We have tested the FE Gun operating at 20 kV, and again today at 30 kV 
acceleration voltage.
We observed no problems with Gun Vacuum or EHT trip events during these 

Users are now allowed to select any acceleration voltage between 0.3 and 
30 keV for their EBL writes.

The new High Efficiency In-Lens detector has also recently been ordered, 
and it is being built for us by LEO in Oberkocken, DE.  It will be 
installed during the next service call by RAITH Field Service personnel.

Thank you for your support!
