 Thursday, November 28, 2024, 09:04, Adam Newsome, Hot Cell 1, Repair, Hot Cell turntables not rotating, access hatch not moving
|
It was reported that the hot cell turntables would not rotate and the access hatch could not be operated. The turntables' elevation motion was working
normally, and other cell functions were working.
Upon investigation, after going online with the PLC and checking the interlocks for the turntable, it was determined that motion was being prevented |
Friday, November 29, 2024, 15:23, Adam Newsome, Hot Cell 1, Maintenance, 1000 kg crane: y axis position display not functioning 
|
After a recent power cycle, the y-axis referencing was lost for the 1000 kg crane. The position readout was also incorrect, somewhere on the order of
> 30,000 mm. On 2024-11-29, A. Newsome re-referenced the y-axis. The position readout correctly reset to zero, and both +y and -y motion is functioning
correctly, but the y-axis position readout on the HMI constantly displays 0 and does not change. To be investigated. |

|
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 horizontal VCR joint
on the DRIVE BEAM CONE (ATA3674) could be undone with the manipulator and standard wrenches, it is advisable to use 'semi-closed' wrenches on the nut to |

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. |

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.

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. |

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 |

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. |

|
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 |

I received a call today from Jim Adamson at Kaltech regarding modifications to shielding block TSH0225.
They had finished removing 19mm from the bottom of the block, as well as removing 10mm of material from the side plates (TSH0246). He was
wondering whether it was also necessary to remove material from the back plate (TSH0253) and weld the back plate to the 6" plate (TSH0252). I |

Testing was performed on the ceramic water breaks to be used on the beam dump water hose assemblies. The ceramic breaks are a custom MDC product
with the following description: 3kV ceramic break, 1" OD tube 0.083" wall thickness, 2" length, 304SS tube stub each end, 250psi water
rating (see TRIUMF PO# TR199315). |

height of the modified block was measured at the four corners using a tape measure and found to be approximately 533mm at all corners.
The block was lowered to the E-Hall and aligned on Tuesday Nov 25. No cantilever lift was required because the catwalk above the hatch had |

On November 28th the lower lead shield was installed with 3/8" shimming at the front end, and 11/32" shimming at the rear end. The south
and east faces were aligned as flush as possible with the lower center block. The beam dump insert was then placed on the rails in the lower lead
shield. |
