 Monday, May 16, 2016, 13:20: BIAS/EL/EE 30 / 15 / 1.5 kV

Monday, May 16, 2016, 13:20: Ramping TGHT / TBHT to 580 / 220 A at 2 A/min. IG2 1E-6 / 2E-6 T

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

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

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

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.

I did an electrical check on TM4 with the old target still installed. The number is a little bit low on 500V mega check between chassis and 60KVbias which is 146Mohm. Others are good.    See attachment

I wrote all OL to 0  in attachment 1 ohmmeter check. Please See attachment 2 for correction.
