Greetings Raith Community:

I have been watching the Raiths emission and gun section vacuum levels 
carefully over the course of the last month.  The FE-Gun has been  nice 
and stable for the past ten days and I ran the gun up and wrote at 25 kV 
in a test this week.  Vacuum continues to hover in the 1.5 - 2.6E-009 
mbar range.

 Users are now cleared for all operations to 25 kV acceleration 
voltages. Please be sure to please pre-bake all samples going into the 
system on the 90 degree hot plate. Next steps will be 30 kV testing will 
be performed  late next week.


Thank you for your support!

James Conway
