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

The TCS and TM2 are still under vacuum without venting

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. 

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

TM#1 has been moved from the south hot cell to the north west silo.

TM#1 with  UC#15 has been moved from the west target station to the south hot cell. The target shield plug was also remotely installed as well.

TM#1 with UC#15 was moved back to the west station due to alpha concerns.

TM#1 has been moved from the west target to the south hot cell. The target on TM#1 is UC#15.

 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.

I let isac opp switched off ITW turbo-pumps. The argon vent valve in electrical room is opened. The ITW argon venting will be started  soon.

 Filled from 15 to 25 in

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.

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.

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

I changed TCS tank top flange seal(o-ring 42.00"ID X 0.275" DIA) this morning before TM2 was moved to TCS.

TM#2 with Ta#48 has been moved from the south hot cell to the conditioning station.

Electrical check of TM#2 with Ta#48 attached. See the attached PDF for details.

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.

Ta#48 has been installed onto TM2. Also new window gaskets were installed.

High current fasteners were torqued to 130 in lbs. Shutter side of the containment box recieved new fasteners.

TM#3 was moved from the conditioning station to the NE Silo. TM#2 was moved from the SW Silo to the South hot cell.
