Specific examples of ongoing workfrom collaborations and major countries

Summary

ILC@KEKNov. 13th, 2004

General outline of ILC-related collaboration in Europe.

Important areas for future work


2

Euro Collaborations

TESLA (wider than Europe alone)

Coordinated Accelerator Research in Europe

EuroTeV - LC research programme

UK Linear Collider Accelerator & Beam DeliveryLCABD – PPARC & CCLRC-funded

European XFEL


3

TESLA

55 Institutes in 12 countries(43 institutes 9 countries in Europe).

Successful (ever growing) collaboration for over a decade.

Responsible for developing SCRF to the point where it is a viable option for a Linear Collider.

TESLA collaboration continues to evolve:- no longer a collaboration focused on ILC; - many institutes interested in ‘technology’ (for light sources, ERL etc.);- ‘mission’ now to advance SCRF technology(main customers: XFEL, ILC, Proton Driver…)

German government Feb. 2003 gave go-ahead for XFEL as European project, incl. funding 50% of total 684 M€ (year 2000) project cost, + contribution from Länder HH & Schleswig-Holstein. ~ 40% required from European Partners.

Project currently being organised at European Level (scientific/tech. & admin./financial) ongoing- to be completed by 2005.

In Sep. 2004, 9 European countries decided to sign MoU for project preparation phase.

Other UK interestsRF system components:

industrial interest in engineering prototypes of klystrons, modulators, couplers . Nb cavity&module assembly + system tests: synergy with 4GLS project.

Damping ring design: long experience from SRS to DIAMOND/4GLS;synergy with Diamond 3rd gen light source.

Diagnostics, feedback, control:BPMs, charge monitors, FB etc. beyond BDS - SRS, Diamond experience

Electron source: RF photocathode: synergy with 4GLS. Long experience with lasers in many applications.

Vacuum science & general beam dynamics: electron cloud, NEG pumping etc.

CDR&TDR production will require LOTS of generic accel.engineering expertise– of which UK has much.

23

Spain & Russia

Spain has contributed to SC magnets for TTF and XFEL and has also looked at optics design and collimation systems.

They plan to look at corrector magnets, kickers and septum and RF structures for CTF3 and optics design, beam dynamic simulation and instrumentation in the spent beam line (MDI) and very forward detector region from 2005.

Russia has a long-standing interest in ILC-related issues – from INP in Novosibirsk on (polarized) positron production, storage rings, final focus, accelerator structures, etc. Theyexpect to expand this participation as the needs of the ILCand the GDI become better defined.

Important issues for GDIMain LINAC is still the biggest challenge: Cost driver; complexity; reliability; sheer number of components Priority must go now to Engineering! QA/QC cavity production → 35MV/m. Design / testing of tuner(s), couplers, etc.- Test facilities for long-term reliability testing.Qualification of klystrons / ModulatorsINDUSTRIALISATION - Cost reductionAll other sub-system design (inc. parameterspecifications) can run in parallel.Linac tech. is a building block which is quite flexibleAt all design consideration stages, $$-impact must be included.At all design consideration stages, $$-impact must be included.The number of ILC meetings is proliferating. This is good!However, we risk drowning in meetings. Until GDI is working,we need someone to be responsible for optimally coordinatingmeetings. We should agree this by the end of this meeting.


26

SummaryThere is a lot of work going on in Europe either directly on, or closely related to, the ILC. Much of that work is carried out in the context of large multinational collaborations, which are often relatively inflexible and have well defined deliverables and milestones. The total European resource relevant for ILC R&D over the next 3 years is ~100M€. Europe is conscious of the need to work out structures by which resources can be devoted to issues the GDI identifies as critical.We have identified several areas of the current designs on thetable where work is needed; we believe that in some we have the necessary resources and expertise to play a leading role.We look forward to implementing the GDI and taking thenext steps to the realisation of the ILC as rapidly as possible.
