container has 4 Ta heat shields

one endcap at front

max approx 380A on TGHT

Then temperature = 1850C

Slope will use is 0.980 

Good vac at 5.00 e -4 Torr

Bad vac at 5.00 e-2 Torr

Start ramping at 2A/min 

IGP1 initial = 8e-06 Torr (small amount of discs so can ramp up fast)

OMEGA read 1600 C.  Left for 4.5 hours.

final TGHT current = 382.5 A on readback and 390 A on setpoint

final TGHT voltage = 6.9 V

Adjusted temperature so as to not overheat small amount of discs in cartridge.

Ramping down at -2A/min
