Greetings Raith Community:

All Users can now operate the RAITH system up to but not to exceed 20 keV acceleration voltage.
Yesterday I tested and operated the system at 20 keV
acceleration voltage with no problems. Gun section vacuum remains at the ~ 1.2 E -009 Torr.
I expect this pressure to slowly decline into the mid E -010 Torr level in the coming week.

More testing during late next week.

Thank you,

James Conway
