6. 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.

7. Mandrel and Coil ready for braze wire groove and clean-up machining
LARP LHC PHASE II COLL RC1 TESTS - S. Lundgren 11 Dec No 7 /17

8. 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.

9. Single Jaw Thermal Test Hardware Progress
Clean Tent infrastructure upgrades nearing completion.
The room is filling up with equipment
Molybdenum Shaft completed and in house on 11/28/2006
Jaw 1/4 sections qty 22 released to vendor (includes 2 spares and 4 for additional Short Mandrel Tests)
Late January anticipated
Improved/Revised Mandrel design released to vendor for fabrication
Mid January date promised

11. 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

12. 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?

13. 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 ed 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?
