The target container was previously coated with TaC and sintered in Evap 2.

The target is loaded with 250 discs of UCx (material from batch#09_06022014)

Total length = 9.3cm

The container is wrapped with 3 layers of Ta-heat shield, including the back block.

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

(Did not use a D-cap... This worked for UCx#8. Need to be careful when handling the target!)

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.
