10. 20-Nov-06 FALC - KEK Global Design Effort 10 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

11. 20-Nov-06 FALC - KEK Global Design Effort 11 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 2-2.5 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

12. 20-Nov-06 FALC - KEK Global Design Effort 12 CMS assembly approach Assembled on the surface in parallel with underground work Allows pre-commissioning before lowering Lowering using dedicated heavy lifting equipment Potential for big time saving Reduce size of underground hall required On-surface assembly

18. 20-Nov-06 FALC - KEK Global Design Effort 18 Reviewing RDR & Costs

20. 20-Nov-06 FALC - KEK Global Design Effort 20 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.

21. 20-Nov-06 FALC - KEK Global Design Effort 21 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

22. 20-Nov-06 FALC - KEK Global Design Effort 22 Proposed RDR Review Process

23. 20-Nov-06 FALC - KEK Global Design Effort 23 Presentation Strategy The GDE is purposefully constituted as a tri-regional design team whose goal is to produce by 2009 a Technical Design Report (TDR) which will contain a detailed, engineering-based design and cost for the ILC. The initial step towards the TDR was to establish a Reference Design Report (RDR) which will define a self-consistent set of ILC design parameters and associated implementation scope. The RDR also contains an initial estimate of cost at the 20% level which is mostly parametric in nature. This initial cost estimate is at sufficient detail to permit a) trend analysis for cost reduction/optimization and b) give guidance for the R&D and industrialization that must accompany the engineering design process of the TDR.

24. 20-Nov-06 FALC - KEK Global Design Effort 24 Cost Review Guideline An international team should be convened prior to completion of the RDR to review those aspects of the RDR cost estimate that strongly influence the TDR. Given the intermediate nature of the RDR estimate as discussed above, it would seem premature to review in detail every aspect of an ILC cost estimate. Rather this review team should: –review cost trends and relative costs of sub-systems as they relate to potential scope changes to be incorporated in the TDR –review cost trends and relative costs of sub-systems and comment on their relevance to the R&D program needed to complete the TDR –review the methodology used in the estimate to ensure that it is appropriate for establishing an accurate TDR cost assessment. Evaluate that the method and format of estimation can serve the needs of regional authorities as they develop plans for potential involvement as partners in the ILC

25. 20-Nov-06 FALC - KEK Global Design Effort 25 Siting Aspects of RDR & Candidate Sites

26. 20-Nov-06 FALC - KEK Global Design Effort 26 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.

27. 20-Nov-06 FALC - KEK Global Design Effort 27 Costs by Technical & Global System

28. 20-Nov-06 FALC - KEK Global Design Effort 28 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
