regularly. She says printer halting is typical of Sun serial interfaces. Cheers, Mike From ???@???

After a common standardisation on a danburite (for B Ka1 and without any special care), I found during analysis that minerals normaly free of boron apparently possessed a significant percentage of B. Wy did I found boron ? Maybe because the number of counts of the background (offset counts*slope) was too low or wrong. Therefore I began to record small spectra around the peak position of B Ka1 on different standards free of boron and at the boron position to count the background intensity. The following experimental results, sorted by atomic number were obtained (on a PC3 of regular size at 15 KV and 20 nA) : Morganite Z = 10.2 73 c/s MgO Z = 10.4 64 c/s Al2O3 Z = 10.6 63 c/s Kayanite Z = 10.7 63 c/s Rutile Z = 16.4 117 c/s Fayalite Z = 18.7 104 c/s Cr2O3 Z = 18.9 108 c/s Fe2O3 Z = 20.6 118 c/s MnO Z = 21.2 103 c/s Cu2O Z = 26.7 95 c/s As2O3 Z = 26.9 96 c/s Barytine Z = 37.3 305 c/s CaWO4 Z = 51.8 179 c/s I have read many publication on "background", notably "Bremsstrahlungsuntergrund massiver Proben bei der Elektronenstrahlmikroanalyse" from J. Bocker and Th. Hehenkamp in Mikrochimica Acta [Wien], Suppl.7, 209-230 (1977), and much more important "The Calculation of Background in Wavelength-dispersive Electron Microprobe Analysis" from D.G.W. Smith and S.J.B. Reed in X-Ray Spectrometry, vol. 10, 198-202 (1981). Using the different formulae given in the latter publication, I computed, for each of the above standards a theoretical background intensity to which I applied their specific absorption factor calculated at boron energy (192 eV). Using a scale factor of 0.74 the following computed background intensities were obtained : Morganite Z = 10.2 62.3 c/s MgO Z = 10.4 63.9 c/s Al2O3 Z = 10.6 63.5 c/s Kayanite Z = 10.7 64.6 c/s Rutile Z = 16.4 117.1 c/s Fayalite Z = 18.7 102.3 c/s Cr2O3 Z = 18.9 107.7 c/s Fe2O3 Z = 20.6 118.8 c/s MnO Z = 21.2 103.1 c/s Cu2O Z = 26.7 94.2 c/s As2O3 Z = 26.9 94.7 c/s Barytine Z = 37.3 305.8 c/s CaWO4 Z = 51.8 228.5 c/s With the exception of the first and last values (maybe due to one or more wrong mass absorption coefficients), correlation between experiment and theory is pretty good. Therefore, I applied the same method to all of the analysed minerals and everything fitted better : no more boron in silicates and oxides normaly free of boron - but happily boron still present in borates ! Subsequently, I have not had the opportunity to test this method further.

This means that any change in the Fe concentration of the sample, will change the relative absorption for the La/Lb lines. It is of course possible to correct the wavescan for absorption and that is exactly what must be done.

Hello Mati, I can't help you with the identity of the strange intermediate peak that you have found, but I am aware of some more modern literature on determining Fe2+/Fe3+ ratios by EMPA. One study by Hofer et al uses the shapes of the L-band peaks, and another study by Lattard uses oxygen contents. I have included both references and abstracts below. I am surprised that at least the first of these didn't turn up in GEOREF. Regards, Larryn Diamond Hofer H. E., Brey G. P., Schulzdobrick B., and Oberhansli R. (1994) The Determination of the Oxidation State of Iron by the Electron Microprobe. European J Mineral 6, 407-418. Abstract A method is described which allows the determination of Fe2+/Fe3+ ratios with the electron microprobe by analyzing the FeLalpha and FeLbeta X-ray emission spectra. We use the ratios of intensities measured on the high energy flank of the Lalpha and the low energy flank of the Lbeta peak. The sensitivity achieved with this ''flank method'' is about 3-4 times higher than with the conventional peak shift method or peak intensity ratio method. The method was calibrated with the iron oxides wustite, magnetite and hematite and was then applied to a synthetic spinel solid solution series magnetite-hercynite (Fe3O4-FeAl2O4) and to several natural olivines (Mg2SiO4-Fe2SiO4 solid solutions). The results obtained by the flank method vary not only with Fe3+. but also with total iron content. A quantitative method for determining the oxidation state of Fe must therefore not only be based on a method with a high resolution but must also include corrections for self-absorption and matrix effects. Our method can be applied, if the bulk composition and crystal structure of the samples are known and working curves are established with similar materials.

