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.
