The following tasks were performed:
All electrical, water, and pneumatic connections to the T1 target was reconnected.
3x and 2x CUNO filters for T1 and T2
respectively were changed (O-ring for the housings were not changed).
All hansen fittings on the front mounting plates of the T1 and T2 cooling |
Monday, January 15, 2024, 16:36, Albert Kong, Standard Operation, Target 2, Cooling, T2 Resin Flask Exchange 
|
The resin flask on the T2 cooling package was exchanged today (new resin can prepped in the morning).
The newly installed resin flask was placed slightly off-set from the marking on the platform to ensure that the braided hose will clear the blocks
when replaced at the end of shutdown. |

Monday, January 15, 2024, 16:47, Albert Kong, Standard Operation, Other, Cooling, T1/T2 Cooling Pkg. Prep for Refill + Leak Check At Pressure 7x
|
The following tasks were completed in preparation of re-filling the T1 and T2 cooling packages:
All valves were returned to the 'open' configuration (note, compressed air to collimators at T1 is to remain closed - rotating collimator
no longer in use || also note, odd handle configuration at T1 panel when all valves are open - see attached).
Leaks from valves were checked, |

|
The following tasks were completed:
Yesterday (Jan 18), the T1/T2 cooling packages were inspected for leaks and some moisture was found underneath the CUNO filters behind
the resin cans on both T1/T2. It was determined that the source of the leak was a loose fitting on the drain valves of the CUNO filter housing (see photo). |

Thursday, February 01, 2024, 11:14, Albert Kong, Standard Operation, Target 1, Hot Cell, T1-MK1 Flush and Purge on Hot Cell
|
The recently removed T1-MK1 target ladder was flushed with city water for ~30s at all target positions. It was then purged with compressed air at ~5
psi for ~1 minute at all target positions. We then left the target ladder in pos5 to fully extend the bellows and allow it to dry overnight.
This ELOG will be updated as we progress with work done to dry the target ladder and eventually exchange the spent targets. |

Thursday, February 01, 2024, 11:16, Albert Kong, Standard Operation, Other, Cooling, Spent resin can rinse, purge, and drying
|
The recently removed resin can from the T2 target station was rinsed with city water and flushed with compressed air for 1 cycle.
We will run it through a few more cycles before proceeding with drying under the fume extractor, at which point this ELOG will be updated.
UPDATE (Feb 08, 2024): The T2 resin can underwent 3 more air cycles. Today it was moved under the fume extractor with the lid cracked open and |

Thursday, February 15, 2024, 14:53, Albert Kong, Maintenance, Target 2, Air amplifiers, T2 Lower Air Amplifier Maintenance/Rebuild
|
The lower amplifier for the T2 target station air supply was removed for teardown, inspection, and rebuild.
The goal of this operation is to understand wear development in the air amplifier over ~13 years of operation, and potentially determine a recommeded
service interval. |

Tuesday, May 07, 2024, 13:21, Albert Kong, Repair, Target 2, Cooling, T2 Cooling System Expansion Tank Ultrasonic Level Sensor Repair
|
At ~8am on May 06, the expansion tank level sensor for the T2 cooling system suddenly became noisy.
Cyclotron fault ref: 16915
Approximately 11:00 am today, the noisy sensor was replaced with a spare, upon which it was learned that the spare sensor is broken (registers |

Thursday, May 23, 2024, 17:10, Albert Kong, Standard Operation, Target 1, Target, T1-MK1 Target Exchange (+ leak fix, service panel changes, coupler exchange) 36x
|
On May 23, 2024 two sets of plugs from position 1 and 3 and a 12mm Be target from position 5 (serial #109) was removed from T1-MK1 in the Meson Hall
remote handling hot cell.
The plugs and spent target are kept in the secondary hot cell (East) on the lift table for future beamspot imaging and to cool down prior to disposal. |

|
The RH active sump was drained (over Jul 31-Aug 01), in total approximately 5500 L of water was sent to city sewage.
We also tried to divert water from the BL1A holding tank to the active sump, and learned that we cannot run back-flow through the sump pump. The
valving configuration used here was V10, V1, SV1, V6 open - V2, V3 closed. (Note solenoid valve SV1 does not serve a purpose and energizing/powering-down |

Monday, September 09, 2024, 09:39, Albert Kong, Other, Target 2, Cooling, B1A:T2CS:FGSEC:RDFLOW noisy, CYCLOTRON Fault 17321
|
Secondary flow sensor B1A:T2CS:FGSEC:RDFLOW on the T2 cooling station suddenly became very noisy at around 11 pm, 01 September 2024.
The sensor reading would fluctuate from 0-150 gpm which is beyond typical noise levels for these sensors (~2gpm).
The noise spontaneously ended at around 4 am, 05 September 2024. |

|
The active sump high level sensor was tested and correctly alarmed locally. However the alarm in the MHESA RCR lab did not make any sound and no notification
was recieved at the main control room. After some investigation, it is believed that the RCR lab alarm 'had already produced a notification at the control
room and so no new notification was produced by testing the remote handling sump. Alternatively, the RCR sump alarm may have been silenced in the control |

|
T1-MK1 electrical checks were completed on the hot cell. Specifically the profile and protect monitors were checked (assistance from Micheal Donohoe
and Holden Jones from 'probes group'/accelerator systems).

Friday, January 10, 2025, 18:36, Albert Kong, Standard Operation, Other, Cooling, T1/T2 cooling packages drained
|
The T1 and T2 cooling packages were drained starting at 14:36, by 14:48 both expansion tanks had dried, meaning the draining rate for both tanks were
~80L/hr, generally it will only take 2 hours to fully drain the system.
Tritium samples were collected after allowing the system to drain for ~5 minutes to clear out water in the drain lines and actually collect samples |

|
All CUNO filters at T1 was exchanged on Jan 17.
At the time, access to the CUNO filters at T2 was obstructed by a shielding block, we will exchange these filters once the block is moved.
All Hansen fittings on the target station were inspected, all o-rings found to be in good condition. |

All rubber components on the T1 T2 water solenoid valves were exchanged on Jan 22, 2025.
To service the heat exchange water and all collimator solenoid valves, the low active copper supply line in the 1A tunnel had to be shut off (see
pictures). Note that the shut off for the T2 secondary water did not work perfectly, it is possible that there either the valve was not shut off properly |

The T1 cooling package was refilled to ~38cm and restarted. Shortly after restarting reservoir level dropped and settled to 37.8cm.
No visible leaks when viewed from the Meson Hall south walkway,level seems steady after ~1 hour of operation, water conductivity also returned
to normal after a few minutes of flow. |
