| The roughing pump for TCS was started at ~3:00 and the turbo's turned on at ~4:00. This is the minimum time for the module to pump down. |

|
The filament on IG1 for TM3 was replaced by myself and Edi. The old filament did not appear to be damaged but the controller claimed it was. The
current gauge on TM3 is a single filament, ideally it would be upgraded to a double. |

Yesterday the TBHT was ramped to 250 amp and the TGHT was ramped to 440 amps. Attached is the data from that run the strip tool that had this screen
shot crashed but it can be recreated with the data. The TBHT ps was not reading back accurate results as such there are large steps in current or voltage
or some instability for no apparent reason. In addition to this the ramping program is still not working so the ramping was a very manual process. The |

Wednesday, October 02, 2013, 13:44, Bevan Moss, South Hot-Cell, Standard Operation, TM4, , Right Coil is leaking
|
Today Maico and Travis completed and electrical test to determine the right and left coil on TM4. The left coil is the negative side. From there
Maico pumped on both lines for a leak test. The leak cart pumped down to its lower limits on the left line and there was no response when sprayed with
helium. The right line would not pump below 2.5 x 10^-2 Torr and had a base leak rate of 3.3 x 10^-7 atm*cc/sec (this indicates a massive leak). Without |

|
Blocks 1-4 have been moved from ITW to ITE. Block 5 was moved to a storage area as it will be in the way of the harp repair. Danka took air samples
and found 200 counts of alpha on the air samples but nothing on the swipes. It is recommended that resporators be worn while blocks are being lifted and
lowered. She will check the monitor tomorrow to confirm it is behaving as it should. |

|
Yesterday I visually inspected the paddle wheel and noticed that it was spinning freely and constant. As the signal was intermittent replaced the
coil at the back of the wheel only. This does not require access to the high active water. With the coil replaced the signal looked strong. I asked operations
to keep and eye on it and advise if the problem has been resolved. I also discussed with David this morning and he informed me that this is the same procedure |

Monday, October 21, 2013, 12:29, Bevan Moss, Conditioning Station, Repair, TM4, , BIAS Canbus
|
There is something wrong with the BIAS canbus controller. It says that it is not alive and has timed out. I have tried unplugging it and plugging
it back in but that has not resolved the problem as it normally does. I have contacted Dave Morris and am waiting to hear from him. I cannot HV test without
this controller. |

| The base card in the canbus BIAS module was determined to be faulty. Dave Morris removed a card VECC to repair the conditioning station. |

Tuesday, October 22, 2013, 17:04, Bevan Moss, Conditioning Station, Standard Operation, TM4, , HV testing
|
This afternoon TM4 with the coil removed was tested with HV. The EINZEL LENS was first tested independently while the bias canbus was being repaired.
The current on the EL looked stable at 25kV for 5 minutes. At 27.5kV the current becomes unstable and occasionally sparks. This voltage was held for 30
minutes but the current did not appear to be becoming more stable. Further extended testing would be required to determine if this can be conditioned out. |

Tuesday, October 22, 2013, 17:07, Bevan Moss, Conditioning Station, Standard Operation, , , services shut down

| The turbo pump, roughing pump, have been turned off and the valves for venting opened. The cooling package has also been turned off. |

Tuesday, November 12, 2013, 10:59, Bevan Moss, South Hot-Cell, Standard Operation, TM2, , Electrical Test
|
Don Jackson and Myself completed started an electrical test on TM2. All lines passed the with OL to ground. When testing in between the lines individually
there were several lines that read other than OL. It was decided to abandon the testing as there were too many "failures". The results are attached.
The testing will be repeated in the conditioning station with vacuum. It is not expected that this will change anything as during a quick visual inspection |

Tuesday, November 12, 2013, 12:43, Bevan Moss, Conditioning Station, Standard Operation, TM2, , TM2 moved from SHC to TCS
|
TM2 was moved by myself and David from the SHC to the TCS. Move went well. Curiously the fields on the module were measured higher than the previous
measurement (now ~5.8mSv/hour) . |

Friday, November 15, 2013, 16:48, Bevan Moss, Conditioning Station, Standard Operation, TM2, , HV Testing
|
High voltage testing was started on TM2 with no source tray today. The maximum stable for 1 minute voltage reached was 47.5kV but the module is
still conditioning. With every step up in voltage the current goes up a large amount and slowly bleeds down. Large sparks disrupts the connection of the
CANBUS to the PS which is irritating but the module can be brought up to the equivalent voltage in less than 30 seconds. Attached is a screen shot of most |

|
This morning when I went to start HV conditioning CP2 and CP3 both had faults and the temperature of the water was ~27C. I reset the compressors
by flipping the system reset switch. This cleared the fault and allowed the compressors to come one. To the best of my knowledge these faults happen as
a result of compressor fluid pressure too low or high and temperature too low or high and lack of flow. The system cannot determine which one it was that |
