|
All of the old brass air fittings on the Tool Trolley have now been swapped over to push-connect style fittings. As these are plastic fittings, it is
recommended to inspect them after ~5 years for degradation. |

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: |

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 |

All shadow shields which are remotely placed inside the cyclotron during shutdown were inspected by Adam Newsome and Chris Peterson on Jan. 13, 2021.
The inspection consisted of:
Verifying feet were damage-free, welds intact (note: only outer feet were checked due to the large amount of effort that would be involved |

Repair of Orbit Limit Switch Plastic Belt
During the fall of 2011, Remote Handling discovered that a plastic toothed belt had stripped in the Cyclotron
Bridge orbit limit switch mechanism. This toothed belt is supposed to wrap around the stationary outer race/chassis of the center-post bearing on |

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. |

|
The hydraulic cylinder on the West side of the service bridge (used to raise the bridge for insertion into the Cyclotron) failed this morning, leaking
oil in the vault tunnel. Most likely this was due to a failed seal or gasket.
Maico Dalla Valle has removed both the East and West cylinders for refurbishment and is pursuing repair kits from Hyseco. |

On Monday February 4TH the Service Bridge was being lifted into the Cyclotron with the Carrier. It was noticed that one of the two Hydraulic
Jacks was leaking. All work stopped and the Service Bridge and Carrier were moved to the Remote Handling B2 level for repair. The Service Bridge and Carrier
were separated and the Hydraulic Jacks were inspected. It was noticed that both Hydraulic Jacks were leaking. Two overhaul kits were ordered. Two other |
