Container was sprayed with TaC and let dry.

Container has 3x Ta heat shields including center block.

Container was loaded into EVAP2 yesterday and pumped down overnight.

HS water valves were opened up this morning, no leaks detected.

IGP1 = 4.6e-7 Torr.

Tapped up manually to 40A.

Waited ~25min, Vacuum stable.

IGP1 = 5.0e-7 Torr.

Initiating auto-ramp.

TGHT will be ramped to reach 2000C

IGP1 = 4.5e-7 Torr.

TGHT = 313A, 4.47V

OMEGA = 1444C

Increasing ramping rate to 1.0A/min


 Friday, June 05, 2015, 11:31

IGP1 = 1.2e-6 Torr.

Increasing ramping rate to 2.0A/min

TGHT reached to 465A/7.56V, temp is stable at 2000C. Current vac at 1.2e-6 Torr and coming down

Cooling down process can be initiated after 4 hours.
