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. |

Friday, October 25, 2013, 06:58, David Wang, South Hot-Cell, Standard Operation, TM4, , Leak check on TM4 target heat shield
|
Maico and I leak checked HS circuit after Chad installed the target. The circuit was a little bit difficult o pump down because of residue water moister
inside. But once the moisture was pumped out, the pumping down was smooth and fast. The base leak rate 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr.
Maico checked helium flow before the leak test. Then,He sprayed helium to all 3 VCR fiitings on target with 2 seconds on each one, He also flushed 10 seconds |

|
TM2 is now in the hot cell with the containment box off for inspection and eventual blank off off the water blocks.
Upon initail inspection the status (fron a hot cell point of view) is:
-Water block jig is equipped/on |

The old thermocouple wire has been sucessfully removed from the module.
Thanks Bevan, Travis and David. |

| Bevan and I installed 2 turbo pumps on TM2. The o- ring flanges on TM2 had been cleaned before the installation. |

Tuesday, November 12, 2013, 09:51, David Wang, ITE, Standard Operation, TM3, , TM3 disconnection
|
TM3 has been disconnected this morning and purged all HV water lines. I found the power plug for all turbo pump fans wasnt connected during
the last run. That maybe the one of the reason on that ITE TP3 failure. |

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) . |

Wednesday, November 13, 2013, 10:01, David Wang, Conditioning Station, Repair, TM2, , TM2 leak check at conditioning station
|
I leak checked TM2 at conditioning station this morning. All air to vacuum seals on the top of the module are good. All water lines are pressured with
60 psi helium for minutes each. One of the tube heater + water line( 2lines for tube heater + for supply and return) has a huge response on 60 psi helium
pressurizing. The leak rate went from 6.0xE-9atm.cc/sec to maximum leak rate in 5 seconds and I saw a pressure increasing either. when I pressurize the |

Thursday, November 14, 2013, 08:08, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Blank off and jig removal
|
Firday, November 8 all water blocks (excluding I and K) were blanked off and vacuum leak checked. No responses were found. (First Picture)
I and K could not be blanked off without removal of the water block jig. Also, I dropped one of the blank offs onto the table, so one line could
not be blanked off until a new clean blank off was inserted into the cell. In addition, there was still reminace of a bolt in block Ias it aslo could not |

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 |

Monday, November 18, 2013, 11:54, Bevan Moss, Conditioning Station, Repair, TM2, , Fault on TCS Chill
|
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 |
