Bruce:

I asked Jean-Michel about the communications between engineers and it
sounds like it continues to be the informal approach.

Regarding associate editors, do you know (or of) the CAMUS group in
Germany etc? Apparently they meet every 18 months for ~3 days I think at
someone's lab, with talks,demos, presence by Cameca engineer/applications
person/s. I've tried making contact and have only 1 fax from one of the
leaders (?) of it. No mention of a newsletter. Might be good to see if
they want to get involved too.

I'd like to hear more about the user tasks that you mention folks
have written to shield novices from f*cking up the machine. Our setup
here calls for heavy use by students of various levels of training and
aptitute; the most recent foulup (too 1-2 weeks to figure it out) had to
do with users typing garbage into the "Standard Position" window by having
the cursor not in the intended window, and overwritting standard
compositions, etc -- the error messages were too crytic to figure out
the exact location of the problem... So I've been trying to figure out
how to "shield" the SX from such things.

Re the sub-micron stage, I still do not understand it all but think
they have gone back to stepping motors, but the details are not totally
clear (like I think they still use the optical encoders in some
combination?).

Yes, officially we have a SX50, with 2 SONY monitors (replacing the green
CRTs) with frame store and the new stage. Details like that don't filter
down to the sales/PR people (plus I suspect we were a guinea pig, in case
it was a flop they wouldn't have to eat too much crow).

Our HV tank is oil filled; J-M did not want to take it up to 50 KeV. 40
was the highest he took it to; I had an arc in the gun at mid 30 KeV
range...