Amer Mineral 80, 968-981. Abstract: Microintergrowths of titaniferous spinel and ilmenite have been experimentally produced in the system Fe-Ti-Cr-O by annealing in vacuo at constant temperatures in the range 700-1100 degrees C of spinel + ilmenite assemblages previously synthesized at 1300 degrees C under controlled low f(O2). Depending on the original f(O2) of synthesis at 1300 degrees C, annealing produces three types of microintergrowths: Type I (lowest f(O2): 10(-11)) has rims and trellis-like lamellae of ilmenite as well as small blebs of metallic iron; type II (f(O2): 10(-10)-10(-9)) shows spinel with rims and a few lamellae of ilmenite; type III (highest f(O2): 10(-8.5)) displays both spinel with rims and lamellae of ilmenite and ilmenite with rims and lamellae of spinel. On the basis of microprobe analysis, including precise determination of the O contents, it is shown that the synthetic microintergrowths did not form by a redox process. Rather, the textures represent exsolution caused by vacancy relaxation in spinel (and, for the most reduced samples, in ilmenite), according to the substitution scheme Fe(2)(2+)Ti(-1)(4+)square(-1) (1). The presence of metallic iron in the most reduced samples (type I) results from the shift of the iron saturation surface toward more Fe-rich compositions with decreasing temperature. The rims and lamellae of spinel around and within ilmenite in the type-III samples result from the combination of Exchange 1 and the well-known substitution Fe2+ + Ti4+ = 2Fe(3+). These experimental results show that natural spinel + ilmenite microintergrowths do not always result from either an oxidation or a reduction process. In particular, textures similar to those of type I, which were observed in lunar basalts, may simply record cooling under O-2-conserving conditions. In most terrestrial rocks, however, spinel + ilmenite intergrowths are certainly best interpreted as resulting from oxidation of at least a subsystem of the rock.

Note, however, the following reference on Fe2+/Fe3+ by EMPA: Hofer, H.E., Brey, G.P., Schulz-Dobricl, B., and Oberhansli, R. (1994) The determination of oxidation state of iron by the electron microprobe. Eur. J. Mineral., 6, 407-418. In this work, the authors compare three different methods for deriving 2+/3+ ratios including peak shift, peak area, and intensity ratios of the flanks of Fe Lb and Fe La lines using TAP at 10 KV.

That worked out very well. However there wasen't much material. I used that to confirm the Rb present in the MAS x, y, w glasses made by Corning had half the reported Rb present. The MAS glasses are great for checking but the Rb L alpha peak is so low compared to the Si peaks that peak seeking "gets" the wrong peak. I still use the MAS glass for a standard but I have to "amov" the spectrometer to the correct peak position for the Rb line when doing "calstd" after the peak is sought. Measuring backgrounds is a whole other story but we do analize for Rb and are happy with the results, Regards, Todd Solberg, VaTech. From ???@???

