Tuesday, May 10, 2022, 11:26, Nadia Jorgenson, Cyclotron, Repair, Festooning rail rope and pulley system re-routed
|
The rope and pulley system that is used to raise the festooning rail across the vault shield door has been re-routed. It now makes use of all three pulleys
and is easier to raise and lower without interference. |
Tuesday, May 10, 2022, 11:30, Nadia Jorgenson, Cyclotron, Repair, Cracked Festooning Rail Bushing Removed 
|
We removed the left bushing that is around the air cylinder on the festooning rail, right outside the cyclotron. It was cracked. Will need to replace
next year when the vault door opens again. |

Tuesday, May 10, 2022, 11:31, Nadia Jorgenson, Cyclotron, Standard Operation, Vault Shield Door Closed
|
The vault shield door has been closed and seal inflated. The operation was performed with
no issue. |

|
During the 2023 shutdown outrigger 1 failed. While performing the HE Probe removal we found
that the outrigger could only travel vertically about one inch in each direction. |

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 |

Tuesday, November 14, 2023, 12:38, Nadia Jorgenson, Service Bridge, Maintenance, Bridge Orbit Counter Work in 2023
|
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. |

|
Remote Handing is ready for January, 8 2018 Cyclotron lid up. Elevating system service has been completed.
A Cyclotron Lid raise was attempted on Monday, January 8 at 12:00, however this attempt was aborted after lifting the lid several millimeters due the motor

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. |

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: |
