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 |
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. |
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 |
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, May 07, 2025, 13:50, Isaac Earle, Hot Cell 1, Development, Prototype testing of APTW beam dump module water connections  
|
Test jig ATA6060 was used to evaluate the 1" VCR connections on the APTW Beam Dump Module (ATA5900). The test jig accurately mimics the space
constraints on the real module. This testing was prescribed as an action item from the design review for the module due to concerns that very high
force would be required to make the connections. The test jig was installed on the east shelf in the hot cell. |
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 |
Thursday, October 17, 2024, 11:34, Albert Kong, Hot Cell 1, Development, Tarping completed on hot cell roof  
|
Two tarps were installed above the hot cell roof to protect against concrete dust while testing in the hot cell.
Zip ties were used to hook the tarp onto tubing brackets on the back wall. |
Tuesday, November 19, 2024, 15:38, Albert Kong, Hot Cell 1, Standard Operation, APTW Front End Moved into Hot Cell 23x
|
The APTW front end was moved into the hot cell, on the lift table, following procedures outlined in Document-244862.
The mock-up frame was transferred from the east turntable to the west turntable above the front end. The east turntable is covered with the aluminum
plate. During covering we accidentally broke the o-ring for the turntable plate flange. The new o-ring seal should be made ~1" longer in circumference |

|
Removal and replacement testing of the stainless VCR lines extending from the HVFT to the piston modules and FE plate is documented in this ELOG.
Exchange of the FE plate water connector lines is documented in a ELOG #79. Exchange of VCR gaskets in the permanent joints is given in ELOG #83.

Wednesday, January 15, 2025, 12:57, Albert Kong, Hot Cell 1, Development, APTW Front End HTV Water Connector Exchange Testing    
|
The four water connections on the front end plate of the APTW that will connect to the HTV were tested for replacement with the manipulators:
The pin on these connectors were fairly easy to remove and replace with the old pin detent tool.
The pin detent tool could
also be used to manipulate the water lines while protecting the sealing face.
The horizontal VCR joint on the DRIVE BEAM CONE (ATA3674) could |
Wednesday, January 15, 2025, 13:09, Albert Kong, Hot Cell 1, Repair, West turntable festooning pillar and cable damage
|
Some issues were encountered with the turntable controls on the west hot cell, as a result the festooning post for the turntable was damaged. While the
post was out of commission, the turntable was operated without actively monitoring the top of the hot cell and some cables ended up catching on the limit
sensors, causing some slight fraying. The cables were duct-taped to prevent shorting for now but should be inspected and replaced accordingly in the future. |
Wednesday, January 15, 2025, 13:23, Albert Kong, Hot Cell 1, Development, APTW Front End Power Busbars Stabuli Connector Exchange
|
We successfully performed a removal and replacement of a power busbar stabuli connector on the front end plate where the HTV connects to:
The middle-lower connector was tested as the others are more straightforward to work with.
It may be a good idea to use
a 3D printed jig to wedge into the connectors without damaging the flexures/pins.
A longer hex bit on the hot cell torque tool would greatly |
Wednesday, January 15, 2025, 13:52, Albert Kong, Hot Cell 1, Development, APTW Front End VCR Gasket Selection
|
Today RH (CF and AK) agreed upon using the following style of gaskets for the ARIEL front ends:
All metal rings to be used to avoid plastic retaining rings deteriorating due to radiation and leaving bits stuck in the nuts
Parker style (4 VGR-SS and 8 VGR-SS) gaskets for all VCR joints, except
For the piston module and hanging water line VCR joints (found |

Feb 13:
The 'hanging' VCR joint on the driver side was successfully exchanged by hand:
The adjacent HV shielding had to be removed to do so
Access to the screws on the shielding is limited so likely the use |

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.

Thursday, February 13, 2020, 08:51, Adam Newsome, T-Hall Crane, Standard Operation, Remote mode door limit switch bypass
|
The non-existent safety limit switch for the target hall door which prevents remote motion has been bypassed in the crane PLC control panel to allow
for remote operation of the crane. This will be un-bypassed when a switch is installed. Specifically, a jumper was placed from terminal 18001 to 20121
and 20141 which will enable the hall lock safety relays 2012SR and 2014SR. The crane is currently operational in both local and remote mode. |
