 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. |

|
Spent target SiC#28 (RFQ Target) has been moved from the south hot to the storage vault. The target was placed in pail #105 in spot 2C of the spent target vault. The target had a field of 24.8mSv/hr at about a meter upon removal from the south hot cell. See attached PDF for the status of the vault. It currently only has six free spots left. |

|
The HV conditioning reached a maximum of 44kV today before a spark took out the canbus card. I will attach the data once I have had a chance to format it. |

|
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. |

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. |

|
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). |
