1. 18.12.07 DRWS07 KEK Global Design Effort 1 2007 ILC Damping Rings Mini-Workshop 18-20 December, 2007 High Energy Accelerator Research Organization KEK, Tsukuba, Japan Marc Ross GDE

2. 18.12.07 DRWS07 KEK Global Design Effort 2 Role of R & D in the Engineering Design Goals of the ED Phase: Reduce cost and risk –Technical Facilitate governmental (and inter- governmental) discussions –“…engineering design of the project in sufficient technical detail that approval from all involved governments can be sought,…” –Political Update the design, and the value estimate, and provide a project plan

3. 18.12.07 DRWS07 KEK Global Design Effort 3 R & D Plan Prioritization based on expected ‘cost / benefit’ Top-3 identified: –High Gradient cavities –CFS ‘value engineering’ ◄ –Beam test facilities (7 each) ◄ (ATF, CESR-TA, …) Expect to update this list in next 2 months, leading up to the Tohoku GDE meeting 03.03.2008 Impact on DR plans

4. 18.12.07 DRWS07 KEK Global Design Effort 4 Prioritization of ED Phase R & D Based on –Direct ‘value estimate’ impact Second e+ DR CFS design –Technical risk Risk ‘register’ developed mid-2007 –Schedule Which activities can provide guidance by the time EDR is to be completed? –July 2010 What do we really need? –What would be useful? What would be important as we get underway?

5. 18.12.07 DRWS07 KEK Global Design Effort 5 ED Phase R & D Plan To be published 01.2008 –Written by PM, with help from Group Leaders (Wolski, Seryi,…) and regional/institutional managers Describes top-3, with schedule and etc Lists resources hoped-for, worldwide –Allows funding agency managers to compare Describes management outline –(not management detail for top-3) –(this should be developed in next 3 months)

6. 18.12.07 DRWS07 KEK Global Design Effort 6 From R & D Plan – top 3: (1) Superconducting cavity testing:

7. 18.12.07 DRWS07 KEK Global Design Effort 7 CFS Requirements and VE (2)

8. 18.12.07 DRWS07 KEK Global Design Effort 8 Beam Test Facility (3)

9. 18.12.07 DRWS07 KEK Global Design Effort 9 What will the above cost? Are these goals feasible Group Leaders, WP coordinators must answer –Answer must be supported by existing / expected institutional and regional support What else is there that belongs on this list? –Kickers –Impedance

10. 18.12.07 DRWS07 KEK Global Design Effort 10 For Tohoku GDE meeting: (from this workshop?) Develop plan for 3 subtopics, including details –Purpose, overall goal, how it fits in –Activities, Problems –Schedule –Milestones, deliverables –Resources –Priorities Review progress before GDE meeting

11. 18.12.07 DRWS07 KEK Global Design Effort 11 UK groups – we support you: Excerpts from Barry’s letter to John Denham, Dec 15: (italics mcr) “A global effort has been organized toward these goals, involving an unprecedented collaboration of leading accelerator physicists from around the world working jointly on the R&D and design of this very challenging concept.”

12. 18.12.07 DRWS07 KEK Global Design Effort 12 Emphasis on your leadership role “It is no accident that these UK accelerator physicists have risen to leadership roles in the ILC, based almost solely on their intellectual efforts. I strongly urge that the UK reconsider its role on the ILC, and especially in regard to preserving support for the intellectual effort that has been so effective.”

13. 18.12.07 DRWS07 KEK Global Design Effort 13 and on ‘consensus – based’ design “Our plan in the ILC global design effort is to pursue the R&D to develop the concepts for the ILC, so that it will be possible to propose such a machine in the future. Whenever the ILC is proposed, it will have uniquely been created as the product of a combined worldwide collaboration of accelerator scientists and particle physicists.” These are the marks of a multi-lateral collaboration with genuine international support.
