Wednesday, April 24, 2024, 14:26, Adam Newsome, Elevation Jack, Standard Operation, Lid up operation (second) - 2024
|
Due to an issue with resonator latching, there was a need to raise the cyclotron lid a second time this shutdown.
The plan at first was to raise the lid by small increments (approximately 1mm at a time up to approximately 25mm) while RF group performed some
checks. |

An issue was encountered on 2024-02-23 when attempting to operate the lift trolley.
The following symptoms were observed: |

Friday, February 16, 2024, 11:11, Adam Newsome, Trolley, Repair, Lift Trolley: vertical motion failure, motor relays replaced
|
Today (2024-02-16) when operating the lift trolley to install shields in the cyclotron, the vertical motion was observed to be intermittently working.
When the trolley was out of the cyclotron tank and on the carrier, troubleshooting showed that it was likely an issue with the motor relays. The relay
box was removed and the relays showed signs of wear due to ageing. The relays were replaced with new ones, and the box was reinstalled. The vertical motion |

The cyclotron lid was raised starting ~10:30am on 2024-02-06 and finishing at ~3:30pm on 2024-02-08, under work permit C2024-02-06-4.
Upon first attempt to raise the lid, issues were encountered. The system seemed to start as expected but quickly tripped, resulting in no appreciable |

Thursday, February 08, 2024, 08:50, Adam Newsome, Elevation Jack, Maintenance, Elevating system - station 10 motor contactor issue
|
It was observed during lid up operation on 2024-02-08, approximately halfway through raising the lid, that the motor contactor for station 10 located
within its small motor panel stopped functioning. The symptoms observed were: entire system stopped since station 10 lagged behind (approx. 150 counts
on counter), station 10 could not be jogged locally in either direction, the control signal to activate the motor was being sent to the contactor when |

Wednesday, February 07, 2024, 12:04, Adam Newsome, Elevation Jack, Repair, Elevating system - brake master relay fuse issue
|
It was observed when attempting lid up operation on 2024-02-06 that the brakes for each of the jacks were not operating correctly. It appeared that power
was not being applied so the brakes were stuck in the engaged state. This ultimately resulted in issues with the lid up operation.
The issue was traced to relay A1 (the master brake power relay) not toggling as expected, despite the relevant control signals being present to |

Wednesday, January 31, 2024, 11:39, Adam Newsome, Elevation Jack, Maintenance, Jack station 11: synchro replaced
|
Because of observed noise on the synchro at jack station 11 during recent shutdown lid up/down operations, the synchro at this station was replaced on
Jan. 31, 2024. The procedure in Document-234859 was followed.

Tuesday, January 23, 2024, 14:03, Adam Newsome, Elevation Jack, Maintenance, Inspection of elevating system motor contacts
|
Motor contactors for the cyclotron elevating system jacks were inspected on 2025-01-23 by Joel Semilla under work permit C2024-01-19-1.
Joel's assessment is as follows:
"All the twelve magnetic contactors have the same contact tips condition. Last year, I have [sic] to take out the contacts from the housing |

|
All the bearings on both the upper and lower wheel were replace to see if it will improve
the accuracy of the orbital position reading. See drawing SK-2489 for list of bearings used.
The encoder was also replaced to match the style used elsewhere. |

Tuesday, November 14, 2023, 12:13, Nadia Jorgenson, Service Bridge, Repair, First Festooning Car "H" channel replacement
|
Damaged "H" channel removed from the first festooning car, and spare channel was put in place.
Note: it seems like the aluminum channel is not strong enough for the forces its being put under, and is resulting in deformations (See picture
"Festooning car H channel deformation"). We suspect this has happened in the past, notches were cut out where the deformation likely occurred |

Wednesday, October 18, 2023, 12:35, Jason Zhang, Service Bridge, Development, O503 Bridge and Outrigger integration testing
|
Service bridge, Outrigger #1, and Outrigger #2 have had the controls system migrated to PLC controls. The 5069-AENTR control unit is located at
the centrepost and will be mounted there after wiring is cleaned up. Preliminary testing consisted of operators simulating a shutdown task was performed
today and was a success. Minor adjustments to the encoder logic will be made before the commissioning test. The follow tests were done: |

|
The mirror actuation mechanism was observed to be "sticky" during 2023 winter shutdown - it occasionally did not function properly and needed
some manual assistance.
The following items were addressed to resolve the issue: |

Thursday, September 07, 2023, 13:21, Jason Zhang, Service Bridge, Development, Outrigger #1 and #2 individual testing complete
|
Outrigger #1 and #2 have had their controls system overhauled as part of the O503 project. The previous controls enclosure and the elements have been
replaced with a new aluminum enclosure which contains DIN rail relays, a 5V power supply, and a +-12V Power supply. The new centrepost slave PLC unit handles
the control logic of OR1, OR2, the Bridge and is connected to the main PLC in the control room through Ethernet. Both outriggers were tested individually. |
