|
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. |
Wednesday, November 26, 2014, 17:50, Isaac Earle, 100KW Beam Dump, Development, Installation of Lower Center Block (TSH0461) 
|
Painting and relabeling of the modified lower center block (TSH0461) was completed on Monday Nov 24. The
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 |

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 |

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 |

Wednesday, September 15, 2021, 15:10, Adam Newsome, T-Hall Crane, Maintenance, Hoist Broken Fault (actually: cable wrap issue)
|
A fault occurred which presented as "114. Main Hoist Cable Broken (3200PX)". This occurred when a SEG block was suspended approximately 1 m
off the ground.
Upon inspection, it was determined that the cable was in fact not broken, but wrapped around itself. There are no guides, and it is possible for |

Wednesday, May 06, 2015, 14:19, Isaac Earle, 100KW Beam Dump, Development, EHDT Beam Pipe Section Installed
|
- On May 4th the EHDT beam pipe section was installed by Mike Vogel of Beamlines Group
- A new Helicoflex seal was used (provided by Vacuum Group)
- 4" RH Clamp was installed by Isaac Earle. Clamp became stiff in early travel, was backed off, then fully tighetend down to stop-ring |

Monday, June 15, 2015, 17:08, Isaac Earle, 100KW Beam Dump, Development, E-Dump Shielding Installation
|
- 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") |

Tuesday, September 10, 2024, 12:52, Adam Newsome, T-Hall Crane, Standard Operation, Drive not ready faults observed on power-up
|
Upon powering on the crane today and attempting to use the main hoist, the following faults were present:
1. Main Hoist East Drum North Motor Drive Fault (700VFD)
2. Main Hoist West Drum South Motor Drive Fault (900VFD) |

|
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). |

Wednesday, November 19, 2014, 13:49, Isaac Earle, 100KW Beam Dump, Development, Decision on Modifications to Lower Center Block (TSH0225)
|
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 |

Tuesday, March 21, 2023, 10:47, Adam Newsome, Hot Cell 1, Repair, Circuit breaker replacement - telemanipulators
|
There was an issue with a 20 A circuit breaker used to control motor assist functions for the telemanipulators (specifically, the rightmost CB in the
panel for the right (East) manipulator set). This circuit breaker was moved to the panel for the left (West) manipulator set in the rightmost position,
and then subsequently replaced with a new one, which is functioning correctly. It is suspected that the former CB which was not working was calibrated |

Thursday, September 16, 2021, 09:37, Adam Newsome, T-Hall Crane, Maintenance, Bridge Encoder Homing
|
The bridge motion was slowed due to encoder homing issue. It is likely that the problem which occurred yesterday caused an velocity fault (mismatch between
encoder speed and commanded speed), which unlatches the homing status for the bridge motion axis.
When the bridge was in the southmost position (bumper pressed against wall), the position readback was: 0.353 m, encoder count = 5164003. |

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 |
