  1226   Tuesday, May 10, 2016, 13:54 David WangSouth Hot-CellStandard OperationTM2 SHC, TM2 leak check on window line and HS line.

Chad and I leak checked the TM2 HS and window lines after new target installation.  The window line was very easy pumped down on LD. But, The HS line only could pumped to 2-3 torr at first. Chad changed the VCR gaskets on HS line(target). It solved the problem. The LD could pumped  both of Window and HS lines to the bottom scale. Chad sprayed lots helium around the VCR joints.  No leak has been found. WE will do helium pressurizing test on them at TCS.

These two lines are passed helium pressure test this morning. The LD base leak rate 0.0 X E-9 atm.cc/sec. The base pressure 0.0 X E-4 torr. Helium pressure 70 psi. applied helium to both line for 5minutes each. No response on LD during the test.

The HV  cover is installed on to TM2 after the connections. The HV key is returned back to B2 level. The TCS Faraday cage is locked.

Monday, May 16, 2016, 15:45: Paused ramping.

Monday, May 16, 2016, 15:00: Resumed ramping

Monday, May 16, 2016, 16:23: Stopped ramping for the day. TGHT / TBHT at 310 / 220 A. FC at 6.2E-7 A


Tuesday, May 17, 2016, 08:00: Continue ramping.


Wednesday, May 18, 2016, 09:40: BIAS / EL / EE to 35 / 17.5 1.7 kV


Thursday, May 19, 2016, 04:07: BIAS dropped to 0. Likely caused by a power bump.

Thursday, May 19, 2016, 08:05: BIAS returned to 35 kV. Increased EL to 22 kV to maximize FC current.

Thursday, May 19, 2016, 08:11: TBHT to 230 A

Thursday, May 19, 2016, 08:22: Ramping down TGHT / TBHT

Thursday, May 19, 2016, 10:41: BIAS / EL / EE off

LD base LR: 0.0 X E-9. Base pressure:0.0 X E-4. 70 psi helium. 5 minutes each circuit.

window 0.0X E-9  
HS 0.0X E-9  
EE 0.0X E-9

MSP 3.5X E-9  

The bigger leak found on MSP before was gone. Leak rate are smaller on all circuits  comparing to before. 

The leak rate on 1 hour total lines test at 70 psi is better also which is 6.6 XE-8 atm.cc/sec this time.
