Checks of the wiring for the IMG are complete and have passed.

  334   Thursday, May 09, 2013, 10:13 chad fisherSouth Hot-CellDevelopment  Mock-up Progress

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.

HS had been purged. The ITE is under venting. The TM4 will be moved to SH on next Tuesday which is May 21th.

  345   Wednesday, May 15, 2013, 10:20 Bevan MossConditioning StationRepair  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.

  346   Wednesday, May 15, 2013, 10:25 Bevan MossConditioning StationRepair  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.

 

 

  347   Wednesday, May 15, 2013, 16:21 Bevan MossConditioning StationRepair  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.

  349   Wednesday, May 15, 2013, 17:32 Bevan MossConditioning StationStandard OperationTM3 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.

Manipulator has been sucessfully repaired. Recieved 0.19 mSv. Took Approx. 10-20 minutes

TM#3 with no target or source trays has been moved from the conditioning station to the NE silo.

  359   Thursday, May 23, 2013, 14:07 Bevan MossConditioning StationRepair  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. 

  361   Thursday, May 23, 2013, 14:12 Bevan MossConditioning StationMaintenance  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).

  363   Monday, May 27, 2013, 10:37 Bevan MossConditioning StationMaintenanceTM4 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.

  364   Monday, May 27, 2013, 11:55 chad fisherSouth Hot-CellStandard 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.

  365   Monday, May 27, 2013, 15:59 Bevan MossConditioning StationRepair  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.

  366   Monday, May 27, 2013, 16:01 Bevan MossConditioning StationRepair  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.

Dan an I  transferred 5 shielding blocks from ITW to ITE. The ITE is configured to take proton beam.

  375   Tuesday, June 04, 2013, 15:34 Bevan MossConditioning StationRepair  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.

Dan and I  disconnected TM1 in ITW.
