Tuesday, February 21, 2017, 13:40, Isaac Earle, Cyclotron, Standard Operation, HE2 Probe Returned to Cyclotron
|
The HE2 probe was reinstalled in the cyclotron this morning following the procedure in Document #126165. An orbital bridge position of 247.35°
was used (same as for the removal on Feb 9th). The installation went smoothly. |
|
Thursday, February 09, 2017, 15:21, Isaac Earle, Cyclotron, Standard Operation, HE2 Probe Removed
|
The HE2 probe was removed from the cyclotron today following the
procedure in Document #126165. An orbital bridge position of 247.35° provided better alignment than 247.2
from the procedure. The probe signal head was intentionally left in the "up" position by Diagnostics Group which did not cause any issues |

Thursday, January 25, 2018, 17:16, Isaac Earle, Cyclotron, Standard Operation, HE1 probe removed
|
The HE1 probe was removed from the cyclotron today using the procedure in Document 126165. The reason for removal is so that Probes Groups
can attempt to repair a problem with stuck probe head drive. Due the failure, the probe head was almost at the inboard travel limit (towards cyclotron
center post) at the time of removal. Additional cut-outs were added to the HE probe frame to accommodate the probe head and ribbon cable wheel which were |

Wednesday, January 31, 2018, 11:20, Isaac Earle, Cyclotron, Standard Operation, HE1 probe reinstalled
|
HE1 probe was reinstalled in the cyclotron this morning as per the procedure in Document 126165. Hardware for the probe head motion had been
repaired/replaced by Probes Group, so the probe head could be put in the fully retracted position. The job went smoothly and nothing unusual was
encountered. |

Tuesday, February 16, 2016, 16:32, Isaac Earle, Cyclotron, Standard Operation, HE1 Probe Removed from Cyclotron
|
The HE1 Probe was removed from the cyclotron this morning following the procedure in Document-126165 (currently in draft status, to be released after
the probe has been reinstalled). The procedure took approximately 2 hours from when the trolley was put into the tank until when it was removed from
the tank with the probe. The procedure took from 8am - noon including putting the bridge into the cyclotron, and removing the probe from the trolley |

Friday, February 19, 2016, 10:17, Isaac Earle, Cyclotron, Standard Operation, HE1 Probe Installed in Cyclotron
|
The HE1 Probe was reinstalled into the cyclotron this morning following Section 3.2 in Document-126165 (to be reviewed and released after camera
view screen captures added). The procedure took approximately 1 hour from when the trolley was moved into the cyclotron tank until when it was removed.
Camera view screenshots were captured throughout the procedure and the probe head was inspected with the left outrigger camera after installation |

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. |

Tuesday, November 14, 2023, 12:13, Nadia Jorgenson, Service Bridge, Repair, First Festooning Car "H" channel replacement
|
Damaged "H" channel removed from the first festooning car, and spare channel was put in place.
Note: it seems like the aluminum channel is not strong enough for the forces its being put under, and is resulting in deformations (See picture
"Festooning car H channel deformation"). We suspect this has happened in the past, notches were cut out where the deformation likely occurred |

Tuesday, May 10, 2022, 11:26, Nadia Jorgenson, Cyclotron, Repair, Festooning rail rope and pulley system re-routed
|
The rope and pulley system that is used to raise the festooning rail across the vault shield door has been re-routed. It now makes use of all three pulleys
and is easier to raise and lower without interference. |

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: |

Sunday, April 05, 2020, 13:24, Dan McDonald, Elevation Jack, Maintenance, Elevating system station swap 2019-2020
|
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 |
