TM2 and TCS vacuum system has been connected. I started all turbo pumps. Everything is good so far.

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.

 Filled from 15 to 25 in

 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

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

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.

Thursday, June 09, 2016, 10:44: Started heater ramp. TGHT / TBHT to 40 / 20 A at 1 / 0.5 A/min. IG2 vacuum limits 2E-6 / 3E-6 T

Thursday, June 09, 2016, 11:59: Continue ramping to 100 / 50 A.

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.
