Nick Walker, Brian Foster LAL, Orsay WP2: Coordination with the GDE

GDE - Status GDE has successfully completer Phase 1 of the Technical Design Phase Publication of comprehensive interim report: International Linear Collider: A Technical Progress Report –ILC-HiGrade-Report Phase 2 now underway, shifts emphasis away from risk-mitigating R&D towards preparation for the final Technical Design Report (TDR end 2012): –Consolidation and review of final design baseline and associated documentation –Preparation of updated Cost Estimate –Industrialisation of SCRF and global mass production studies N. Walker (DESY) - ILC-HiGrade Annual Meeting (LAL, Orsay) 2

Coordinating with the GDE N. Walker (DESY) - ILC-HiGrade Annual Meeting (LAL, Orsay) ILC-HiGrade has remained tightly coordinated with GDE activities –Via key European management No fundamental change during TDP –exception: Steinar Stapnes (CERN) replaces Jean-Pierre Delahaye in GDE Exec.

XFEL, ILC-HiGrade & GDE ILC-HiGrade participants reflect strong GDE-XFEL synergy (European strength), and are also active participants in the ILC-GDE N. Walker (DESY) - ILC-HiGrade Annual Meeting (LAL, Orsay) ◉ DESY LAL, Saclay INFN Milan CERN ◉ OXUN 6 ◉ ◉ ◉ ILC-HiGrade ILC-HiGrade to provide QA/QC for XFEL cavity production -Focus on achieving consistent ILC gradient performance Now focused on XFEL input into -Cavity and Cryomodule Mass production -Costs (XFEL → ILC production levels)

SCRF Cryomodule Mass Production Studies ILC-HiGrade will coordinate European industrial studies on ILC- level production of cavities and cryomodules. –18,000 cavities –17,00 cryomodules Build on two sources of input –XFEL production of ~100 cryomodules (800 cavities) –TESLA industrial studies for 20,000 cavities (year 2000) Currently updating TESLA studies –Research Instruments (cavity) –Zanon (cavity) –Babcock Noell (string assembly) CERN-based model of string assembly –similar to LHC experience Studies to be complete mid-2012 –Provide European input into GDE TDR cost estimate N. Walker (DESY) - ILC-HiGrade Annual Meeting (LAL, Orsay) 7 XFEL experience

The GDE Technical Design Report Primary TD Phase deliverables: –Updated design of the machine –Updated VALUE estimate –Project Implementation Plan –Results and conclusions from worldwide Risk-mitigating R&D TDR will be three volumes* –Executive Summary –Part I:Results of Risk-Mitigating R&D –Part II: ILC Baseline Design, including Comprehensive design document Cost and schedule Project Implementation Planning ILC-HiGrade has already provide input at many levels N. Walker (DESY) - ILC-HiGrade Annual Meeting (LAL, Orsay) *Not including Physics and Detector volumes

Coordination requires Communication GDE (and ILC-HiGrade) is a worldwide (European) distributed collaboration Face-to-face meetings (workshops) remain critical for progress –And team building! However, primary (weekly) contact remains via remote conferencing N. Walker (DESY) - ILC-HiGrade Annual Meeting (LAL, Orsay)

Relevant European Workshops TESLA Technology Collaboration meeting –INFN Milan, ILC Damping Ring Baseline Technical Review –INFN Frascati, st European SRF Industrialisation Meeting –CERN, rd European SRF Industrialisation Meeting –CERN, LCWS ‘11 –Granada, – together with Physics & Detector community ILC central region Baseline Technical Review –DESY, ILC CFS meeting –DESY ILC cost management meeting –DESY N. Walker (DESY) - ILC-HiGrade Annual Meeting (LAL, Orsay) 10

Summary ILC-HiGrade integration into the GDE remains at the highest level and is essentially unchanged GDE is now shifting focus to the preparation of the TDR, including updated cost estimate ILC-HiGrade co-coordinating European industrial study effort for SRF –As part of the GDE global effort Other key areas of TDR input now quite mature –Governance (Project Implementation Planning) –Siting (CERN and Dubna sites) N.
