  1158   Thursday, February 25, 2016, 09:27 David WangITWStandard OperationTM2 TM2 has been disconnected in ITW

TM2 has been disconnected in ITW (except vacuum lines). The vacuum system is still operating.

  1160   Wednesday, March 02, 2016, 09:51 David WangITWStandard OperationTM2 all water lines on TM2 and TM4 are purged.

All water lines on TM2 and TM4 are purged for upcoming water lines helium pressure test.

  1161   Wednesday, March 02, 2016, 10:04 David WangITWStandard OperationTM2 Leak check on ITW and TM2.

Dan and I leak checked TM2 and ITW primary vacuum vessel. It was found a 1X E-7 atm.cc/sec leak on top T flange seal between TM2 and dump module in first time check. But it is not a repeatable leak. I checked the same spot and around area two more times with increased helium volume.It did not show up again. The first response could  be a helium drift to dry scroll pump. I will check it again later. The primar vacuum vessel on ITW and TM2 are leak free. 

Dan and I found a small  leak on ITW dump module  top flange seal. The leak detector got a response  to 7xE-9 atm.cc/sec when I spray the helium to west side of dump module top flange. We tested again, and got same result. The o-ring which seals ITW dump module top flange is deteriorating. It need to be replaced at a proper time. This is the only air to vacuum leak we confirm so far on primary and secondary vacuum vessel on TM2 and ITW. The module and station no other air to vacuum leak.

The TM2 water lines helium pressure tested started in ITW. The helium pressure 70psi. The result so far is: Window: good, GE: huge leak directly shoot over E-7 atm.cc/sec( need to be confirmed tomorrow), HS: good, EE: good, MSP: tiny leak which is response to 3-4xE-9 atm.cc/sec. Coil 1 : small leak which is response to 1.3XE-8 atm.cc/sec. Tomorrow, We will test the rest water lines on TM2which are TA+, TA-, Tube+, Tube-, and coil 2. And We will confirm the GE huge leak at the last.

Finished the helium pressure test on TM2 water line.70 psi helium, The result of the rests 5 circuits: coil 1: leak 7.2xE-8atm.cc/sec,Ta(+): small leak 1.7XE-8 atm.cc/sec, Ta(-) small leak 8.7xE-9atm.cc/sec,Tube(-) 1.5 x E-8 atm.cc/sec. Tube(+)small leak 3.7xE-8 atm.cc/sec.    We repeated the helium pressure test on GE. There is a huge leak on TM2 GE circuit. The leak detector shoot up to E-7  atm.cc/sec right after the helium was applied.It went up to E-6 range in less than 1 minutes.

 

 

  1191   Tuesday, April 05, 2016, 09:33 Travis CaveITWStandard OperationTM1UC#15module moved

TM#1 with UC#15 have been moved from the conditioning station to the west target station.

  1192   Tuesday, April 05, 2016, 12:36 David WangITWStandard OperationTM1 TM1 vacuum system has been connected in ITW.

 All turbo -pumps are started.

  1199   Friday, April 08, 2016, 07:13 David WangITWStandard OperationTM1UCx15TM1 has been connected in ITW.

After ITW HV test is done, TM1 has been connected to ITW. Water signals are checked in electrical room. They are good.

  1201   Friday, April 08, 2016, 08:48 David WangITWStandard Operation  ITW water signal interlock check.

I did a ITW water signals interlock check with ISAC opp. They are checked once a year before first beam on.

2016-04-13 Same test is done on ITE also. Everything is good.

  1212   Thursday, April 14, 2016, 12:56 David WangITWStandard OperationTM1 5 shielding blocks have been moved to ITW.

The ITW is configured to take proton beam.

  1234   Monday, May 16, 2016, 11:16 David WangITWStandard OperationTM1 ITW, TM1 turbo-pumps are swithched 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.
