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

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.

Entry  Wednesday, February 07, 2024, 12:04, Adam Newsome, Elevation Jack, Repair, Elevating system - brake master relay fuse issue 
It was observed when attempting lid up operation on 2024-02-06 that the brakes for each of the jacks were not operating correctly. It appeared that power
was not being applied so the brakes were stuck in the engaged state. This ultimately resulted in issues with the lid up operation. 
The issue was traced to relay A1 (the master brake power relay) not toggling as expected, despite the relevant control signals being present to
Entry  Thursday, February 08, 2024, 08:50, Adam Newsome, Elevation Jack, Maintenance, Elevating system - station 10 motor contactor issue 
It was observed during lid up operation on 2024-02-08, approximately halfway through raising the lid, that the motor contactor for station 10 located
within its small motor panel stopped functioning. The symptoms observed were: entire system stopped since station 10 lagged behind (approx. 150 counts
on counter), station 10 could not be jogged locally in either direction, the control signal to activate the motor was being sent to the contactor when

The cyclotron lid was raised starting ~10:30am on 2024-02-06 and finishing at ~3:30pm on 2024-02-08, under work permit C2024-02-06-4. 

Upon first attempt to raise the lid, issues were encountered. The system seemed to start as expected but quickly tripped, resulting in no appreciable
Entry  Wednesday, April 24, 2024, 14:26, Adam Newsome, Elevation Jack, Standard Operation, Lid up operation (second) - 2024 Elevation_System_Checklist_-_2024_-_Second_Lid_Up.pdf
Due to an issue with resonator latching, there was a need to raise the cyclotron lid a second time this shutdown.
The plan at first was to raise the lid by small increments (approximately 1mm at a time up to approximately 25mm) while RF group performed some
checks.

The cyclotron lid was raised starting ~11:45am on 2024-05-02 and  finishing at ~12:12pm under work permit C2024-05-02-5. 

The raising was stopped a few times up until approximately 5" elevation, for RF group to perform checks, and to inspect the tank seal.

Entry  Tuesday, March 05, 2013, 14:11, Travis Cave, Cyclotron, Standard Operation, Setup and the Installation of the HE 1 probe. 
Setup of the HE 1 probe is difficult has we have no mockup of it to properly setup cameras and equipment for it. This is problem for both extraction
and installation of the probe. Also with the setup some of the broken micro switch from the HE 1 was found on the HE 1 probe jig after the jig was deconned
and moved up the B2 level. Also for setup required camera adjustment to be made with the heavy contaminated probe being very close to the person setting

This morning during routine service bridge work in the Cyclotron tank, it was observed by Travis Cave that the cable tray for the Remote Handling service
bridge was catching on something on the top inside surface of the Cyclotron tank.  The cable tray was observed to visibly snag on this protrusion
and then bounce around.

This morning Don Jackson commented to Grant Minor that he believed the tank lid was still not raised high enough to safely operate the Remote Handling
bridge and trolleys, despite it having been raised 0.5" yesterday to the point of engaging the limit switches (see e-log from yesterday).  Don
said he believed this to be the case as a result of a visual inspection with binoculars from the outside of the tank, as well as from the views achievable

Today Grant Minor, Dan Wright, Arthur Leung, and Dan Louie checked the height difference between the tank lid upper travel limit switch and the tank
lid over travel limit switch at both stations 1 and 10.
In the attached photos, the upper travel limit is the lever on the right.  The over travel limit is the lever on the left.

In tank survey completed.  A few items of interest were found.  Ladders need to moved manually outboard to #5 resonators and the items noted

Entry  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
Entry  Monday, March 18, 2013, 15:12, Isaac Earle, Cyclotron, Maintenance, Cyclotron Magnet Face Gap Measurements 8x
Measurements of the cyclotron magnet face gap were taken on March 15, 2013 at two locations around the tank with the cyclotron lid in the fully raised
position (the lid had been raised until the upper limit switches caused the control system to stop travelling).  The purpose of the measurements is
to establish an independent means of verifying correct lid height before beginning in-tank remote handling activities at the start of a shutdown period.