I received about 30 responses and list some of them below. My apologies to those not quoted--I picked a random but representative sample of responses. In brief, there seem to be two controls: 1. Crystallization of Fe in solution in pumice glass into extremely fine "flour" magnetite during welding. 2. Elimination of thin bubble walls, which scatter light. I accept both of these explanations and suspect that #1 is dominant. Clearly scattering is part of the story but cannot be the whole story, or else window glass would be black! If you would like to see the entire list of responses (about 40K of text), drop me a note and I will email the file to you as an attachment. Many thanks, Allen F. Glazner Department of Geology, CB# 3315 University of North Carolina Chapel Hill, NC 27599 USA 919-962-0689, fax 966-4519 http://www.geosci.unc.edu/web/ ***CRYSTALLIZATION OF FINE MAGNETITE*** This answer was given in perhaps the most obvious place imaginable, Ross and Smith's classic USGS Professional Paper on ash-flow tuffs. Joy Crisp pointed this work out and had this to say: *** The best writeup on obsidian color that I could find is in the section titled "Indices of Refraction" in a USGS Professional Paper #366, by C.S. Ross and R.L. Smith (1961) "Ash-flow tuffs: Their origin, geologic relations, and identification" On page 45, they say: "The collapsed pumice fragments shown in figure 1 appear black in the hand specimen. Under the microscope this glass is nearly colorless while the groundmass glass (red in the hand specimen) is slightly brown. The colorless glass contains magnetite microlites abundant enough to permit a perfect separation from the nonmagnetic groundmass. The presence of magnetite microlites in the colorless glass is also observable under the microscope. In this glass the iron that was originally in solution was reduced to magnetite and segregated into distinct granules by reactions that took place during the collapse and welding of the pumice fragments. The elimination of part of the iron from solution in the glass and its collection as discrete microlites of magnetite has lowered the index of refraction of the colorless glass below that of the brown glass." *** Bob Smith himself weighed in on the question with this response: *** When you talk about colored obsidian, you have the additional problem of conveying the notion that in some glasses, black is 'white', and, white is colored! Fifty plus years ago, I was confronted with this problem when I tried to show by index of refraction measurements, that pumice lumps collapsed to become obsidian faster than did the matrix ash, because the pumice retained more water than the ash, hence might have a slightly lower viscosity during welding. Our measurements on obsidians and perlites at that time showed that increase in water content caused an increase in index of refraction. After nearly going blind, trying to see minor differences in indices among pumices and shards and obsidian chips, and sorting out differences caused by secondary hydration, I found that in non-hydrated glasses, the "black" obsidian had a lower index of refraction than did the "white" pumice lumps, and the non-welded shards. To make a still longer story short, I found the index difference to be related to the behavior of iron during the welding process. When the stuff is erupted, the iron(except for magnetite phenocrysts) is in solution in the liquid, and the higher the iron content, the browner it is, but when it vesiculates to form pumice, the greater the degree of inflation, the lighter the color appears. This is an optical effect. However, in the welding environment, the pumice collapses and anneals, converting the iron in solution to disseminated magnetite, and in effect, creating an iron-free glass. This obsidian in most rhyolites is colorless, but appears black for the optical reason you allude to. To test this explanation for any given situation, simply powder the obsidian "fiamme" and a hand magnet will remove the "flour" magnetite. The "white" pumice should only yield phenocrystic, or no magnetite. The formation of the magnetite indicates that most welding in tuffs takes place under reducing conditions. When oxidizing gases are present the process is more complex. Ross and Smith(1961) say a few words relevant to this problem, in USGS PP 366, pages 45-46, and frontispiece, but this is really tangential to your specific question. Arguably, the formation of the disseminated magnetite during welding might be interpreted as the earliest stage of devitrification. However, such assertion complicates the visual classification of the more "massive" devitrification that obliterates all glass. I hope this brief explanation answers your question, but I leave it to you to explain the phenomenon to a layman. Best wishes , Bob Smith. *** Kathy Cashman added: *** (1) Charlie Schlinger did some TEM work with Dave Veblen in the mid 80s looking at submicroscopic crystallization of obsidian. Charlie was interested in what was carrying the magnetic signature, but through that became interested in different obsidian colors. He found that the color was, indeed, related to very small (~ 100 angstrom) crystals of iron oxides, etc... as I remember, he speculated that very local variations in oxidation state could lead to the precipitation of different oxide phases (hence giving rise to different obsidian colors). (2) As to why pumice isn't black ... a couple of thoughts based on some recent work that I've been doing on the color of pumice. Cynthia