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
at RAITH USA.
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
Thank you for your support! Please play nicely together,

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!
