 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.  See attachments

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

Entry  Tuesday, September 15, 2015, 11:06, chad fisher, South Hot-Cell, Repair, TM1, , TM1 Window Gasket Replacement 

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 seconds waiting time , the LD started to show leak up to 3xe-9atm.cc/sec.

Chad sprayed helium close to service tray and vacuum chase. with 1second click on helium , after 30 seconds waiting time, the LD started to show leak up to 2Xe-8 atm.cc/sec.

After this test, we knew the leak is somewhere in service tray or service cap, but not the soldering stems in containment box we suspected before.The further investigation is needed.

Entry  Tuesday, September 15, 2015, 08:24, David Wang, South Hot-Cell, Repair, TM1, UCx 13, Leak check on TM1 window circuit soldering stems in service cap. 

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 from SHC helium spray which LD climbed to 1.4xE-8atm.cc/sec with only one click helium spray by Chad.

 Because of the high air flow at SHC when the round panel is removed, The result is not conclusive. The same test is done at silo without  airflow. We found a big leak on this soldering stems . See later e-log.

Entry  Thursday, September 10, 2015, 08:59, chad fisher, South Hot-Cell, Repair, , , Manipulator Mait. and field check Sept. 4 

Hot cell was entered for preventative mait. on left manip. field measurements around the cell were taken in prep. for window removal in January and left/south light bulb changed.

Hottest item in the cell was the conductor block end of the TM4 febiad coil line. It was 70 mSv/H on contact and seemed to be the major source of field in the hot cell. The waterblock end of this line did not apper to be hot.

Vacuum leak check on the window line circuit of TM1 took place yesterday and again to confirm this morning. Both days the response to helium is in the area of a soldered reduction fitting at the top of the containment box above and to the shutter side of the extraction column (see attached picture). To verify this morning each joint in the system had a 1 second shot of helium and then timed for 1 minute to wait for a response. This area responded both times tested at about 40 seconds...no response at any of the other locations.
