Pressure lowered after passing outgas peak.
IGP1= 2.5e-05 Torr
will continue with step 2 of ramping
Thursday, September 12, 2024, 14:46
At 115A outgas peak observed and current ramped down from 120A t 115A. Allowing pressure to drop before continuing ramp.
Roughing pump issue. Cooling, turning pumps off until vacuum group can take a look.

Roughing pump seems ok. Restarting ramp at 1A/min to 115A
Friday, September 13, 2024, 17:38
Starting ramp up at 2A/min to 520A (will monitor pump and outgassing)
Saturday, September 14, 2024, 07:44
inflection point at aroung 450A
Saturday, September 14, 2024, 07:48
pressure started dropping at 466A, but some sporadic peaks observed. Will heat to 488A and leave for 4 hours
Saturday, September 14, 2024, 20:23
ramping down after 8 hour conditioning
IGP1= 2.45e-06 Torr
