As there likely won't be an opportunity to properly document the design of the beam dump insert and cooled lead shielding in design notes, a list
of design reviews, released on Docushare is provided below. These provide a reasonable overview of the design process for each item. In addition
the attached PDF of scanned notes provides detailed information on the lead shielding design. Further notes, ANSYS documents, meeting minutes, concept |

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. |

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 |

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 |

Friday, May 15, 2015, 11:06, Isaac Earle, 100KW Beam Dump, Development, BD and Upper Pb Shield Water Hoses Replaced
|
The beam dump and upper lead shield flexible hose assemblies have been replaced with smaller diameter versions to allow for easier remote handling.
The new beam dump hoses are TEL5501 (Rev A) & TEL5502 (Rev A). The new upper lead hoses are TEL5503 (Rev B) and TEL5504 (Rev B). All
Swagelok joints were installed 1-1/4 turns past finger tight as per Swagelok instructions. The new Swagelok connections have not been leak tested |

A leak test was performed on the beam dump water system on June 9 in the afternoon.
- Pipe segments tested: The entire HAW system except for the expansion tank, air separator and HAW pump
- Test medium: air |

|
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 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

|
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 |

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). |

|
A spare pendant for the overhead crane was procured from COH. The pendant's functionality is the same as the original one's. The pendant was tested today
by Adam Newsome - all functions behave as expected.
Important - to change to the spare pendant in the case of failure of the original one, insert a battery into it, and transfer |

Tuesday, April 25, 2023, 12:28, Adam Newsome, T-Hall Crane, Standard Operation, ARIEL Target Hall Crane - Drives Fault
|
Today while operating the crane with load, the crane stopped moving. Upon investigating, all safety signals appeared to be OK. Fault messages regarding
drive faults for various VFDs were present, which seemed to stem from an ethernet adapter card fault (see attached photo). It is unknown how this occurred,
but suspected that it was due to a brief blip in network communications or the external drive power supply control signal. It is worth noting that the |
