 Wednesday, February 06, 2013, 18:07, Grant Minor, Elevation Jack, Maintenance, Lid-down yoke gap measurements from 1994 
|
Attached is a scan of a handwritten record from 1994 showing yoke-to-upper-structure gap measurements from 1994, both L and R sides, with tank under
vacuum and vented.
The measurements appear to be made with a 0.25" shim and 0.01" pieces of shim stock as they are only in increments of 10 thou. |

Friday, March 08, 2013, 18:42, Grant Minor, Cyclotron, Repair, Tank lid not at upper limit and resulting effects
|
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 |

Thursday, March 14, 2013, 19:57, Grant Minor, Cyclotron, Repair, Tank lid upper / over travel limit check
|
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. |

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 |

Tuesday, March 19, 2013, 19:17, Grant Minor, Elevation Jack, Standard Operation, Re-indexing of all jack station "zero" yoke elevations
|
The dimension between the yokes and the Cyclotron upper structure primary beams was set to .25" nominal at all jack stations today.
At each station:
The jacks were jogged manually upwards until the yokes hard-stopped on a piece of .25" nominal shim stock (see attached reference |

|
There was a brief access period to the Cyclotron vault during April 9 to 12, 2013 due to other Cyclotron issues.
This time was utilized to perform the following Elevating System tasks:
- Drilling of 2 (two) holes for concrete anchors (DBI Sala Product 2100085) for self-retracting lifelines (see TRIUMF purchase order TR197399) |

Monday, January 20, 2014, 12:00, Grant Minor, Elevation Jack, Standard Operation, Indexing Check of Cyclotron Jack Stations
|
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 |

|
Yesterday Grant Minor (me), Maico Dalla Valle, Dan Louie, and Arthur Leung worked with Operations to perform the Cyclotron Lid-Up task for the 2014 winter
maintenance.
Work Permit 2014-01-22-2 was issued for this job. |

|
The Cyclotron Lid Down was successfully completed today on Work Permit C2014-03-03-6.
The system only tripped twice on the way down. Both trips were at Station 9, at the following Master Syncro readings: 43194, 39198.
Oil was observed on the Jack #1 platform, but it was determined that it was coming from the crane when it's parked in the beam-on position, and |

Wednesday, July 02, 2014, 16:46, Grant Minor, Elevation Jack, Standard Operation, Cyclotron Lid-Up Report for 27 June 2014
|
The cyclotron lid was raised on June 27th, 2014. Start time was 1:05pm end time was 2:17pm (good!) Dan McDonald collected and recorded numbers
from the mechanical counters for the lid up sequence, I am entering the data into the e-Log on his behalf.
Below are the mechanical counter values from the start and finish of the lid-up job: |

5 x TRH1217 Upper Bearing Service Platform assemblies were installed between January 6th and January 13th at Stations 8, 10, 3, 4, and 5 (see attached
photos).
The assembly went very smoothly. Dan McDonald and Maico Dalla Valle worked together to install the platforms and wore harnesses and lanyards |

Lid was raised today (2nd time during 2015 shutdown) for additional inflector work.
Dan and Maico report that the lid went up smoothly and no jogs were required. The operation took about 30 minutes.

Thursday, September 17, 2015, 18:38, Grant Minor, Elevation Jack, Maintenance, Station 9 Jack Worm Gear Inspection - unusual wear markings 16Sept2015 8x
|
Unusual wear markings were observed on the Station 9 jack (not sure if L or R jack?) during a visual inspection.
The grease looked to be in good condition and no sign of chips or contamination was found in the grease, so it is possible that the wear markings
are older. |

The installation of the upper bearing fall protection equipment was completed last week by Dan and Maico.
- Full safety platform assemblies (ref. TRH1217) were installed on stations 1, 6, 7, 11, 12
- Short safety platform assemblies (ref. TRH1248) were installed on stations 2 and 8 to avoid interference with the lights |
