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

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

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?

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)

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

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

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.”

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.”

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.
