Good Morning,

Yesterday we tested the system to 20 kV acceleration voltage during 
Peter Catrysee's EBL write. I briefly ran the gun up to 26 kV and 
observed no elevation in the vacuum levels or EHT trips.  I will be on 
the system this afternoon and evening and hope to complete more 
operations at higher acceleration voltages to confirm our FE-Tip has 
been properly conditioned.
More PCM qualifications and measurements in the queue...

Questions -- please visit me during my office hour.

Thank you for your support!

James Conway
