Monday, August 10, 2015, 14:07, Isaac Earle, South Hot-Cell, Repair, TM2, , TM2 Containment Box Removed
|
The containment box was taken off TM2 in preparation for installation of a new coil line isolator.
ITA6272 and ITA6273 have been received from the Scintillator Shop. ITA6274 should be ready by the end of today. |

Thursday, August 13, 2015, 09:17, chad fisher, South Hot-Cell, Repair, TM2, , TM2 status
|
Tuesday, August 11, insulator ITA6272 was installed onto the "pin x" line (unused plasma electrode) and tested; it seems to have successfully
eliminated the shorts on that line.
Wednesday, August 12 "shunts" installed on tube heater and oven circuit and electrically tested. |

Friday, August 14, 2015, 10:00, David Wang, Conditioning Station, Repair, TM2, , Started CS water package for TM2
|
| I finished the rest TM2 connections to CS, and started CS cooling package. Everything works fine so far. |
|
Wednesday, August 19, 2015, 14:52, David Wang, Conditioning Station, Repair, TM2, , TM2 at CS
|
During the TM2 HV test at CS, It failed. In order to confirm there is no any water leak inside the module after the heaters and beam extraction test,
I disconnected all the water lines on the TM2, and purged the water lines with pressure air. Leak detector was reconnected back to the TM2 service cap,
and all water lines are pressurized with 80psi helium again each for 2 minutes.No any leak had been found during the test. All the water lines are still |

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. |
|
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. |

Thursday, September 10, 2015, 08:55, chad fisher, South Hot-Cell, Repair, TM1, , TM1 Window Leak Diag.
|
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 |

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 |

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 |

Thursday, September 17, 2015, 11:50, David Wang, Spent Target Vault, Repair, TM1, , TM1 window circuit leak check
|
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.
