|
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. |

Thursday, May 09, 2013, 14:23, chad fisher, South Hot-Cell, Repair, TM3, , Water Block Jig Removal
|
| 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. |

Friday, May 10, 2013, 09:26, chad fisher, South Hot-Cell, Repair, TM3, , Containment box reinstalled
|
| 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, 10:00, David Wang, ITE, Standard Operation, TM4, , Disconnected TM4 in ITE.
|
| HS had been purged. The ITE is under venting. The TM4 will be moved to SH on next Tuesday which is May 21th. |

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. |

|
| TM#3 with no target or source trays has been moved from the conditioning station to the NE silo. |
|
Thursday, May 23, 2013, 14:07, Bevan Moss, Conditioning Station, Repair, , , Chiller Unit Repaired
|
ESC came today and "repaired" the chiller. There was something wrong with the VFD controller. The were able to get it to start and run
correctly again but were not able to recreate the problem. At this point it appears that it has magically disappeared. |
|
Thursday, May 23, 2013, 14:12, Bevan Moss, Conditioning Station, Maintenance, , , Primary Circuit Drained and Flushed
|
Rob Walker has drained the primary side of the conditioning station. It will be flushed, filled and chemically treated. It was desired to
chemically treat the primary side before before but it took so long that sediment was found (things started to grow). |
|
Monday, May 27, 2013, 10:37, Bevan Moss, Conditioning Station, Maintenance, TM4, , Cooling Systems topped off
|
Rob walker has flushed and refilled the primary side of the system (note the water still looks nasty). This morning the primary side of system needed
to be bled as there were air pockets. Also TK2 had reached its low point and needed to be topped up. |

Monday, May 27, 2013, 11:55, chad fisher, South Hot-Cell, Standard Operation, , , Special Tooling for RFQ target
|
The special tool made for the RFQ target autopsy has been inserted into the hot cell.
4-40 button head screws have been successfully lossened. |

Monday, May 27, 2013, 15:59, Bevan Moss, Conditioning Station, Repair, , , Compressor fault
|
Once again the 7.5 compressors are tripping due to faults. I believe it is due to over pressure as a result of the chiller fans not coming on.
I have contacted ESC. |
|
Monday, May 27, 2013, 16:01, Bevan Moss, Conditioning Station, Repair, , , CanBUS card
|
During HV conditioning of TM4 with Ta#40 there was a spark at ~43 kV that caused the Bias card to "fry". Dave Morris has been contacted
and has said he will replace it tomorrow. |

Tuesday, June 04, 2013, 12:36, David Wang, ITE, Standard Operation, TM4, , 5 shielding blocks are transferred from ITW to ITE
|
| Dan an I transferred 5 shielding blocks from ITW to ITE. The ITE is configured to take proton beam. |
|
Tuesday, June 04, 2013, 15:34, Bevan Moss, Conditioning Station, Repair, , , Relay replaced
|
ESC was called out again to inspect the chiller as it was showing the same problem as before. This time when started one fan came on (this is not what
happened last time) but the fan controlled by the VFD did not. It was eventually traced to a relay that has been replaced. The system was tested as best
it could without a load and appears to be working. It will be difficult to tell until a heat load is in place if the fix has solved everything. |

Tuesday, June 11, 2013, 10:05, David Wang, ITW, Standard Operation, TM1, , Disconnected TM1 in ITW.

| Dan and I disconnected TM1 in ITW. |
