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

• Technical design completed and reviewed (PAC Dec 2012). TDR completed.
• Value cost estimate of $7.6B based on TDR + 22.6M 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

Cavity Production Yield
XFEL Cryomodule Cost breakdown
• 8 cavities + 1 sc quad– ~12 m cryomodule
• Including testing– cavity vertical test– cryomodule pulsed test
• Testing
– Assumes 100% DESY infrastructure
– 100% testing– second largest cost driver

• 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.
