|
Monday, December 08, 2014, 14:00: Dan M and Anders connected the water supply to circuit D and installed the module cover.
Monday, December 08, 2014, 14:50: Circulating water on circuit D. IG1 vacuum stable at 3.1E-7 T. No response on mass 18 on RGA
Monday, December 08, 2014, 15:30: Test TGHT and TBHT PS. Can be switched on, but set points need to be corrected. |

|
NOTE: If there is a problem with the chiller unit (ie Fault 1 or Fault 2), a power cycle may reset the VFDs for the fans and clear the problem.
To do so it is necessary to wait long enough for the VFDs to power off completely. The display will first start to flash before going dark. Wait another
few seconds before powering the system back up. The chiller unit is located on the ISAC I Penthouse Roof. |

A contractor on site today for chiller maintenance. CP2 and CP3 circuit is leaking and shall not be used. CP1 can still be used. The contractor will
contact Plant Group with a quote for repair and upgrades. |

Thursday, May 23, 2013, 14:07, Bevan Moss, Conditioning Station, Repair, , , Chiller Unit Repaired
|
ESC came today and "repaired" the chiller. There was something wrong with the VFD controller. The were able to get it to start and run
correctly again but were not able to recreate the problem. At this point it appears that it has magically disappeared. |

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 |

Tuesday, August 06, 2019, 01:13, Carla Babcock, Conditioning Station, Repair, TM4, Dummy HP SIS target, Checks on EE line leak fix and window line leak (not fixed)
|
TM4 has developed 4 leaks so far:
Line B - seems to be solved with an indium gasket (some testing already done)
Line D - seems to be solved with an indium
gasket (some testing already done)
EE - indium gasket installed, preliminary tests are good
Window cooling line - David found |

Thursday, September 28, 2017, 15:34, Anders Mjos, Conditioning Station, Development, TM2, , Changes to MP3 startup
|
Due to problems with the regulating valve WPV1, the VFD (Variable Frequency Drive) for the pump has been programmed to do a slow (2 min) ramp up.
WPV1 has been bypassed and left fully opened. Work was done by Dave Morris |

Wednesday, July 05, 2017, 11:18, Anders Mjos, Conditioning Station, Maintenance, TM4, Ta#52, Changed electrical configuration to cathode bias
|
| John Chow configured TCS to cathode bias mode (IRH1538). The anode P/S is in positive mode. |

Monday, January 16, 2012, 09:30, David Wang, ITE, Maintenance, , , Changed all old inducion coils for flow sensors in ITE
|
I had changed all old induction coils for flow sensors in ITE .I checked all ITE water signals on control boards in electrical room.They are all very
stable and constant.All ITE inductions coils work fine now. |
|
Thursday, January 24, 2019, 10:34, David Wang, ITW, Maintenance, , , Changed 24VDC plugs of TP solenoid valves in ITW
|
| 3 damaged 24VDC plugs of TP solenoid valves are replaced. Inspected other plugs. All of them are in good condition now. |

Wednesday, November 14, 2012, 11:04, David Wang, ITE, Repair, TM4, , Change ITE dump water circiut flow wheel
|
I changed ITE dump water circuit flow wheel due to its poor performance. The new flow wheel works fine. The signal on electrical board is strong and
constant. One shielding block on ITE was moved out for the job, and it has been moved back after the job.The ITE is ready to take proton beam. Travis was
with me when i did the job. |

Wednesday, September 28, 2022, 12:58, Matthew Gareau, North Hot-Cell, Repair, , , Chad repaired the right operator side manipulator
|
On 26/Sept/2022
Chad disassembled the right operator side manipulator, and noticed that gears in the handle were quite tight especially when compared to the left
operator side manipulator. |

|
On drawing ITA6008 for the Encole 0.5" ceramic standoffs there is a note to match pairs of ceramics to within +/-0.001". This step was missed
on the current build of TM2 source tray (ceramics were not measured).
Measured the lengths of the rest of the ceramic standoffs in inventory and they range from 0.5035" to 0.4950" in length. The ceramics |

Decon/removal of large solid waste was performed on Wednesday November 18th."Hot" activated items included containment box cover from TM2,
Febiad coil line remnants from TM4 (the hottest ends were previously cut off and disposed of), some target conductor bolts, steerer plugs from TM2, target
material remn. |
