Attached is a scan of a handwritten record from 1994 showing yoke-to-upper-structure gap measurements from 1994, both L and R sides, with tank under
vacuum and vented.
The measurements appear to be made with a 0.25" shim and 0.01" pieces of shim stock as they are only in increments of 10 thou. |

|
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. |

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

Friday, February 17, 2012, 15:07, Don Jackson, Trolley, Repair, Video Trolley Failed in Cyclotron Tank
|
All control to the video trolley was lost during remote photographing of components in the cyclotron. The control system and cameras on the trolley were
still operational leading to the suspicion that a power cable was broken either on the trolley or the bridge festooning. Two trips into the tank were
made to evaluate the problem and attempt to push the trolley out of the tank. Pushing the trolley only managed to move the trolley a few feet before |

|
Today Remote Handling staff (Maico Dalla Valle, Travis Cave) used the Remote Handling 2C probe removal trolley to remove the probe assembly from inside
the Cyclotron. This is a regular yearly MRO task that is done every shutdown.
This task involves lining up the 2C trolley on the service bridge with the 2C probe assembly remotely with cameras, using a set of alignment markings |