Gardner (CVO), Tina Neal (AVO) and I have been working on textures developed in pumice from the 1992 eruptions of Mt. Spurr, Alaska. These eruptions produced deposits that showed an abrupt color break, changing uupward (in each eruptive sequence) from tan to gray. The transition is NOT the result of a compositional change, but instead reflects varying vesicularity and crystallinity of the erupted material. Similar variations in pumice color may actually be quite common in other volcanic eruptions, although often the gray pumice has been ignored (this is my assessment after querying people like Charlie Bacon, Rick Conery, Dan Miller, etc.). Always, in our experience, the difference between gray and white pumice is the presence in the former of microlites. While plagioclase are commonly the dominant microlite phase, very small oxide crystals appear ubiquitous, and probably generate the gray color. We suspect that the microlites crystallize in response to degassing, and are currently working to understand where and how rapidly that occurs. However, this is consistent with obisidian being both degassed and microlite (or nanolite!) -bearing... *** Gail Mahood noted the effect of fO2: *** The place where microscopic inclusions control color of obsidian in the eastern Sierra is, for example, at the south coulee of Mono Craters, where there is obsidian streaked red-brown and black. The red-brown streaks are former zones of vesiculation that were welded back together on further flow. Vesiculation and reaction with the atmosphere at high temperatures results in oxidation of the Fe to produce hematite and the red-brown color. In dense obsidian, Fe controls color: red as above; high concentrations of Fe in magmas with low fO2 lead to the dark green color characteristic of strongly peralkaline obsidians; very low concentrations of Fe, along with low fO2, lead to the very light green, almost transparent character of macusanite obsidians. *** And from Nelia Dunbar: *** Small obsidian fragments (1-5 mm in diameter) are found in most TVZ tephra. The color of obsidian fragments ranges from very light grey to black, and the entire spectrum of shades can be present in a single bulk tephra sample (although in other samples, obsidian will tend to be either grey or black). There is no apparent compositional difference between grey or black fragments from a single eruption, either in terms of major, or volatile component geochemisty. Based on thin section observation, the color of the obsidian appears to be controlled by the presence of very small (submicron) acicular microlites (see photo on p. 131 of above paper, and brief mention of color on p. 132). Whether these are magnetite, or some other phase, I'm not sure. Some of the obsidian fragments are color-banded, and looking at these in thin section, the control of microlite abundance on color is very clear. *** ***SCATTERING BY BUBBLE WALLS*** Several respondents noted that foams tend to be light-colored regardless of the material that was foamed. A favorite analogy was the head on a pint of Guinness--the foam is off-white, whereas the beer itself is dark brown, almost black. A sampling of the responses follows. >From Oded Navon: *** The glass is transparent. When a ray of light enters the obsidian it will travel undisturb except when it meets a black microlite that will absorb it (it may actually be absorbed by a few microlites if partially reflected partially absorbed). When a similar ray of light hits a pumice it will be reflected and refracted by the glass-air interfaces. So most light will be back scattered and the pumice appears white. In the case of reticulite (e.g. the Hawaiian bubble-rich glass) the brown color is because of partial absorbtion of the light by the glass which is of brown color (rather than transparent as is the low iron rhyolitic glass) A good analog for the pumice is a pack of transparent plastic bags. The plastic is transparent, but the multiple interface bags appear white. *** >From Gail Mahood: *** The main reason obsidian and fiamme are black, rather than white, is not because it contains inclusions or chromophores and pumice does not, but because when you look at it, you are looking through a thick section. If you flake obsidian and look through the thin edge of the flake it is very light grey or transparent, just like the pumice, where you are also looking through a thin section, in this case, a thin bubble wall. The same thing controls the color of pumice (holding composition constant). Pumiceous carapace with thick bubble walls, like the stuff that is quarried from the Inyo Craters lava dome south of Obsidian Dome is dark grey, whereas normal pumiceous carapace with thin bubble walls is very light grey. *** >From Brian Hausback: *** I have always ascribed the dark color of obsidian vs the light color of the equivalent pumice as a difference in grain size and reflections of light from surfaces within the media. Obsidian has few distinguishable grains. The translucent, dense, glassy media reflects little light and absorbs most. Pumice on the other hand may also be mostly glassy but the high vesicularity provides an enormous number of reflective surfaces for any incident light....lots of reflections, little absorbtion; therefore it is light colored. A good analogy is the foamy head on a beer. The head on my favorite amber ale is creamy white yet made of the same liquid as the deep-amber-colored beer. The head is simple full of little reflective surfaces of bubble walls! *** From ???@???

