From charley at snf.stanford.edu Mon Apr 12 10:48:44 2004 From: charley at snf.stanford.edu (Charley) Date: Mon, 12 Apr 2004 10:48:44 -0700 Subject: New item! Message-ID: <407AD67C.3020002@snf.stanford.edu> The specimen holder in the 4160 has been held by sticky dots. This may have led to some drift in the image if the stage was tilted. To cure that, I put a screw into the hole for that purpose, and put a little hex wrench in the box. It has a soft black "handle". DO NOT LOSE THE WRENCH. DO NOT USE ANYTHING ELSE TO TIGHTEN THE HOLDER. This wrench, with the soft handle will not allow overtightening of the screw. The screw should be tight enough if you just tighten it by hand-NO FORCE is needed, here! chw3 From charley at snf.stanford.edu Tue Apr 20 10:36:05 2004 From: charley at snf.stanford.edu (Charley) Date: Tue, 20 Apr 2004 10:36:05 -0700 Subject: Again... Message-ID: <40855F85.7000402@snf.stanford.edu> Last night, the last user left the machine in fast scan, low magnification. Great! That means you are working the deflection system as hard as you can, all night long! This is not acceptable. Pay attention to what you are doing, here. If you wreck the machine, IT WONT WORK WHEN YOU NEED IT. chw3 From mtang at snf.stanford.edu Tue Apr 27 08:55:39 2004 From: mtang at snf.stanford.edu (Mary Tang) Date: Tue, 27 Apr 2004 08:55:39 -0700 Subject: SEM Use -- and Abuse Message-ID: <408E827B.D1EF4817@snf.stanford.edu> Attention all SEM users: It has been brought to my attention that there are issues with the SEM's, many of them appearing to be user-induced (machines not left with stand-by settings, apertures and other non-user adjustments made, loader rod screws stripped, web-surfing-induced Semicaps errors.) Remember, these machines are shared but it's each individual's responsibility to do his or her part to keep them in good order. If necessary, we will revisit the guidelines for qualification and rules for how to keep qualifications. This is a reminder to do (as you should always) the following: 1. Make sure the machine settings are in standby condition, both before you start using it and after you are done. Charley has posted signs and provided operating procedures which should list the appropriate settings. 2. Don't touch settings that are not user-adjustable. 3. Nothing on these machines should require force to use or operate. If it does, then report it so that it can be repaired before being permanently damaged. 4. Clean up after yourself (gloves, samples, wipes, etc.) 5. Report ANY problem you may observe to Charley AND on Coral. 6. If you have any questions or are unsure about operation, contact Charley. Please realize that all these are very important, but that points #1 and #5 may be especially important to SEM users... When there's a problem (for example, the loader rod screw this weekend), lacking any more information, we will attribute the problem to the last person enabled on the system and may enact disciplinary measures which may include dis-qualification. A final note: Problems happen and mistakes are made. As experimentalists, we always want to try something new, and many times it doesn't work, sometimes with disastrous consequences (let me tell you about when I had to tell Len that I blew out the diffusion pump oil on the MRC, just an hour after he told me how to avoid doing this). But we are an educational organization, and therefore expect this. However, we also expect that labmembers should accept responsibility for their actions and be willing to help us address any issues which may result. Remember, when there's a problem with the machine and if you do NOT report it, the next person could waste hours trying to get it to work and staff members could spend hours trying to diagnose it. You save everyone time and energy by reporting the problem in detail as soon as you note it, thereby notifying other users so they don't waste their time, and staff members who can address it as soon as possible. By the way, the list of things-to-do above (aside from references to Charley) are applicable to any tool in the lab, (as is the expectation that each person takes responsibility for his/her own actions.) As always, if you have any concerns or issues about this area (or the lab in general) please come to Charley, me, or any other staff member. OK, I'm coming off the soapbox.

I have another pump for the oven, and I'm checking it out now, but if it doesn't work, I'll need the pump. Coat what you need to coat soon. It may be a day or so before I get the pump back on the Hummer..... chw3
