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 ???@???
