all shields, porthole covers and ladder out and copper blockers in. Some conmination was found on the pads of the ladders (about a 1000 count or so)
and was removed. |

More shields have been removed from the cyclotron only 16 remain. I was also noted that the lift trolley is making an odd noise and will be looked at
after the shutdown. |

|
One of the beam spill monitor boxes was removed and placed into a lead coffin. The fields around the coffin prior to the monitor being placed in
were 145 uSv/hr just above the box and 33.5 uSv/hr inside of it. A swipe was taken inside the box at this time and a count of zero was found. The tray
for the monitor box was then placed into the coffin and the monitor removed from the cyclotrons. The field above the coffin with the monitor box was 1.0 |

|
During the electrical test the was no contact. To help investigate further the Montitor box was removed from the Cyclotron. It was found to have
zero counts. The issue is believed to have to do with the fit of the box but confirmation of the writing harness continuity needs to be completed. This
will continue on Monday. |

Wednesday, January 29, 2014, 15:08, Bevan Moss, Cyclotron, Standard Operation, Shielding and Port Hole Covers
|
The Shielding and the Port Hole Covers have all been installed. No issues with the installation have caused any problems. This orbit, radial, and
vertical read back continues to be an issue. |

|
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. |

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 |

Friday, January 17, 2014, 07:53, Travis Cave, Trolleys serviced, Standard Operation, Trolley checks
|
All trolleys work electrically and control wise. One encoder was found non functioning on the upper resonator trolley for the vertical drive it was replaced,
we've no move replacements of those current type of encoders so a wholesale replacement of all the trolley's encoders will have to be done post shutdown.
Also the wiring for the outrigger is in need of replacement but will work for this shutdown it will also have to be replaced post shutdown as well. The |

This is a list of all the trolleys and other equipment witch were checked and serviced prior to work in the Cyclotron.
- Video Trolley cleaned and checked (no adjustments needed)
-Lift Trolley cleaned and checked (no adjustments needed) |

Thursday, April 11, 2013, 19:00, Grant Minor, Elevation Jack, Maintenance, Upper Bearing at Jack Station 9 + Fall Protection Upgrades
|
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) |

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 |

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. |

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 |
