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

Thursday, May 19, 2016, 14:00: TGHT / TBHT off

Friday, May 20, 2016, 14:39: RGA off.

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.

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. 

The TCS and TM2 are still under vacuum without venting

Weekly update the TH schedules. See attachments 1, 2,3.

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

Bill and Yasmine did the move remotely this afternoon. The move is successful.

TM4 and TCS vacuum system are connected.   Turbo pumps are started.  Everything is fine so far.

Monday, June 13, 2016, 18:02: Ramping down TGHT / TBHT at 2 / 1 A/min

Monday, June 13, 2016, 21:39: Source off. Water, RGA, vacuum off.

I did a helium pressure test on TM4 at TCS with UCX16 target installed on the module. No leak has been found on all using water lines in TM4. See attachment for detail.

It is ready for HV conditioning/ heating. 

Weekly update .

The TM4 and TCS are vented with argon. 

I switched off the vacuum pumps and vented TCS with argon. The TCS will be ready to accept TM2 this afternoon.

TM#2 with SiC#33 has been moved from the south hot cell to the conditioning station.

The TCS and TM2 are pumping down.

 Wednesday, July 06, 2016, 15:23: RGA on. IGs on

Friday, July 08, 2016, 17:07: Stopped cooling system due to a problem with the chiller. Will continue with HV conditioning on Monday.

Monday, July 11, 2016, 08:08: Cooling system started. Operating CP1 manually to control temperature

Monday, July 11, 2016, 12:21: BIAS / EL / EE off to investigate TGHT / TBHT PS problem (power surge this morning)

Monday, July 11, 2016, 13:07: Power cycled TGHT / TBHT PS. Alarm cleared. Tested both to 10 A

I connected TM2 to TCS and started water system.

Plant Services group (Tony) will contact a service tech on Monday.

Water system will be switched off over the weekend.
