On Friday, June 22 the following work was carried out.
Further inspection of the source tray.
Testing of existing tray removal and installation tool...it works fine, there was
just a specific method for proper coupling to the target module. There was no documentation for this tool, so it took a little bit of insight with |

|
TM4 was successfully moved from the South Hot Cell to the South-West Silo remotely by Grant Minor, with help from David Wang and Don Jackson. The
move was without problems. See ISAC Work Permit 2012-12-04-1. |

Wednesday, April 17, 2013, 15:17, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, Turbo Pumps Failed
|
Both Turbo pumps on TM3 have failed. They were both attempted to start in soft mode. TP2 could only achieve ~19kpm and TP1 ~10kpm. I have
turned off the scroll pump and vented through the turbo pumps. |

Monday, April 22, 2013, 11:35, Bevan Moss, Conditioning Station, Repair, TM3, N/A, TCS:DIF2 broken
|
The flow meter on the primary side (TCS:DIF2) of the conditioning station is broken. I investigated and there is flow, the gauge is not fouled,
and the PLC does read back when current supplied. The gauge is also reciving 24V but the output is 0V and 0mA. I will contact ESC and the supplier. |

Tuesday, April 23, 2013, 11:19, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, HV Test All common
|
A HV test was conducted yesterday on TM3. There was no target and all items were tied to common or ground. The conductivity of the water ranged
from 7.1 to 7.5 Mohm. 40kV @ ~600uA without continuous sparking was achieved. The Strip tool was run but something went wrong with the export and the vacuum
gauge data is missing. I have attached the file for reference and the pulled data from the achiver (only logs every 300 seconds). RGA scans were taken |

Tuesday, April 23, 2013, 13:48, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, EL testing
|
This morning the Einzel Lens was tested on TM3 as the intention is to reuse this piece of equipment. The EL was able to achieve 39.9kV at ~1.35mA before
a major spark happened and the power supply turned off. Also during testing the penning gauge suddenly shot up after a spark, it did not recover and had
been acting strange in previous test, it was decided to ignore its value and continue testing but it should be replaced in the future. When I went to save |

Tuesday, April 23, 2013, 15:52, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, Further HV Testing
|
Further HV testing was completed today from ~2:00 until 3:00. The resistivity of the water was 11.7 - 12.7 Mohm. The EE was turned on to 1500 V
and had a leakage current of 1.465 mA with a inline and ballast resister of 20 kohm and 1 Mohm respectively. In addition to this all of the CB were turned
on to 500V. The voltage on the source tray with all bias items tied together and the voltage was then raised to 30kV in 5kV steps. It was then raised until |

Tuesday, April 23, 2013, 16:11, Bevan Moss, Conditioning Station, Maintenance, TM3, N/A, Chiller Fault 2
|
During Testing it was noticed that Fault 2 was indicated and one of the compressors would not run. Fault 2 does not indicate what the issue was
and during inspection nothing could be detected. It had something to do with TCS:CHILCP3 and possibly CP2. CP1 could still be operated and was controlled
manually to keep the temperature in the correct range. This was not required but it does affect the conductivity. The main power switch on the chiller |

Thursday, August 29, 2013, 17:16, Bevan Moss, South Hot-Cell, Repair, TM3, N/A, Heat Shield Repair
|
Today Chad entered the south hot cell on work permit 2013-08-29-3 to repair the leaking heat shield line. The heat shield line was removed from
the module and the surfaces cleaned. New C seals and spring were inserted and the line re-attached. During this time Chad also installed the new vacuum
gauge. Grant took video of this work and Keith some pictures. The video and pictures can be found on the M: drive (groups) in the RH folder. The total |
