Station 11-12 where swapped for station 13-14 during 2018-2019 shutdown. Once lock out and motor disconnect was complete we commenced removal of spares
and installation of original equipment. Station 13 was swapped in for station 3 and the upper bearing was serviced. In addition to regular maintenance
we built and installed a cover for the void in between station 10-11, this void in shielding measured approx 2'x4'. RH borrowed a demo Milwaukee 1' cordless |

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 |

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 |

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. |
