Lid down operations for 2019/2020 shutdown went ahead as planned on March 10th 2020 with Dan Louie and Arthur Leung absent due to a conference. Please
see attached file for station counter numbers. Station two right side Highfield gear box was making intermittent growling from outboard bearing, this station
is next on scheduled maintenance and will be inspected post removal next shutdown. Station 3 has spare jack set 13 in place, using Operations thermal camera |

Friday, March 15, 2013, 15:18, Grant Minor, Cyclotron, Standard Operation, Lid Down Successful - Mechanical Counter Readings
|
Prior to the lid-down operation today, the Cyclotron was lowered by 0.75" and then raised again to confirm that the upper limit switches were working.
Dan Louie confirmed this from the control racks.
Maico and Grant walked around the perimeter of the cyclotron to inspect each station and ensure that there were no interferences, e.g. dial indicator |

|
Lid down Started at 12:15, station and count numbers. Lid went down with out incident as station 1 and 7 show the counters will need replacing. We are
going to change counters before the end of this shutdown to ensure proper orientation in case of emergency lid up scenario.
Start 12:15 |

|
The newly developed Ladder Handling Tool (TRH1401), which is used to move the maintenance ladders from the #5 resonator area closer to the centre post,
was tested inside the cyclotron tank to perform the actual operation. This is a task that was historically performed by operators, resulting in dose received
(typically 0.1 - 0.3 mSv for two people, twice per annual shutdown). This tool completely eliminates the need for people to receive this dose - only a |

|
The LE1/LE2 Probe Frame was mounted on the Upper Resonator Trolley in the mockup with the intention of confirming functionality and making some updates
to the probe installation/removal procedure document.

|
A simulated removal of the LE2 Probe from the Cyclotron tank was performed by the RH and Probes group using the
service bridge, upper resonator trolley, LE probe attachment, and the (soon to be) attached LE Probe removal
procedure on 2017-02-23. |

|
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.

Annual jack maintenance : Jack 10b upon inspection it was found that the output shaft seal on 10b was in need of replacement. In past years RH personal
had to remove a LoveJoy coupling which required cutting of the coupler due to galling and possible interference tolerances being out. We sourced sample
split seals from Motion Canada that can be installed with out coupling removal we will install and monitor to determine the effectiveness and the possibility |

|
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 |

|
Maico Dalla Valle and Grant Minor, supported by Dan Louie and Arthur Leung, entered the Cyclotron Vault on January 15th, 2014 to check the indexing of
the jacking stations. 520MeV work permit 2014-01-15-4 was filled out for this work.
Yoke gaps at all stations were found to be within .005" to .010" of the .25" shim stock, and all mechanical counters were found |

Monday, February 04, 2013, 13:52, Grant Minor, Service Bridge, Repair, Hydraulic cylinder failure on service bridge 6x
|
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. |
