 Tuesday, February 08, 2022, 11:39, Adam Newsome, Cyclotron, Development, Radiation Survey - sampling rate error
|
When attempting to perform the radiation survey, the program displayed an error at startup stating that the software was not able to keep up with the
incoming hardware samples, and suggested to increase sampling rate or buffer size. The default sampling rate of 500 ms was not used - rather, 100 ms was
used. No issues were observed with this rate. As far as I am aware, this issue had not occurred in the past, and the cause is unknown. |

Monday, February 03, 2020, 11:06, Adam Newsome, Cyclotron, Development, Porthole Cover Handling Tool - Initial Test Report
|
The suction-cup based porthole cover handling tool (TRH1366) was tested for the first time inside the cyclotron as part of the regular porthole cover moving
task (Jan. 29, 2020). The tool was operated by Adam Newsome and Travis Cave.

Friday, February 02, 2018, 14:14, Don Jackson, Trolley, Repair, Overcurrent on radial drive motor
|
Lower resonator trolley radial motor overcurrent was causing control system to drop
out momentarily. All controlled devices acted as expected and reverted to their fail-safe mode. |
|
Wednesday, June 12, 2024, 10:35, Riley Sykes, Trolleys serviced, Maintenance, Outriggers 1 and 2 Service
|
1,2 and 5 Year service completed. Vertical ball screws and chains inspected and regreased with Chemours Krytox EG 2000 suitable for vacuum and
clean room situations. Mechanically sound, will do a once over before next shutdown period. |
|
Friday, May 31, 2024, 11:28, Riley Sykes, Service Bridge, Maintenance, Outrigger mechanical inspection
|
Both outriggers were inspected and were found to be mechanically sound. No damage to components or hardware visible, will revisit with pre-inspection
before shutdown period 2025. |
|
Thursday, October 31, 2019, 14:31, Adam Newsome, Service Bridge, Repair, Outrigger 2 Vertical Drive Repair
|
Outrigger 2 vertical drive repair is complete - ball screws were replaced to resolve a jamming issue (this work was done in the summer).
The outrigger has been recalibrated and all limit switches and feedback signals tested. All ranges of motion were tested multiple times as well.

Tuesday, March 28, 2023, 12:02, Nadia Jorgenson, Service Bridge, Repair, Outrigger 1 Failure and Repair
|
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. |
|
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. |

Thursday, October 25, 2012, 13:58, maicodallavalle, Service Bridge, Maintenance, Orbit Drive
|
It was observed during the last time the Cyclotron service bridge was used the orbit drive chain had a lot of slack. The drive motor had to be shimmed
to tighten the slack in the chain. |

Friday, February 21, 2014, 11:05, Bevan Moss, Cyclotron, Standard Operation, Old Monitor Box Removed, New installed 7x
|
One of the beam spill monitor boxes was removed and placed into a lead coffin. The fields around the coffin prior to the monitor being placed in
were 145 uSv/hr just above the box and 33.5 uSv/hr inside of it. A swipe was taken inside the box at this time and a count of zero was found. The tray
for the monitor box was then placed into the coffin and the monitor removed from the cyclotrons. The field above the coffin with the monitor box was 1.0 |
 Friday, February 21, 2014, 15:58, Bevan Moss, Cyclotron, Standard Operation, Old Monitor Box Removed, New installed
|
During the electrical test the was no contact. To help investigate further the Montitor box was removed from the Cyclotron. It was found to have
zero counts. The issue is believed to have to do with the fit of the box but confirmation of the writing harness continuity needs to be completed. This
will continue on Monday. |

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: |

|
A new remote crane pendant was installed to replace the existing wired pendant on the B2 level of Remote Handling building (basement area - vault access).
Two remote pendants exist (spare). The previously used pendant will be kept, at least temporarily, as a backup if needed.
