Monday, April 22, 2013, 11:35, Bevan Moss, Conditioning Station, Repair, TM3, N/A, TCS:DIF2 broken
|
The flow meter on the primary side (TCS:DIF2) of the conditioning station is broken. I investigated and there is flow, the gauge is not fouled,
and the PLC does read back when current supplied. The gauge is also reciving 24V but the output is 0V and 0mA. I will contact ESC and the supplier. |
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 |

Tuesday, April 23, 2013, 13:48, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, EL testing
|
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 |

Tuesday, April 23, 2013, 15:52, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, Further HV Testing
|
Further HV testing was completed today from ~2:00 until 3:00. The resistivity of the water was 11.7 - 12.7 Mohm. The EE was turned on to 1500 V
and had a leakage current of 1.465 mA with a inline and ballast resister of 20 kohm and 1 Mohm respectively. In addition to this all of the CB were turned
on to 500V. The voltage on the source tray with all bias items tied together and the voltage was then raised to 30kV in 5kV steps. It was then raised until |

Tuesday, April 23, 2013, 16:11, Bevan Moss, Conditioning Station, Maintenance, TM3, N/A, Chiller Fault 2
|
During Testing it was noticed that Fault 2 was indicated and one of the compressors would not run. Fault 2 does not indicate what the issue was
and during inspection nothing could be detected. It had something to do with TCS:CHILCP3 and possibly CP2. CP1 could still be operated and was controlled
manually to keep the temperature in the correct range. This was not required but it does affect the conductivity. The main power switch on the chiller |

Wednesday, April 24, 2013, 09:00, Bevan Moss, Conditioning Station, Development, , , New user testing
|
Controls has created a new user group that can operate the conditioning station but cannot use any of the bypasses or forces. The cooling package
will be used to test this new profile. The main loop bypass has been opened to allow this testing to happen without the risk of over pressure. |

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 |

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 |

|
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 |

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. |
