Braze Test update and plan forward Test Mandrel has been machined for the braze wire groove and the OD reduced (~0.4mm diameter) to eliminate tubing distortions. QC department has measured the 4 Quarter Jaw IDs and the Test Mandrel and determined modifications to the Jaws are necessary. Jaws are being modified by shop. Promise completion date 12/12/06 Klystron Manufacturing Braze Shop will then perform Jaw brazing on 200mm long Assy. Promise completion date 12/19/06 Assembly will then be sectioned for braze joint inspection. LARP LHC PHASE II COLL RC1 TESTS - S. Lundgren 11 Dec 2006 No 6 /17

More Braze development tests planned A second 200mm long Copper mandrel will be fabricated for more Jaw braze technique development and winding practice before the full size Heater Test Mandrel is attempted. Molybdenum to copper braze tests are in the planning stages. LARP LHC PHASE II COLL RC1 TESTS - S. Lundgren 11 Dec 2006 No 8 /17

RC1 near term plans Bending 10mm sq. OD/ 7mm sq. ID copper samples into design configurations to check for distortions (internal and external) Samples are being fabricated from 11mm sq. CDA101 conductor Interested in knowing how much the tube deforms inward (relative to Mandrel OD) as a result of winding If deformation is unacceptable may need to bulge it back out by over-pressurizing the tube after brazing Still on the list: Twist a few samples to failure for a measure of the margin of safety and to determine actual torque required Starting detail work on: Collimator End Supports and Bellows Assy Prototype “Rotator” design for proof-of-concept testing U-Joint for initial deflection tests Fabrication of appropriate CERN hardware Drawing Trees and Lists for this are in work LARP LHC PHASE II COLL RC1 TESTS - S.

RC1 longer term plans Beginning to think about a Dummy Collimator for use in beam tests in 2007/2008 before final prototype is delivered for damage tests: no rotation no cooling one jaw 2 jaw steppers For impedence tests: 2 Jaws 4 steppers Image Current Plate with RF springs no water cooling ??? What tests are really possible in 2007? Should we be preparing this hardware? LARP LHC PHASE II COLL RC1 TESTS - S. Lundgren 11 Dec 2006 No 12 /17

Image Current Plate and Jaw Solid Model The next few slides show the Image Current Plate and RF Contact options in the Solid Edge Prototype Model recently emailed to Ralph Assmann. Try to open the Solid Edge model. Review the designs Your comments will be greatly appreciated Advise us as to which option, if any, best meets the project goals Incompatible software interface? How can we provide a better transfer for this and future more complicated models? LARP LHC PHASE II COLL RC1 TESTS - S. Lundgren 11 Dec 2006 No 13 /17
