 Friday, February 06, 2015, 13:32, Isaac Earle, 100KW Beam Dump, Development, TEL5079 Hose Modification
|
When the EHDT shielding service stand shield plug was installed in January it was found that the Beam Dump Outlet Hose (TEL5079) was interfering with
the plug. The following remedial action was taken:
- Upper lead water blocks disconnected and upper lead shield removed w/ hose assemblies and upper half of water blocks attached |
Friday, March 20, 2015, 11:45, Isaac Earle, 100KW Beam Dump, Development, Lower Half of BD EHDT Shielding Installed 
|
The lower half of the beam dump EHDT shielding was installed yesterday by Plant Group. After installation of the service stand plug, the
position of the south and east faces of the plug were checked with the laser tracker w.r.t. EHAT MB4. The south face was within approximately 2mm
of nominal, and the east face was approximately 6mm east of nominal position. It was decided that this positioning was acceptable. The modified |

|
Thursday, May 07, 2015, 16:23, Isaac Earle, 100KW Beam Dump, Development, RH Clamp Installed with Used Seal
|
The remote handling 4" marman flange clamp was reinstalled today with a used seal. It is "Clamp B" as tested in Document-114623.
The purpose of installing the clamp now is to prepare for the upcoming remote handling test of the vacuum joint and one of the water blocks.
During installation it was found that it will be necessary to manipulate both the BD flange and the EHDT beam pipe flange to have the seal mated |
|
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 |

|
Monday, June 08, 2015, 15:15, Isaac Earle, 100KW Beam Dump, Development, Beam Dump Vacuum Leak
|
- On Thurdsay June 4th the EHDT beamline section was vented by Vacuum Group so that they could install a new pump
- After pumping down again a leak was found at the BD front flange seal around the top of the seal
- The RH clamp and Helicoflex seal were removed and an o-ring seal was installed with a band clamp |
|

|
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. |

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 |

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 |
