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
Thursday, January 30, 2020, 09:32
Current ramp set to 1A/20s to 150 A (same pressure limits)
Pressure keep increasing during heating
Thursday, January 30, 2020, 09:53
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.

Pressure decreasing:
TGHT= 153 A
