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

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.

 

 

  1162   Friday, March 04, 2016, 12:34 David WangITEStandard OperationTM4 TM4 ITE annual leak check

Dan and I finished TM4 and ITE annual leak check on primary and secondary vacuum vessel. We found one leak on a KF25  blank off which is located on the top of the service cap. It is a low E-7 atm.cc/sec range leak. But, it is very close to turbo-pumps so ITE IG1 and other gauges are not affected by it very much. It is an easy fix. TheKF -25 center ring on the blank off  will be replaced  after vent . It be will leak checked again at CS after replacement.  That is only leak we found on TM4 and ITE primary and secondary vessel air to vaccum leak check.

Dan and I also finished the helium pressure test on all TM4 using water circuits. 70 psi helium. base LR 0.0xE-9 atm.cc/sec. All of them are leak free. No any response has been found on leak detector during test.
