NiO target materials loaded into the container yesterday.

Total discs = 530, (5 discs/pack)

length [after loaded] = 9.0cm

Target container is wrapped with Ta-heat shields, and will be removed after sintering process.

No end caps were inserted.

The chamber has been pumped down and currently IG1 = 3.8x10-06 Torr.

The HS cooling water was turned on and no leaks were detected.

TGHT and TBHT have been stepped up to 50A.

Auto-ramping setting:

0.2A/min for TGHT max = 250A, TBHT max = 230A.

Good vacuum = 3.00e-05 Torr

Bad vacuum = 4.00e-05 Torr

Pressure is stabilizing at ~2.2e-5 Torr.  TGHT/TBHT at 50A.

Initiated auto-ramping...

TGHT/TBHT have reached to 250A/230A.  Target have been heated over the weekend.  

Cooling down initiated; 2A/min.  

The chamber wil be vented in air tomorrow.

The sinterring process is complete. 

The target is ready to be removed from the evaporator, and the endcaps will be inserted.
