Monday, March 21, 2022, 13:14, Adam Newsome, Trolley, Repair, Video Trolley Mk 1 - Radial Limit Switch Replacement
|
An issue was observed in which radial motion on the Video Trolley Mk 1 did not respond to commands. After troubleshooting, it was determined that this
was due to the "OP LIMIT" interlock - the "OP LIMIT" pushbutton on the console was illuminated in red, and needed to be continuously
held down in order to operate the radial in/out motion buttons. |

Tuesday, February 08, 2022, 11:39, Adam Newsome, Cyclotron, Development, Radiation Survey - sampling rate error
|
When attempting to perform the radiation survey, the program displayed an error at startup stating that the software was not able to keep up with the
incoming hardware samples, and suggested to increase sampling rate or buffer size. The default sampling rate of 500 ms was not used - rather, 100 ms was
used. No issues were observed with this rate. As far as I am aware, this issue had not occurred in the past, and the cause is unknown. |

Tuesday, August 31, 2021, 14:28, Adam Newsome, Trolleys serviced, Development, Upper Resonator Trolley - Finger Cylinders Replaced 
|
The two support fingers on the upper resonator trolley were bent due to excessive loading during cylinder toggling.
Fingers were bent back into position such that they are vertical when the cylinder is retracted.
The cylinders used to actuate these fingers were replaced (one was leaking) - replacement allowed for the opportunity for upgrade. The following |

|
The following items from Phase 1 of 2 of Bridge Lift Mechanism Refurbishment (O504) are complete:
Replacement of pneumatic tubing
Replacement of hydraulic cylinders for lifting, and procurement of spare
The
newly refurbished system has been tested by Dan McDonald (June 16, 2021) and verified as functioning. |

Tuesday, April 20, 2021, 15:02, Adam Newsome, Carrier, Development, Emergency Trolley Rescue Winch: Installed and Tested
|
An emergency trolley rescue winch (TRH1527) was developed for the purposes of retrieving trolleys from the cyclotron tank whose radial drive have failed.
This winch was tested today on the carrier in mockup setting with success by Adam Newsome, Dan McDonald, and Travis Cave. The
following is a summary of the test: |

Friday, February 26, 2021, 13:00, Adam Newsome, Trolleys serviced, Maintenance, Lower Resonator Trolley - Radial Drive Failure Issue
|
On Feb. 24 while practising a training exercise, the lower resonator trolley unexpectedly experienced a radial drive failure. The trolley did not move
in either radial direction (this occurred after approx. 5 minutes in the tank, near the centre post, with FTRF jig installed). The trolley was retrieved
from the tank manually for investigation. Upon retrieval and testing on the mockup, the radial drive began to work again. |

Friday, February 26, 2021, 08:29, Adam Newsome, Trolleys serviced, Maintenance, First Turn Radial Flag (FTRF) Jig - Pneumatic Upgrade
|
Old fittings and broken pneumatic tubing on the FTRF jig have been replaced with new push-connect fittings and polyurethane tubing. The jig was previously
not in a functioning state due to damaged tubing. A pneumatic diagram was created in the process of the upgrade. The tubing will be cleaned up within the
next few days and the jig tested. |

|
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 |

|
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 |

|
A new remote crane pendant was installed to replace the existing wired pendant on the B2 level of Remote Handling building (basement area - vault access).
Two remote pendants exist (spare). The previously used pendant will be kept, at least temporarily, as a backup if needed.

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 |
