|
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. |

|
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. |

|
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, 10:17, Bevan Moss, Conditioning Station, Standard Operation, TM3, No Source Tray, Preliminary Results from HV testing 
|
Testing on TM3 without a source tray was completed on 13/05.2013. All items were tied to common and the water blocks were left open at the bottom
of the module. They were left with the quick connections at the top. The vacuum was in the low 10^-6T range so this was deemed acceptable. The cooling
lines withing the cage in the target hall were shorted so flow could continue. As you will see from the results a maximum of 44kV was achieved before a |

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 |

|
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 |

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. |

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 |

|
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. |
