|
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 |

|
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 |

|
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 |

|
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 |

Tuesday, September 01, 2015, 14:54, David Wang, ITW, Standard Operation, TM2, , TM2 has been connectec in ITW.
|
TM2 has been connected in ITW. During the connection, Anders and I found the TM2 high current cables used in ITE and CS are short in ITW.
Anders and Grant found the original TM2 ITE high current cables in target hall. We replaced them. They works fine. But, a little bit longer on cable length
would be easy to connect them. All other connections and HV cover in ITW work for the TM2 so far. |

Tuesday, September 01, 2015, 10:38, David Wang, ITW, Maintenance, TM2, , ITW top tank flange clean up and r-ring replacement.
|
During last run， ITW dump circuit had a water leak on an adaptor below the pressure gauge. The top tank flange, slot, and O-ring were water contaminated
by the leak. I removed the old o- ring, cleaned up the flange and o-ring slot, and put a new o-ring into the flange. Some pictures will be attached
in this mail later. |
