Target container is coated with TaC.

Container is wrapped with 3x Ta-heat shields.

Currently being pumped down.

For sintering process:

TGHT and TBHT will be ramped up to 820A and 300A respectively at 0.1A/min

HS water cooling valves opened, no leaks detected.

IGP1 @1.8e-6 Torr

TGHT max = 820A/ 17V

TBHT max = 300A/ 5V

Stepped up manually to 40A, waited ~20min, vacuum stable.

Initiating auto-ramp @ 1.0A/min


 Wednesday, June 18, 2014, 11:24

TGHT and TBHT reached their respective 820A and 300A last night.

Internal temp measured from side of EVAP2 with mikron = 1830C

IGP1 = 7.6e-7 Torr

Initiating auto-cool down process at 2.0A/min and 1.0A/min for TGHT and TBHT respectively


vented and opened this morning.

smooth run
