Friday, December 19, 2014, 14:05, Isaac Earle, 100KW Beam Dump, Development, Beam Dump & Lead Shielding Design Documentation
|
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 |

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 |

|
A 4" Remote Handling Marman Flange Clamp was delivered to Doug Preddy today to be used to clamp the EHDT beam pipe section to the beam dump
during beam pipe installation.
The clamp is one of the two manufactured in 2014, Identified with marker "B" |
|
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 |
|
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 |

|
- 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 |
