ILC Project Implementation Planning • Contents • Executive Summary • Governance • Funding Models • Project Management • Host Responsibilities • Siting Issues • In-Kind Contribution Models • Industrialisation and Mass Production of the SCRF Linac Components • Project Schedule • Future Technical Activities Global Design Effort

  19. Project Implementation Planning Global Design Effort

  20. (Global) Mass Production (SCRF) PIP Governance TLCC-1 Global S1 TDP-2 • Critically important TDP2 activity • Learn from XFEL experience • 5% ILC • Learn from LHC experience • Develop realistic models on which to base cost estimate • With industry SCRF Global Design Effort

  22. KEK Industrial R&D Pilot Plant 19m x 14m ISO class-5 clean room Chemical Polish room Electron Beam Welder Press machine Triming machine work together with industry to develop cost-effective cavity production techniques Global Design Effort

  23. Systems Tests TDR Post - TDR Global Design Effort

  24. Global Design Effort

  25. FLASH: Stability • 15 consecutive studies shifts (120hrs), and with no downtime • Time to restore 400us bunch-trains after beam-off studies: ~10mins • Energy stability with beam loading over periods of hours: ~0.02% • Individual cavity “tilts” equally stable Energy stability over 3hrs with 4.5mA ~0.02% pk-pk Global Design Effort 9 Feb 2011

  26. Fermilab – NML SRF Schedule Global Design Effort

  27. KEK – STF Plans for Cryomodule Tests Global Design Effort

  28. TDR Cost Estimate “Value Costs” - Plans and Scope Comparisons with RDR costs Global Design Effort

  29. TDR Cost estimate: Scope • The cost estimate covers only the costs for the 500 GeV design as detailed in the TDR, to be expended during the 8 year construction period. • Costs for project engineering and design, R&D prior to construction authorization, commissioning, pre-operation, operation, and de-commissioning are not included. • Costs for upgrading the machine to 1 TeV are not included in the baseline estimate, except the cost of those systems which would be very difficult to provide after construction of the 500 GeV machine. • An approximate cost for the 1 TeV upgrade will be provided separately.

  30. OECD PPP (Yen/USD)-annual average by year PPP = Purchasing Power Parity EX-exchange rate GDP: PPP based on all goods/services in GDP of each region M&E: PPP based on machinery and equipment Const: PPP based on civil construction Full PPP determinations were done for 2005 and 2008; other year points based on GDP inflation rates Global Design Effort

  35. Extending the reach of the ILC • ICFA LC Parameters subcommittee (2003 and 2006) Global Design Effort

  36. Extending the reach of the ILC • Upgrade option for study: • - Power < 300MW AC • - New linac grad = 45 MV/m • - Q0 = 2 1010 • Strawman TeV parameters • Post-TDR program: • Improve cavity gradient • Cost effective production • Flexibilty: Initial ILC energy: higher or lower energy, as informed by LHC results Global Design Effort

  37. Post-TDR ILC Interim Goals & Organization • GDE will have successfully completed its mandate after TDR & PIP delivered + reviewed (mid-2013 at latest + transition) • What should follow GDE (mandate and organization) for an interim 3-5 year period? (ILCSC – Bagger) • GDE position paper submitted to ILCSC Aug 2011. The paper addresses: • Technical Goals proposed for 2012+ program? • Value engineering; Continued system demonstrations; Increasing energy reach; + • Organizational Issues for 2012+ post GDE? • What are primary GDE assets that should be preserved? • What are the primary GDE weaknesses that should be improved? • We must define what systems tests must demonstrate for each LC option before construction of a LC?

  43. Conclusions • The major R&D milestones for TDR are essentially in-hand • The Technical Design Report will be a self-contained comprehensive R&D report; with a design based on new baseline; a new value costing; and a section on project implementation planning • We seek your advice / concurrence on our system tests goals and program • Post–TDR program is being planned: extend energy reach; complete systems tests; evolve design based on technology development and LHC results Global Design Effort
