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, 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 |

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 |
|
Monday, December 22, 2014, 14:21, Isaac Earle, 100KW Beam Dump, Development, Water System Leak Checked
|
This morning Bill Richert pressurized the beam dump water cooling system with 30psi air and held for 2 hours. He reported no change in pressure
which indicates the flexible hose connections installed last week are leak tight. |

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 |

|
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. |

|
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 |

|
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 |
