Good Morning,
Yesterday we tested for the second time an entire afternoon of write operations at 30 kV with no problems.  Gun pressure base level is 5.2 E -010 Torr and system presuure base is 1.9 E - 006 Torr.  Very stable gun emission and nominal beam currents levels have been observed.  
Users can now utilize any ACCELERATION Voltage from 0.3 to 30 KV.
ALL SAMPLES GOING INTO THE SYSTEM MUST BE SOFT BAKED JUST BEFORE LOADING INTO RAITH.
Thank you for your support,
James Conway
