|
The uncovered VA8 section of beam pipe was surveyed in preparation for a visual inspection and some laser scanning.
Fields around the East and West elevated ledges of the beam pipe were around 100 uSv/hr. The pole monitor registered around 2mSv/hr on contact
with the beam pipe indium joints. |

Monday, February 10, 2025, 16:52, Albert Kong, Standard Operation, Target 1, Cooling, T1\T2 Cooling Packages Refill and Restart 6x
|
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. |

Monday, February 10, 2025, 16:46, Albert Kong, Maintenance, Other, Other, T1 T2 ASCO Air Solenoid Valve Rebuild
|
The compressed air ASCO valves for the M9BB, M20BB, T1 Profile Monitor (2x 8342C1 [rebuild kit 306-191] + 1x 8320G216 [rebuild kit 314-949] respectively),
and T2 Profile Monitor (8320G216) were serviced with their rebuild kits.
To service these valves, we isolated them from the compressed air source by shutting off the outlet valves on the air amplifiers and venting the |

Thursday, January 23, 2025, 17:09, Albert Kong, Maintenance, Other, Cooling, T1 T2 water solenoid valves rubber gasket and o-ring exchange
|
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 |

Thursday, January 23, 2025, 16:58, Albert Kong, Maintenance, Other, Cooling, T1/T2 CUNO filter exchange, hansen fitting inspection, T2 FGSEC proteus electronics replaced, T2 FGSEC and Q1 paddle wheel replaced
|
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. |

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 |

The following maintenance tasks were completed on 2024-11-29 by A. Newsome, A. Kong, A. Tam, M. Dalla Valle:
Warm cell right window water level topup... the water level was a couple inches lower from the top. Using a tube connected to the nearby
sink, the level was topped up fully. See attached before/after picture.
Hot cell oil level checks:
Right side OK. |

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).

|
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 |

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. |

Thursday, August 22, 2024, 15:16, Adam Newsome, Standard Operation, Other, Active Sump, Active sump filled ~600L with grey water from RCR1 sump replacement
|
During a replacement of the RCR1 active sump (mechanical services group), approximately 600L of non-active grey water was released into the RH active
sump. At this time, this should be all of the water in the RH sump (approximately 600L total). |

Tuesday, August 06, 2024, 11:35, Albert Kong, Standard Operation, Other, BL1A Holding Tank, BL1A and RH Active Sump Draining
|
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 |

|
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. |

|
At ~8am on May 06, the expansion tank level sensor for the T2 cooling system suddenly became noisy.

|
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. |
