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 |

|
The source tray for the mock-up has been setup for waterline bending and soldering/brazing.
Thanks to Travis for finding the photos for the TM3 rebuild that took place in the anteroom in 09' and Maico and Dan for the support in ironing
the issues with the source tray side soldering issues. |

|
| The source tray side of the water block jig has been removed in preparation for moving the module to the conditioning station for electrical tests. |

|
| the containment box has been reinstalled onto TM3. After electrical checks it is ready to move to the conditioning station...for electrical tests. |

Wednesday, May 15, 2013, 10:20, Bevan Moss, Conditioning Station, Repair, , , Roof top chiller failed
|
I have been getting a fault on the roof top chiller for the 2 tandem 7.5 ton chillers. I have checked and we have water flow and the temperatures are
nowhere near freezing. I believe they are over heating as the fans on that side are not coming on. The blades are free to turn by hand but the VFD controller
keeps saying off. I have tried turning it on and off and that also did nothing. I have contacted ESC for further advice. |

Wednesday, May 15, 2013, 10:25, Bevan Moss, Conditioning Station, Repair, , , ONICON flow meter
|
Scott Adair from Riada sales came to site to complete diagnostics on the ONICON flow meter. He could not determine the problem and believes that
there was a short in the head. He has taken the flow meter for what should be warranty repair. The flow meter is for diagnostics only, the conditioning
station can still operate without it. |
|
Wednesday, May 15, 2013, 16:21, Bevan Moss, Conditioning Station, Repair, , , BIAS Current readings off by a factor of 5
|
A special thanks to Kazuya, Jane and Ray who jumped on this issue right away! The limit of the BIAS PS was set as 20000uA when in reality it is
4000uA. The issue has now been corrected. Please remember to divide the current by 5 for any elogs older than this one. |
|
Wednesday, May 15, 2013, 17:32, Bevan Moss, Conditioning Station, Standard Operation, TM3, , TM3 in place but not connected
|
To confirm that the sparking was coming from the module rather than the conditioning station TM3 was grounded and the conditioning station biased.
Attached are the results. Highlights include that there was no sparking and the station was able to achieve 60kV (limited by controls from going higher).
The current from the raw file has been corrected by the required factor of 5. |
