It is my pleasure to announce that the system is back online in normal 
functionality.  Today's qualification run is well within specifications 
with  stitching below spec and superb overlay registration.  The chip is 
in my dry box if you wish to inspect it. 06192003_6.chip  QUAL8282004 
red sticker on wafer box.  3.3 U 6.2 V position

RESTRICTION: NO operations above 10 keV  DO NOT operate above 10 keV.  
See below ...

Should there be any problems or EHT trips immediately inform cole loomis 
Zeiss should return later this week to check adjustments made on the 
system after the system has had several more day to run in.

I will be unavailable and will be away from the Lab returning September 
13, 2004

Thank you for your support! Please play nicely together,

James Conway

we wish to allow the FE-gun two weeks of conditioning before we resume regular operations.  This is to allow the FE-tip to condition itself and run in properly.
System was tested repeatedly to 30 keV with no EHT trips or vacuum out gassing above normal levels.  This is just a precaution to ensure a long bright FE-Gun tip life.
Thank you for your support!
