|
I did a leak check on TM1 window circuit 2 soldering stems in service cap.The round side panel was opened for the job. I sprayed helium on
the stems for 10 seconds. The leak detector got a tiny response(from 0.0xE-9 atm.cc/sec to 2.0xE-9 atm.cc/sec). The test repeated again. The second
time, LD climbed to 1.2xE-9atm.cc/sec. It looks like there is a very tiny leak on the stems soldering spots. But , this is not the same leak we found |

|
Replaced the custom silver gaskets on the entrance window panel of TM1 this morning...this has eliminated an sign of leak at this joint, however there
appears to still be a leak somewhere...a good distance from the vcr joints of the window as we are getting a drift response.
Chad sprayed helium to soldering stems in containment box which we suspected with leak last week. With 1second click on helium, after 80 |

|
Leak check TM1 window circuit soldering stems inside service cap when module is located at NE silo. LD base LR 0.0xE-9atm.cc/sec. Only 1
second tiny amount helium sprayed on stems soldering joints . LD got a quick response to high E-7 atm.cc/sec.Test is repeated again with same result.

Tuesday, March 29, 2016, 08:38, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 water lines helium pressure check at TCS
|
TM1 water lines helium pressure check at TCS is done. 70 psi helium was applied to water circuits. Leak detector base leak rate 0.0 x E-9 atm.cc/sec,
base pressure 0.0 x E-4 torr. The result shows as below:

Friday, April 01, 2016, 13:58, Travis Cave, Conditioning Station, Standard Operation, TM1, UC#15, module moved
|
| TM#1 has been moved from the conditioning station to the south hot cell, had UC#15 installed and then moved back to the conditioning station. |

Friday, April 01, 2016, 14:41, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 and TCS vacuum system has been connected. TCS control page white out.
|
I can not start the TCS pumps due to control page white out. Control group is working on this issue.
Control group fixed the white out problem. I started all turbo-pumps. The pumping down is good so far. The TM1 IG1 is broken. I will check it on
next Monday. It could be a broken filament. Then, the filament will be replaced. |