I suspected that it might be the current regulating apertures so I ran TBEAM which (for me anyway)is in /home/sx/sun4/test and the results were a downward trend that looked rather worrying. The printed output was as follows: Nombre de mesures effectuees : 360 Valeur moyenne des mesures : 20.091 Derive = 0.190 % Fluctuation : 0.351 % a 20.0 nA avec HV = 15.0 kV Derive THT = 0.050 % I was wondering if anyone else regularly runs tbeam and if so what figures do they expect? There are a whole bunch of tests - does anyone know if there are any other useful ones amongst them as there appears to be no .doc files to explain them.

Output is to ascii files which we read into Excel for plotting etc. These routines use our CSIRO-Lib mid-level library which makes custom programming very easy. I have also offered to assist with the design of special-purpose software where needed. PHASCAN and SPECSCAN are stand-alone programs, so we could make them available independent of CSIRO-Trace, if we get clearance from our admin. Sun and PDP-11 versions are available for the SX-50. They have not been tested on the SX-100 We use them for investigating problems of overlap for trace-level analysis. In particular, there are some idiosyncracies where the presence of first order lines alters the low-energy background in the pha spectrum. This has been observed on several SXs, but not always on all spectros on the same instrument. Spectrum scans with very long count times are also needed for trouble-shooting for trace-element analysis in some cases.

Particularly coming off the recent Minneapolis meeting, there appears to be a growing sentiment for well organized users meeting of several hours duration, (more than can be adequately squeezed into an evening during some conference), with several aspects: -- tutorials on various aspects of the equipment/software -- discussion of analytical techniques for 'tricky' samples -- discussion of hardware/software improvements/modifications -- discussion with Cameca regarding common concerns -- other stuff related to empa and our jobs/research It would seem that the best way to go about organizing such meetings would be to set aside a day prior to or immediately following one of the regularly scheduled meetings that many of us attend (MAS, AGU, GSA) and hold meeting of 4 or more hours to permit the above the above discussions. Certainly the optimal setting would be in a lab with an SX50 (or as we go on, SX100), realizing MAS/MSA meetings where Cameca has an instrument present on the floor present valuable opportunities for such user meetings. It would seem appropriate to begin discussion amongst ourselves about venues. FYI here are the upcoming meetings MAS (August) 1997 - Cleveland 1998 Atlanta 1999 Portland AGU (December) all Fall meetings in San Francisco GSA (October) 1996 Denver 1997 Salt Lake City 1998 Toronto 1999 Denver There also is the need/sentiment for having meetings that are multi-disciplinary, which the MAS meetings certainly are; on the other hand, there are many geologists who tend to attend the AGU or GSA meeting. Do we want to shoot for 2 full users meetings per year (MAS plus AGU or GSA)? Is there enough interest to do that? What do you think? I would think we should be flexible regarding the location: certainly San Francisco is attractive with SX50/51s at Berkeley and Davis; some of the GSA sites also have SX50s (SLC and Toronto). So the venues are optimal. Please give your opinion and suggestions. Specifically, 1) would YOU spend an extra day at one of the national conferences in order to hold a longer SX-users meeting with a technical session? 2) Which one/ones of the upcoming conferences in 1996 and 1997, do you plan to attend? Would you spend an extra day at this meeting for an sx-users meeting? 3) Do you have any specific topics you would like see discussed? Give a presentation on? ===================== John Fournelle Electron Microprobe Lab Internet:johnf@geology.wisc.edu Dept of Geology & Geophysics Office: (608) 262-7964 University of Wisconsin Lab: (608) 265-4798 1215 West Dayton Street Fax: (608) 262-0693 Madison, WI 53706 Amateur radio: WA3BTA/9 http://geology.wisc.edu/~johnf/sx51.html "The first rule of all intelligent tinkering is to save all the pieces."

