Target container is coated with TaC. No Ta-heat shields are used.

TGHT will be ramped up to 580A at 0.2A/min.

TBHT will be ramped up to 230A at 01A/min.

Chamber is currently being pumped down.

HS water valves were opened. no leaks detected.

Tapped up manually to 35A.

Once vacuum stabilized after ~45min, initiated auto-ramp.

IGP1 = 5.3e-7 Torr.

TGHT = 250A and TBHT = 140A.

Increasing auto ramp to 2.0A/min and 1.0A/min for the TGHT and TBHT respectively.

TGHT/TBHT are at 580A/230A for almost 6 hours, temp at 1728C.

Vac at 8.5e-7 Torr. 

Cooling down initiated at 1A/min.

Target container should be inspected once the chamber is vented.
