On Monday June 8 the following work was performed by Isaac Earle and Keith Ng:
- EHDT beamline vented
- Band clamp and o-ring seal removed |
|
Wednesday, June 10, 2015, 14:57, Isaac Earle, 100KW Beam Dump, Development, BD Water System Leak Test
|
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 |

Friday, June 12, 2015, 10:16, Isaac Earle, 100KW Beam Dump, Development, Beam Dump Vac Seal Vent & Test
|
- Vacuum has been pumping steadily on the EHDT section since June 8, reaching 3.2E-8 Torr at 8am today (June 12)
- Leak check performed this morning by Anthony Ip: no leaks
- Vacuum vented and re-pumped, leak check repeated: no leaks |

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") |

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 |

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, 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. |

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 |
