|
Roughing started at 12:06. It was believed there was a problem with the compressed air but there was none, TM1 doesn't leak and so you cannot hear
that the connection is made. |

Wednesday, April 17, 2013, 15:17, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, Turbo Pumps Failed
|
Both Turbo pumps on TM3 have failed. They were both attempted to start in soft mode. TP2 could only achieve ~19kpm and TP1 ~10kpm. I have
turned off the scroll pump and vented through the turbo pumps. |

|
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 |
