The coated container was wrapped in 4 Ta foil heatshields.
Target temperature on OMEGA= 1850-1900 C
OMEGA slope:= 0.990
Target time at max temperature = 4 hours
Final Current TBHT= 230 A
Final TGHT current= ~400A (adjustable)
Heating autoramp starged at 2A/min(1A/30s) on TGHT 100A
Then at 4A/min to =400 A TGHT and 230A TBHT
Good vacuum = 5.0 e-04 Torr
Bad vacuum = 5.0E-02 Torr
Initial IGP1= 8.7e-07 Torr
Saturday, August 26, 2023, 10:54
IGP1= 1.2e-06 Torr
Start ramp up at 4A/min on both heaters (2A/30s) until TGHT = 400A and TBHT=230A

Paused ramp to allow temperature to stabilize and record data
OMEGA= 1396 C
IGP1= 2.47e-06 Torr
Saturday, August 26, 2023, 11:52
Paused ramp to record data
OMEGA = 1544 C
IGP1=3.4e-06 Torr
Saturday, August 26, 2023, 12:09
Paused ramp to record data
OMEGA = 1653
IGP1 = 4.5e-06 Torr

Omega went up to 1878C. Lowered the current on TGHT to reach OMEGA = 1857 C
Will keep until 430 pm
