News from ILC Ø GDE structure founded under B. Barish: 3 GDE regional Directors + ~40 CORE team (4 from ELAN managt) under ILCSC ‘oversight’ Snowmass meeting (ALCPG->Intal) 2 weeks in August to reach ILC configuration - Physics (Aspen), Detector, Accelerator (after Ke. K) - 640 participants (1/3 machine) - 10 critical recommendations/decisions Ø EUDET: I 3 for detector approved 7 M€ 21 partners Ø 2

GDE – Staffing Staff the GDE l Administrative, Communications, Web staff l Regional Directors (one per region) l Accelerator Experts (covering all technical areas) l Senior Costing Engineer (one per region) l Civil/Facilities Engineer (one per region) l Detectors (WWS chairs) l Fill in missing skills (later) Ø Total staff size about 20 FTE (2005 -2006) about 40 heads. Ø The internal GDE organization and tasks will be organized internationally, not regionally Ø 3

GDE – Near Term Plan Ø Schedule • Begin - define Configuration (Snowmass Aug 05) • Baseline Configuration Document (end of 2005) ----------------------------------- • Baseline under Configuration Control (Jan 06) • Develop Reference Design (end of 2006) • Coordinate the supporting R&D program Ø Three volumes -- 1) Reference Design Report; 2) Shorter glossy version for non-experts and policy makers ; 3) Detector Concept Report 4

ELAN Documents 17

Conclusion ELAN activity is mainly driven by the international GDE (WG 3 -4) Ø ELAN support has been instrumental in preparing and supporting the Snowmass meeting Ø European support has been essential and should be maintained within FP 7 Ø Ø Interesting prospects of collaboration with the laserplasma community 18

From ECFA (T. A. ) ICFA beam dynamics panel, Weiren Chou, European co-sponsoring of a linear collider (more specifically ILC) school in spring 2006 in Japan. He has contacted Japan (JSPS) and the USA (DOE) about co-sponsoring and sent a mail to T. A. about "which European agency to contact". Quantitatively we talk about 40 -55'000 euros, assuming 20 -25 students and 6 -8 lecturers from Europe. Ø 19
