Target container was previously coated and sintered with TaC.  It's wrapped with 3-layers of Ta heat shield, including the center block.

The target consists of 280 discs of UCx with 9cm in length.

A regular TaC coated/sintered endcap is inserted on right, wrt to the ionizer tube pointing down, so the left end is open with no cap to allow out-gassing.

The chamber is being dumping down.

TGHT will be ramped up to 520A - keep heating at that current for ~4 to 5 hours.

Parameter setup: 5.0e-5 good vac, 6.0e-5 bad vac. The auto-ramping rate is set to 0.1A/min.

Pressure at 1.9e-5 Torr. 

Initiate auto-ramping- stepping up from 0A at 0.1A/min - leaving for the weekend.

TGHT has reached 520A and target has been conditioned at that current for 13hrs. 

Auto-cooling initiated at 2A/min.

Once the target is cooled, the chamber will be vented in Ar.
