Wrap Up for Discussion
The need for a 450 GeV beam test area on thermal shock waves for the LHC is well established and accepted at the technical level.
We propose the WANF area for setting up a facility for testing close-beam devices with beam-induced thermal shock waves, prior to installation into sensitive accelerator environments.
This safe test bed will address all needs for the nominal/upgraded LHC : beam tests on collimators, absorbers, cables, SC magnet modules, instrumentation, windows … Radiation and safety aspects have been considered: strong support to move into WANF instead of irradiating a new tunnel area (e.g. TT61)!
Cost: 3.3 MCHF
(TL, base facility)
+
0.5 MCHF
(clean-up WANF)
+
0.6 MCHF
(upgrade)
Our goal was
2.0 – 2.5 MCHF
. No cheaper solution found! Some cost should not be paid by us (WANF clean-up)!? Possibilities to get additional budget?
Reminder budget phase II collimation total :
5.1 MCHF
(CERN) +
0.7 MCHF
(EU).
This must cover the collimator prototyping work and the beam test facility! Was defined top-down. Less than originally hoped from EU.

•
Strategic input required
before we can invest more work.
Can the accelerator sector top management support:
– The approach taken (test risky elements before installation into the LHC, one common beam test facility for qualification and analysis of different near beam devices).
– The proposed solution (WANF).
• If not supported:
What alternatives should be considered?
• If our proposal is supported, then we suggest to move ahead:
– Define detailed work packages and budgets for various groups.
– Start procurement procedures (orders, MS, call for tender, …).
– Agree with SLAC formally on deliverables (pending DOE support).
– Present details in March/April 2009 collimation phase II project review for final approval.
Candidate dates for review: March 19/20 – Mar 31/Apr 1 – Apr 28/29 R. Assmann, 26.1.2009
