Wednesday, January 14, 2015, 13:46: Roughing
Wednesday, January 14, 2015, 14:57: Starting turbo
Monday, January 19, 2015, 13
Water opened up to one circuit at at time. No response on the vacuum could be seen.
IGP1 at 1.7E-7 T
IGP2 at 3E-8 T
Tuesday, January 20, 2015, 13:11: Stopped turbo and roughing pump.
Wednesday, January 21, 2015, 15:46: Venting
Rick and Anders found CG1A to be reading too high a value. A borrowed gauge from the vacuum group confirmed this. A new gauge will be installed
Thursday, January 22, 2015, 14:06: Roughing
Thursday, January 22, 2015, 14:18: Venting
The reading is consistent between CG1A and CG1B, which simplifies pump down. |

After inspecting the target container, the inner tube surface has "dark" patches, which may not be evenly coated or the coating layer was too think.

Attempt to re-spray the container and re-sinter.

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.
