Friday, March 07, 2014, 12:45, David Wang, ITE, Standard Operation, TM3, , TM3 and ITE air to vacuum leak check and TM3 water lines helium test.
|
With TM3 located in ITE, All air to vacuum seals on ITE primary and secondary vacuum vessel have been leak checked with leak detector hooked
directly on the TM3 service cap.The base LR :00xE-9atm.cc/sec. The ITE IG1 was 1.6xE-6 torr which was good. No leak has been found during the checking.Also,
the TM3 water lines(except HS) had been pressurized with 70 psi helium on each for 2 minutes. There was no response during the test. The ITE and |

Thursday, March 06, 2014, 14:12, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 air to vacuum and water lines leak check at CS. 8x
|
TM1 air to vacuum and water lines leak check at CS are finished this afternoon. The leak detector is hooked directly to TM1 service cap so the
base LR at LD is 0.0xE-9 atm.cc/sec. I sprayed helium to all air to vacuum seal on the service cap, also applied 70 psi to all water lines(except HS) for
2 minutes each. There is no any tiny response had been found on LD. So All TM1 water lines(except HS) and air to vacuum seals are leak free. The HS circuit |

Thursday, March 06, 2014, 06:58, David Wang, ITE, Maintenance, TM3, , ITE vacuum and leak check on ITE BL2A window flange.
|
ITE and TM3 Turbo pumps have been started successfully yesterday. The vacuum reading on all ITE high vacuum gauges are at low E-6 range after one night
pumping down which are good so far. There is no any sign of leak on BL2A window and the flange seal on ITE side. Yesterday afternoon, Ron , Edi ,and I
did a leak check on the ITE BL2A window flange(2aTunnel side). The leak detector was hooked onto BL2A in tunnel. Ron and I supplied helium from TH |

Tuesday, February 25, 2014, 10:00, David Wang, Conditioning Station, Repair, TM2, , helium pressure test on TM2 tube heater (+) water line with blank off(C-seal) installed on WB. 10x
|
I did the helium pressure test on TM2 tube heater (+) water line with blank off(C-seal) installed on water block at CS.The leak
detector was hooked directly to the top of the module this time. So base leak rate and base pressure were at the bottom scale on LD. 30 -80 psi helium
was applied to the D lines(both side) with10 psi increasing each time. There is no any tiny response hasbeen found during the test. The lines |

Tuesday, February 25, 2014, 06:53, David Wang, South Hot-Cell, Repair, TM2, , Leak check on TM2 tube heater (+) water line with blank off(C-seal) installed on WB.
|
Chad and I did the leak check on TM2 tube heater (+) water line with blank off and C-seal installed on WB at South Hot Cell.The
line was easy to pump down to 0.0xE-9atm.cc/sec and 0.0XE-4 torr on leak detector. Chad flushed lot helium around the water block (10 sec spray). No response
had been found on leak detector. |