Response: they are doing very well on the ion probes; making less so ("a modest profit") on microprobes. Have sold a bunch of SX100s ; important is the Japan market where LOTS of probes are sold (by guess who). Cameca has allied with a Japanese dealer. Safarti asked for suggestions for innovations to the microprobe. (something about field emission gun???) Claude Conty (Cameca Instruments, Inc.): --Dominque __ is the SX project manager in France -- Cameca trying to improve communications within company and with users. Bill Dempster is the person who should be contacted for hardware problems (camecabill@aol.com). Software probllems should be sent to software@cameca.fr with a copy to Bill Dempster. --If users need to reach someone at Cameca in Connecticut on the phone, the best method is to hit 0 after connecting, get the operator who will page the person. Messages can be left in a persons voicemailbox, but to get someone immediately if they are there, go via the operator. Question from floor: Why is Cameca hiding the bug fix reports on the computer in binary? Response: doesn't know anything about that. Not trying to hide anything. --- Upgrade of software for SX50; cameca has revised the software for SX50 to be almost the same as that running on the SX100, under Open Windows. Is called SXN50 software. Currently running under Solaris 1, to be released in late September [ this has been set back to later -- my guess is November??, to allow a US lab time to test it out before releasing it].Will need Sun 4 or higher model. But Solaris 1 not work on newest Sparcs - so a newer version to run under Solaris 2 will be released January 1997. --Question: cost of software? No charge if you have full service contract; $1500 for others. Question: does this cover a visit for installation and training? No, that would be additional. -- Regarding Cameca sticking with UNIX or going with PC: there is no question that they are committed to UNIX and SUN; however, there is nothing to stop networking PCs and Macs to the Sun and running stuff on them. Pierre Staub: Bug Fixes and corrections in new software [NB. Ed Vicenzi will be sending out a memo regarding software changes] I. Problems in Quantiview A. Declaration 1. Before max of 50 labels, now 400 allowed 2. Label names can be enterred now before appending calibrations B. XYZ 1. Protection message to prevent overwriting existing data 2. Easy way to edit xyz files; interactive, allowing movement to designated position to check it. 3. Automatic storing of positions as soon as enterred 4. Stage scan: comments can be added after point selected C. Analysis 1. Difference - now allows elements other than OXYGEN 2. Show conditions: shows correct calibration dates [there maybe still some question about this] II. Image acqusition - common panel for CIAP and FCIAP 1. No longer comes up with some stored spectrometer configuration - reads the current instrument setup 2. One frame acquisition properly stored 3. All images stored as soon as acquired (YEA!) 4. Protection message to overwrite existing image files III. Quali 1.Now live display of spectra on Sun-digital image, so can be easily exported Questions: --Objection to Quanti printout of low negative compositions as zero; if the value is negative, it should say that - makes students think, and if you want to average such values, you can't --Printouts should have the date and time of the last analysis, to help billing, etc --Print out should show background counts individually for both sides, not just the average. Also should print out the counting time. Claude Conty: they intend to add other matrix correction schemes as options Pierre Staub:he presented a short tutorial on detection limits (he will provide ref) which is somewhat different (better?) than the traditional calculation - will be on the new printout -- new features: if you miss analyzing an element, you can just analyze that element and add it to an existing analysis (without redoing all the other elements) --can recompute analysis using a different standard from a file --will include Merlet's thin layer program Questions: --Many users have found problems with the "Geologic" option in Quantiview. Cameca should either fix it or get rid of it. Is there a list of known bugs in Geo? (mentioned was the fictious Fe created in wollastonite) --Cameca needs to improve significantly instruction manuals it supplies. Suggestion: put them on a web page so that improvements, additions, updates can be implemented by Cameca rapidly and with the info getting easily and quickly to the users. --Cameca needs to fix its integration routine for Quanti: get rid of bogus warning messages; need to know how the background is calculated, or have options. Sam Pindrys (Service) --Cameca has hired 2 new enginers for sx service (Edgar Chavez, based in Phoenix; another undergoing training) giving them 6? now; they will be hiring two more. --If you call Sam, don't leave message on voice mail if you want to talk with him ASAP; dial "0" to get Bill Dempster or someone else who will locate Sam; also Cameca will send a reply to all messages they receive from users, even just to acknowledge receipt. --Service contracts: there had been 3 levels previously, now 2 (the lowest level was't really working out); First is "Contract" with full service (up to stated limits) with PM visit and free software ($23.7k); second is "Agreement" - 5 days of service and stated parts limits ($12.1k). Questions: --Is there a first and second class status assigned, so that those with the cheaper plan don't get immediate service? Answer: no, engineers will be assigned as jobs come in. --What if I have an "Agreement" and don't need to use it one year. Can I roll it over? Answer: No. "Use it or lose it." --The "Agreement" covers 5 days. If 1day (half Monday, half Friday) is spent traveling, then only 4 days are spent on service. Any consideration of that? Answer: We will think about it. Andy Davis: Cameca has just created a web page, bare bones to start with. URL is http://www.msa.microscopy.com/Cameca/CamecaHomePage.html Margie Mott (PGT): --the new SXN50 release will have the PGT EDS etc software integrated to run under Solaris 1.But porting the PGT software over to Solaris 2 will take longer, with estimated date of completion June 1997. Question: how come when I pull right on the PGT button on the root menu, I get a ton of features which my machine doesn't have? Answer: they can be removed from the menu if you like. At this time, the meeting adjourned for Cameca Hospitality Suite proceedings. [prepared by John Fournelle.

