A P2N container  with heat shields, and with a UO2/C loaded graphite container was installed in the EVAP1

Chamber is currently being evacuated.

Pressure limits:

Good vacuum 1e-1 Torr

Bad vacuum 5e-1 Torr

Initial pressure: 

IGP1=1.52e-6Torr

Current ramp set to 1A/min to 10 A, voltage is stable.

Current ramp increased to 1A/10s to 100 A. The pressure started raising around 80 A.

Current was kept 5min at at 100 A, voltage was stable

Current ramp set to 1A/20s to 150 A (same pressure limits)

Pressure keep increasing during heating

Current was kept at 150 min during 5 min, the voltage is stable, pressure started to stabilize:

IGP1 = 0.027 Torr

TGHT = 0.418 V

Ramp set to 1A/min to 200 A.
