 Tuesday, November 19, 2019, 10:31, Adam Newsome, T-Hall Crane, Repair, 900VFD Encoder Board Replacement 
|
An issue arose in which the ARIEL crane hoist could not be moved. It was determined that the East and West drums were out of synchronization (by more than
0.2 m, which the limit) and the encoder board inside the 900VFD had failed.

|
Background: On 2019-06-25 a Pri VelFdbk Loss fault was discovered on the Main Hoist East Drum South Motor of the ARIEL Target Hall Crane. The crane was
used previously on 2018-08-22 without incident. The main hoist of the crane was unavailable until the Hugo Lapointe (Automation Technician) from the crane
manufacturer (REEL-COH) replaced the Allen-Bradley 20-750-ENC-1 Incremental Encoder board in the 800VFD with a new one, and replaced the Motrona cross |

Wednesday, March 13, 2019, 16:14, Isaac Earle, 100KW Beam Dump, Development, Testing EHD water leak detectors 9x
|
The following work was completed today on the EHD water leak sensors:
Mike Vogel installed a 1/4" copper tube which leads from the east side of the EHDT shielding down to the catch tray below the water
blocks. This can be used for future testing of the in-tray sensors without removing the shield blocks. It may also be possible to test the |

Wednesday, June 28, 2017, 17:37, Isaac Earle, BL4N, Development, BL4N 35-deg bender "No. 1" installed on magnet stand
|
BL4N 35-deg bender magnet "No. 1" has been installed onto the magnet stand with "stand leg" configuration in the Proton Hall
Extension loading bay area. The magnet fit as expected, and with the support legs resting on the ball transfers the magnet position could be easily
adjusted by turning one of the adjuster leg fasteners (with the others loose). After experimenting with position adjustment, the fasteners were torqued |

Monday, June 05, 2017, 16:16, Isaac Earle, BL4N, Development, BL4N 35-deg bender stand assembly complete 14x
|
Assembly of two complete bender stands was completed on Friday June 2nd
as well as installation of new hardware on the dipole magnets for support, adjustment, and seismic restraint. All parts were installed according
to drawing TBP1804. |

Thursday, June 01, 2017, 15:25, Isaac Earle, BL4N, Development, BL4N 35-deg bender adjustment blocks modified to fit magnet
|
Adjustment blocks were installed on the second dipole bender today (labeled "No. 03" "C15-III-57/15"). The mounting holes on
the magnet were not aligned properly, so modification was required for two of the blocks. The counterbored holes on TBP1809 were slotted 0.10"
vertically, and on TBP1808, 0.06" horizontal slotting was required. A stress analysis was performed to confirm that the blocks are still strong |

Tuesday, May 16, 2017, 17:30, Jason Kapalka, T-Hall Crane, Development, ARIEL Target Hall Overhead Crane Measurements
|
On May 5, 2017 the Beamlines and Remote Handling groups recorded distances in the ARIEL Target Hall from the Target Pit floor and B1 Target Hall floor elevations
up to the overhead crane girders and main hoist rotation plate using a laser measurement device (see attached file).
On May 19, 2017, the Beamlines
Group measured the B1 and Target Pit floor elevations relative to the Cyclotron centre (see attached file). |

Tuesday, May 02, 2017, 16:52, Isaac Earle, BL4N, Development, BL4N 35-deg bender stand hardened parts tested
|
Hardness testing was performed on 1 sample each of parts TBP1822 and TBP1823 (part of the 35-deg magnet stand assembly TBP1804), They were
found to be 60-60.5 Rc and 60-61 Rc respectively which is within spec. The alloy used to fabricate these parts was AISI #8620. The testing was performed
by Precision Heat Treat in Surrey who also performed the heat treatment at an earlier date. |

|
On April 18, 2017, an investigation was initiated to determine the cause of the ARIEL Target Hall overhead crane faults that occurred while attempting to
perform remote lifting operations in Test Mode on a 8.6 tonne SEG block (see E-Log #30). Hugo Lapointe (Automation Technician, REEL-COH) requested pictures
of the HIM (Human Interface Module) displays, located inside the electrical panels in the crane control room, immediately after a fault to assist with |

|
On March 29, 2017, a 9 tonne load was transferred in the ARIEL Target Hall with the overhead crane (TRIUMF crane #44). On April 3, 2017, several drops of
green oil were observed on the floor and hookblock directly beneath the single equalizing sheave. The Remote Handling department millwrights were notified
and an inspection of the crane using a man-lift was performed to verify the source of the oil leak. Upon inspection, it was confirmed that the green oil |

On March 29, 2017, a 9 tonne steel shield block was transferred from the ARIEL Target Pit and placed into a
wood container on the Target Hall B1 level with the overhead crane main hoist in Local Mode without incident.
Afterwards, the overhead crane was switched into Test Mode (which is the same as Remote Mode but without the

Thursday, April 07, 2016, 11:25, Isaac Earle, 100KW Beam Dump, Development, Result of VCR Gasket Corrosion Test
|
In August 2014 gasket corrosion tests were prepared by placing a 1" Swagelok VCR gasket in a 500mL beaker with de-ionized water and a 1"x3/4"x1/8"
piece of 6061 aluminum. Tests were prepared for a silver plated 316L SS gasket (Swagelok PN: SS-16-VCR-2), a silver plated nickel gasket (PN: NI-16-VCR-2),
and a TRIUMF made 0.060" thick 6061 Al gasket. The top of the beakers were sealed, and they were left to sit until March 2016. |

Monday, January 25, 2016, 13:20, Allon Messenberg, T-Hall Crane, Maintenance, Possible oil leak
|
Two small (approx. 5 cm across) puddles of green fluid were discovered on the floor, directly below the crane trolley. The hook block was lowered
and inspected. No fluid found on hook block.
The plant group (Neil Wong) was notified and asked to schedule an inspection when the maintenance crew is on site to inspect the ISAC target hall |

Tuesday, November 03, 2015, 13:15, Isaac Earle, 100KW Beam Dump, Development, Initial tests of beam dump water system controls
|
During the maintenance period today the E-Hall tunnel was accessed to begin controls tests on the beam dump water system and initial fill of the system.
This work was done by Bill Richert and Dave Morris while I observed. Before work began I verified that pressure relief valves were installed
as per the P&ID (TEL5104 Rev A) - they have been installed but the exhaust ports from the valves have not yet been routed to the active drain. They |

Wednesday, June 24, 2015, 15:19, Isaac Earle, 100KW Beam Dump, Development, Remainder of BD Shielding Installed
|
The location of the already installed blocks including the TSH0392 protruding lift bails were remeasured, and it was found that modification of the Standard
Lock-Block Flat Top block was not required. A Standard Lock-Block Flat Top block was installed in the place of TSH0487 in drawing TSH0372, and the
remainder of the blocks on top were installed. It was a tight fit for the lower two Half Height Lock-Blocks, but future removal of the BD shielding |

- The hoist rings were removed from the upper lead shield
- Two standard lock-blocks were installed over the E-Linac beam dump according to TSH0372
- 5/8" of shims were required on the north end of both blocks to make them level. Aluminum shims were used (1/2" + 1/8") |