Last year at the users meeting in Berkeley, we talked about having some kind of manual on PM that might help us avoid expensive catastrophies ( e.g., regular cleaning of the diodes on your BSE detector). Dan Jacobsen said he would look into it, but I haven't heard anything more about it. One solution would be to see if Cameca would send Sam - or another well experienced engineer - to give our group a presentation on this. Personally, since I now have the XMAS software running on a decidedly older SX (#56), I am mainly interested in finding out more about ways to keep my aging probe running with a minimum of downtime and expensive repairs. We have experienced a marked increase in electrical component failures, electronic noise, and vacuum leaks in the past year or two. Thanks for all your efforts on behalf of the SX users' group.

The only thing I turn off when I leave (even on vacation) is the lights to the room. OK..., so I put the filament at 150. But that's it, unless it's a scheduled shutdown for a power outage. This way all the instrument protections are enabled and on-line. I mean what would one save? A few Kw-hrs?

We have replaced both pumps in the past year or so, again with Alcatel 2012A.

X-Listprocessor-Version: 6.0b -- ListProcessor by Anastasios Kotsikonas Another thing to think about : As a former vacuum technician I never really liked the direct drive pumps. Reminds me of an Italian sports car that really runs well but needs a full time mechanic. While the old fashioned welch pumps run slow and run forever, like an old model T. The direct drive pumps go through shaft seals constantly here. That's why when I bought our SX-50 I specifically got large welch pumps (rebuilt). They just tick away (I had two on my old probe that ran for 15 years without a hitch, except for one belt replacement). And they are cheap to rebuild. The pumps on my SX-50 are Welch 1397's available from Dunniway Stockroom in Mountian View, Ca for about $2000 each. (415) area code. The Cameca service guys were a little surprised but then commented how fast they pump the system down. john ==================================================================== =========== John J.

It is very useful. I plan to be at this years GSA and next years MSA meetings. I would stay an extra day after or before a MAS meeting for a longer SX meeting. Another alternative would be to have it in the evening again, but have the reception on another night. ie 7-10 pm, have dinner before. I have a request.

Particularly coming off the recent Minneapolis meeting, there appears to be a growing sentiment for well organized users meeting of several hours duration, (more than can be adequately squeezed into an evening during some conference), with several aspects: -- tutorials on various aspects of the equipment/software -- discussion of analytical techniques for 'tricky' samples -- discussion of hardware/software improvements/modifications -- discussion with Cameca regarding common concerns -- other stuff related to empa and our jobs/research It would seem that the best way to go about organizing such meetings would be to set aside a day prior to or immediately following one of the regularly scheduled meetings that many of us attend (MAS, AGU, GSA) and hold meeting of 4 or more hours to permit the above the above discussions. Certainly the optimal setting would be in a lab with an SX50 (or as we go on, SX100), realizing MAS/MSA meetings where Cameca has an instrument present on the floor present valuable opportunities for such user meetings. It would seem appropriate to begin discussion amongst ourselves about venues. FYI here are the upcoming meetings MAS (August) 1997 - Cleveland 1998 Atlanta 1999 Portland AGU (December) all Fall meetings in San Francisco GSA (October) 1996 Denver 1997 Salt Lake City 1998 Toronto 1999 Denver There also is the need/sentiment for having meetings that are multi-disciplinary, which the MAS meetings certainly are; on the other hand, there are many geologists who tend to attend the AGU or GSA meeting. Do we want to shoot for 2 full users meetings per year (MAS plus AGU or GSA)? Is there enough interest to do that? What do you think? I would think we should be flexible regarding the location: certainly San Francisco is attractive with SX50/51s at Berkeley and Davis; some of the GSA sites also have SX50s (SLC and Toronto). So the venues are optimal. Please give your opinion and suggestions. Specifically, 1) would YOU spend an extra day at one of the national conferences in order to hold a longer SX-users meeting with a technical session? 2) Which one/ones of the upcoming conferences in 1996 and 1997, do you plan to attend? Would you spend an extra day at this meeting for an sx-users meeting? 3) Do you have any specific topics you would like see discussed?

