1 The Design & Value Costs SRF Technology The XFEL as a Prototype Japan as a Host International Linear Collider Status Mike Harrison

2 A Global Initiative for an ILC International Committee for Future Accelerators (ICFA) representing major particle physics laboratories worldwide. Chose ILC accelerator technology (SCRF) Determined ILC physics design parameters Formed Global Design Effort and Mandate 2006

3 Technical design completed and reviewed (PAC Dec 2012). TDR completed. Value cost estimate of $7.6B based on TDR M man-hrs of explicit labour (~$2B). Value estimate does not cover US specific cost elements such as escalation, contingency, pre-ops, etc. Generic site(s): flat terrain & mountainous Using “reasonable” assumptions, ~9 years from ground breaking to start of beam commissioning Technical Design Completed Dec 2012 Mike Harrison

32 Technical focus will shift to cryomodules via the XFEL production Site specific conceptual design next step Value engineering on linac systems The US R&D program ends with the GDE. Awaits further development towards a project Japan seriously considering offering to host New global collaboration after the GDE. It contains all the linear collider activities, not just the ILC.
