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.

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.

Disconnected  TM2 at TCS(vacuum system still on). Purged all TM2 water lines for helium pressure test.

  1241   Friday, May 20, 2016, 10:38 David WangConditioning StationStandard OperationTM2Ta#48Helium pressure test on TM2 with new Lp Ta target

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  
Ta+ 0.0X E-9  
Ta- 0.0X E-9  
coil1 R-U 0.0X E-9  
Coil2 P-Q 5.0X E-9  
Tube- 5.1X E-9  
Tube+ 1.1X E-8  
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.

Chad and I finished the TM4 UCx6 electrical check and leak check at SHC. Leak check result on HS line is good. There is a dead short between "Z" repellor and HS during the first time electrical check. The dead short disappeared after re- installation of UCx 14 target onto TM4. See attachment

 Anders and I did another electrical check on TM4 at TCS under vacuum. See attachment 2