I hate to take notes, so it did not even cross my mind I should have. This has reminded me of an earlier suggestion that some tangible reward (enticement?) could be given to the individual(s) who would organize and systematize the email exchanges between SX users. I think that would be quite appropriate and fair. A trip to Paris was suggested, but I cannot go along with that because it might induce me to start taking notes, or do something even more demanding. Instead I propose to invite John to dinner, the next time we meet. Concerning our group, these are two things I learned in Minneapolis: Cameca will not respond to the requests for advice/help that we SX users exchange. To do otherwise would not be practical for them, and I have come to appreciate some of the difficulties involved. If we want their help we must ask them directly . Cameca would also prefer it if we organized ourselves in a more formal way, like, for example, Cameca ion probe users have done, in North America and, I think, in Europe. I do not have details, but the one thing mentioned to me is that they have regular meetings, and John Fournelle's suggestion ("Planning for future SX-user meetings") seems to move in the right direction. This should make it easier for Cameca to deal with our needs and requests. I am now reconciled with Cameca's silence while it reads about our difficulties, and I am encouraged by the signs I have seen of Cameca's efforts to improve communication with and response to us. I was particularly pleased by the hiring of Pierre Staub who seems to have moved quickly to address a number of quite old software bugs. It also has become clearer to me that we can and should make better use of our collective knowledge, for the very reason that Cameca will not reply to each and all of the requests we commit to email. This, of course, is not a new idea and in fact I know I have, somewhere, messages by Bruce Robinson and John Donovan (and probably others) making suggestions on hows and whats on the matter. One thought that occurred to me is that we could define general topics relevant to SX maintenance, repair and operation (i.e., what I mostly worry about) and that we could all contribute what we know on the various subjects. The information could be gathered and organized by one or more individuals per each general topic (the ones who take good notes, of course) so as to make the task less daunting. For example, 'spectrometers', 'stage', 'BSE detector' could be general topics, with subtopics like 'basic theory' (where applicable), 'common problems and fixes', etc. This does not have to happen overnight, in fact I expect it would take some time, since we all are quite busy and most of us are not good at taking notes, anyways. And why should these suggestions stir us into action, while the previous ones did not? For the simple reason that I am ready to receive and organize your comments and suggestions, as a first step towards the ultimate goal. One step at a time. As for myself, I shall start by retrieving Bruce's and John's letters. From ???@???

The other concern I have is if we can logon to control the SX with a terminal emulation program into the SXlocal window for instrument control. I do find this very useful when either my Sparc/Sun is down or being used for non-probe activities. So, with the "new" software, which does not use the sxlocal window, will we still be able to use out IBM with terminal emulation for SX control? From ???@???

As for myself, I shall start by >retrieving Bruce's and John's letters. I agree, this would be useful if organized on a searchable web basis. Perhaps it would make things easier if the subject line was used to organize email letters that contained useful information. However, I know that I don't always provide informative enough subject lines. I have for a number of months simply printed out e-mails from those in the users list that I thought contained information that might someday be useful to me. The problem is that it's all in one file folder and rapidly getting too large to thumb through.

Tom was instrumental in helping to start this users's group and actively participated in it. On Friday of last week, Tom was driving his motorcycle to work when he was hit by a truck. He was killed on impact. All of us in geology at the Univ. of Hawaii and many at U. Mass who got to know him over the last few months are deeply saddened. He was friend to all who knew him. Any of you who would like more information are welcome to contact me. Mike Garcia University of Hawaii (Temporarily in Australia) From ???@???

I will probably be attending GSA in Denver and SLC. I would be interested in having a one day workshop on the SX50. Any of the issues and subject matter suggested in previous notes on this list would be of interest. Thanks for your summary of the SX50 meeting at MAS this summer.
