Without it we are not able to load samples into the SEM properly. Please bring if back !!!!!!!!!!!!!!!! and thank you very much for delaying our work.

While I don't know enough about the 4160 to know where this is used or to know which is the proper size, I've left 3 sets of allen wrenches that, I think should allow you to proceed: 1. I've left my metric set that goes down to 1.5 mm (in the red holder) 2. I've left a metric set in the blue case that has even smaller metric sizes (0.7, 0.9, and 1.3 mm) 3. Finally, although I doubt that the Hitachi uses english sizes, I've also left a set of english allen wrenches that goes down to 1/16" and 0.050". That's the set in the yellow holder. Note: none of these are guaranteed to be particularly clean so you probably want to wipe the proper one with a lab wipe and some isopropyl before using it on anything that will be inside the vacuum chamber. Hopefully, one of these will get you back on the air ... and, if you tell me which one is the correct size, I'll get several to be placed in the tweezer box.

The 0.9 mm allen key from one of your sets you left at the SEM fits. I put this one from you allen key set in the tweezer box and I left the the other sets at the SEM. We already used it for one SEM session this morning and will again later in the evening today. Thanks again for providing one so fast, John !

Message-ID: <489CBB01.7040507@snf.stanford.edu> Hi Debbie, If you are free I am going to be working on the S4160 after ~3:30 PM today. I would like to review with you the column set up and make sure you obtain the brightness you need to obtain your image or measurements. Likely you came onto the system when it was set up for imaging very tiny structures using the smallest apertures and encountered less beam current than you are accustomed to. If you are not here or available this afternoon please stop by Monday afternoon when I will likely also be working on the tool with the Hitachi Field service experts whom are here doing repairs to EBEAM.

Possibly mechanical alignment is necessary to eliminate what could be consider tilt in the axial alignment of the gun to the column axis. jwc at snf.stanford.edu wrote: -------------- next part -------------- An HTML attachment was scrubbed...
