Cartridge-220510Cx was installed in the EVAP1 and pumped down yesterday.

Material will be further conditioned at 450A for 4 hours.

The material will be conditioned inside a container tube with both ends open at the ends.  Two springs are inserted at the ends of the graphite cartridge to contain the material as graphite caps not inserted.

IGP1 = 7.8e-07 Torr

Good vacuum = 5e-4 Torr

Bad vacuum = 5e-2 Torr

Will autoramp @2A/30s (4A/min) to 40 A and then to 120A.  Fast ramp rate because material had previously been conditioned
