1-Dec-06 HEPAP Univ. Subpanel Global Design Effort 9 2/20 mrad  14/14 mrad Motivation –Reduce costs 2 mrad beam line expensive, risky, especially extraction line Common collider hall –Advantages Improved radiation conditions in the extraction lines Better performance of downstream diagnostics Easier design and operation of extraction optics and magnets Reduced back scattering from extraction line elements –Disadvantages Impact on physics (appears minor at present). Simpler incoming beam optics R&D on small crossing angles will continue as alternative

1-Dec-06 HEPAP Univ. Subpanel Global Design Effort 10 On-surface Detector Assembly Vancouver WBS considered the underground halls sized at 32m (W) x 72m (L) each to allow underground assembly of the largest considered detector. Conventional Facilities Schedule gives detector hall is ready for detector assembly 5 yrs from project start –If so, cannot fit our goal of “7years until first beam” and “8years until physics run” Surface assembly allows to save years and allows to fit into this goal –The collider hall size may be smaller (~40-50%) in this case –A building on surface is needed, but savings may be still substantial Optimization needs to be done

1-Dec-06 HEPAP Univ. Subpanel Global Design Effort 13 Push-Pull Evaluation Initiated by GDE & WWS at the end of September Detailed list of questions to be studied developed: Large group of accelerator and detector colleagues, from ILC and other projects, is participating in design and discussion of these question The task force of detector experts was formed to contribute to detailed evaluation of the whole set of technical issues

1-Dec-06 HEPAP Univ. Subpanel Global Design Effort 16 RDR Report RDR is a high level description of the accelerator, CFS, sites and costs A snapshot of what we propose to build –not a history of R&D, design evolution, and alternatives Editors: –Nan Phinney (SLAC), Nobu Toge (KEK), Nick Walker (DESY) Original schedule was complete draft now, but has been pushed back because of cost iterations

1-Dec-06 HEPAP Univ. Subpanel Global Design Effort 19 Charge for MAC Review On Wednesday 10, Thursday 11 and Friday 12 (until noon) January 2007, there will be an ILC MAC meeting at the Cockcroft Institute, Daresbury, UK. The major item for the meeting is the ILC cost and overall design, with specific MAC tasks: –Review the soundness of the overall RDR concept, identify any areas of concern, note what R&D is still needed, and comment on whether the performance parameters can be met. –Review the cost methodology and identify any areas of concern. This will be the first occasion at which costs will be presented outside of the GDE.

1-Dec-06 HEPAP Univ. Subpanel Global Design Effort 20 What Happens after Beijing? Public Release of Draft RDR and Preliminary Costing at Beijing –Cost Reviews, etc –Finalize RDR by Summer 2007? Enter into Engineering Design Phase –Planning underway internally –Design will evolve through value engineering and R&D program –General Goal is to have Construction Proposal ready by 2010

Make narrow definition for “host costs” - goal ~ 25% of total.

1-Dec-06 HEPAP Univ. Subpanel Global Design Effort 25 Site Aspects of RDR Three Samples Sites –ILC Conventional Facilities Group: Jean-Luc Baldy (CERN), Vic Kuchler (Fermilab) and Atsushi Enomoto (KEK) + Support Group –Sample Site Analysis - Europe (CERN); Japan (?); US (Fermilab) also, TESLA for reference and Russia unsolicited –Conventional Facilities are expensive! Make narrow definition for “host costs” - goal ~ 25% of total. Costing Regional – Best estimates in “own” system of costing. They are close to equal, meaning the RDR siting chapter can concentrate on requirements, technical features, cost drivers, safety issues, other issues etc. Need “true” candidate sites within ~ 1-2 years for realistic engineering design. How do we solicit candidate sites

1-Dec-06 HEPAP Univ. Subpanel Global Design Effort 30 Some Key Issues The RDR –The RDR is a snapshop of the concept and scope of the costs; NOT A MATURE DESIGN –It is an “optimized concept” for the physics scope (ILCSC parameters) without doing detailed engineering (value engineering) and future R&D (demonstrations and alternatives) –Engineering Design will be more cost effective, lower risk and maintain the physics scope. Next Phase – Expensive –Resources and Organization ??? –Involve University Community in Acc Design/ R&D –Detector R&D  Road map - collaborations/detectors
