|
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. |

|
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 |

Tuesday, December 16, 2014, 16:36, Isaac Earle, 100KW Beam Dump, Development, Upper Pb Shield and Water Hoses Installed
|
The upper lead shield was installed this morning. Also the water hoses for lower lead shield, beam dump, and upper lead shield were all installed.
See attached photos and hose installation information PDF. |

Friday, December 05, 2014, 10:43, Isaac Earle, 100KW Beam Dump, Development, Lower Lead Shield Drain Line Installed
|
A 1/8" SS tube was routed from the Swagelok fitting on the front of the lower lead shield to the service stand water catch tray as shown in the
attached photos.
The tube was routed to fit in the cut-out and chamfered corner gaps of block TSH0387 in the de-rated EHDT shielding assembly TSH0293. |

Wednesday, December 03, 2014, 10:45, Isaac Earle, 100KW Beam Dump, Development, BD Signals Traced from Service Stand to Junction Box
|
On Dec 2 the cables from the BD service stand area to the junction box were traced to establish which sensors correspond to which cable number in the
junction box.

Wednesday, December 03, 2014, 10:36, Isaac Earle, 100KW Beam Dump, Development, Upper half of BD water blocks installed; Bypass loops installed
|
On December 2 the upper half of the RH water blocks were installed (4 total) using a 0.030" thick 6061-T6 Al shim torqued to 60ft*lbs as was tested
in Document-114260.
Bypass loops for testing the cooling system piping were installed as shown in the attached photo. |

Wednesday, December 03, 2014, 10:16, Isaac Earle, 100KW Beam Dump, Development, Installation of Lower Lead Block and Beam Dump Insert
|
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 |

Friday, November 21, 2014, 13:37, Isaac Earle, 100KW Beam Dump, Development, Destructive Testing of 1" MDC Ceramic Breaks
|
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 |
