 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 |

|
Work on TM3 source tray removal started at 10:40 am today.
The containment box has been removed, and disconnection of the optics tray is 90 complete.

Wednesday, April 24, 2013, 14:09, chad fisher, South Hot-Cell, Repair, TM3, , TM3 Refurbishment E.O.D.
|
Optics tray has been removed from module.
Waterblock jig installation has commenced. Of note, jig installation on TM3 has proven more dificult than the previous installation on TM2. Many
of the waterblock assemblies are skewed (not perpendicular to plane that they should be...perpendicular to). |

Friday, April 26, 2013, 11:20, chad fisher, South Hot-Cell, Repair, TM3, , Water Block Jig (back half)
|
The back half of the water block jig (services tray side) has been sucessfully located onto the module.
About 50% of the waterblocks have centered themselfs it their respective cups and the rest look good for concentricity but will require some gentle
wiggling to get them to seat. |

Friday, April 26, 2013, 14:31, chad fisher, South Hot-Cell, Repair, TM3, , TM3 refurb E.O.D.
|
Service tray side of the waterblock jig is installed and all locking tabs enagaed save the heat shield circuit. Locking tab for heat shield circuit with
be worked on Monday morning and installation of the source tray side of the waterblock jig should commence on monday as well. |

Monday, April 29, 2013, 15:58, Bevan Moss, South Hot-Cell, Repair, TM3, , Source Tray Removal
|
Chad removed the source tray from TM3 today, see attached picture (video was also taken). There was some interference between the window cooling
lines and the frame work as well as the clamps for the ground electrode and the water block alignment jig. There was also interference between the optics
alignment post (specifically the mushroom top) and the water block alignment jig. Investigation into these inferences needs to be completed as they could |

The source tray has sucessfully been removed from TM3.
I will put a report in the TM3 rev 3 docushare directory as there were some items of note during this procedure. |

Tuesday, April 30, 2013, 07:51, chad fisher, South Hot-Cell, Repair, TM3, , Coil line flow check
|
David and I checked circuits p and q (the water cooled coil ciruit) for flow this morning as, with the source tray still in the module, there was both
a leak and a leak tight blockage. Both p and q allowed air flow through them confirming that the blockage was in the surce tray side of the system.
The heat shield circuit was also tested for flow and it passed. |

Thursday, May 02, 2013, 10:09, chad fisher, South Hot-Cell, Repair, TM3, , Service tray water block leak check
|
David and I preformed a helium leak check on the service tray waterblocks and verify that no damage had been done during jig installation. All 14 circuits
were checked and verified to be ok except circuit E and circuit I which were unstable when helium was applied. The resonse time on E and I would suggest
that it is an issue with the bungs that were used and not the braze joint however. |

|
With the aid of nic new manipulator snap fingers made by Maico the peek cable ties restraining the 9 pin connector wiring to the gas lines have been
cut. |

Monday, May 06, 2013, 15:45, Bevan Moss, Conditioning Station, Repair, TM3, , 55 pin connector removed
|
Travis and I removed the 55 pin connector from the service cap today. The feed through was left in place as a new design for the replacement has yet
to be designed. It was not possible to test if the cables could be pulled easily as I believe there is still 1 cable tie in the containment box. The wires
were cut flush with the top of the copper tube in case Chad cannot remove them via the hot cell. Other items removed include several cable ties and a clamp |
