SiC#31 has been removed from TM4 and UCx#13 installed. UCx#13 connection to the 9 pin connector was VERY VERY tight to the tube heater insulator on both
the test jig and module.

|
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. |

|
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 21, 2015, 11:38, Anders Mjos, South Hot-Cell, Repair, TM2, FEBIAD Test Target, Steerer wires found to be touching the gas lines
|
Yesterday TM2 was inspected in the SHC. Spark marks were found both on the steerer wires and on the ANODE wire. The steerer wires (GND) were touching
the gas lines (60kV). This is likely the cause of the sparking observed at the Conditioning Station (e-log).

Hello all,
TM2's first performance in the Conditioning Station with the new source tray was not great, with sparking and HV degradation beginning to occur |

|
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 |

|
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 |

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 |
