Total number of foils: 422 discs

Total mass of materials [incl graphite foils]: 

Total length packed: 12.0cm

Container has one Ta heat shield.

No endcaps inserted to allow outgassing

Two TaC coated Ta wires formed into a spring inserted either end to avoid ZrC expansion of materials.

Currently being pumped down.

HS water valves opened.

No leaks detected.

Initiating ramp up.

EVAP2 was tapped up manually to 50A.

Vacuum tripped evap off.

Tapping back up manually now...

Tapped up manually to 45A for both TGHT and TBHT

IGP1 = 4.8e-5 Torr

Will initiate auto-ramp at 0.2A/min and 0.1A/min for the TGHT and TBHT respectively once vacuum settled down and stable.

Max setpoints set to 520A and 230A for the TGHT and TBHT respectively.

Good Vacuum = 3.0e-5 Torr. Bad Vacuum = 4.0e-5 Torr.
