Total number of foils: 377 ( including 6 analysis discs on the right side of the container)

Total weight = 1454 g (includes heatshields, spring and T bar)

Total length packed 15.5 cm (excluding 6 analysis discs that will be removed)

container has 3 Ta heat shields and is coated

No endcaps inserted to facilitate out-gassing

Ta coated spring at  front (right) side

Initially to ramp TGHT and TBHT to 80A at 2 A/min

then to 120A and slow down ramp when pressure begins to increase

max approx 675A on TGHT and 230A on TBHT (Omega slope set = 0.990)

Then temperature = 1800C

TBHT will be set fixed at 230 A (max).  TBHT heated manually and automatically to max.

Good vac at 3.00 e -4 Torr

Bad vac at 5.00 e-2 Torr

 IGP1=3.6 e-07 Torr at start of initial ramp.

IGP1= 7.1 e-05 and dropping.  Start ramp to 150A for both TGHT and TBHT @1A/min

Tuesday, June 21, 2022, 21:27

Increased ramp rate to 3A/min for TGHT to 675A

Tuesday, June 21, 2022, 22:38

Ramp up to 685 A on TGHT and leave for 4 hours. 

OMEGA = 1645 C but suspect reading not on Ta surface.

Wednesday, June 22, 2022, 02:28

IGP1=7.7e-6 Torr

OMEGA =1610C

TGHT = 685A, 10.5V

TBHT = 230A, 3V

initiate rampdown at -2A/min and -1Amin TGHT and TBHT
