3. The only way to restore the luminosity is to crush the beams to a tiny volume so that one pass gives all the particles the same chance to interact that many passes gives less dense bunches. The ILC is a linear collider – thus there is no synchrotron radiation produced in bending e+e- in a circular orbit. The challenges stem from this – in circular machines, the beams pass through each other many times/ second, giving many chances for interaction – “luminosity”. In ILC, they pass through each other once and then are dumped. Because radiated synchrotron-radiation power goes like m-5, circular e+e- colliders bigger than LEP (the previous CERN machine) are uneconomical. We didn’t know how to build complementary machines (like Tevatron (p-antip) and LEP) when LHC was proposed. Now we do – the ILC. Why/what is ILC? Brian Foster - Cosener's Forum May 06

4. There will only be one machine like this in the world – so it is essential that world-wide agreement be obtained. This has been in place for ~3 years. TESLA was the catalyst that in the last four years has moved the ILC forwards very rapidly. HEPAP report: “We recommend that the highest priority of the U.S. program be a high-energy, high-luminosity, electron-positron linear collider, wherever it is built in the world…. We recommend that the United States prepare to bid to host the linear collider, in a facility that is international from the inception.” ECFA report: “..the realisation, in as timely a fashion as possible, of a world-wide collaboration to construct a high-luminosity e+e- linear collider with an energy range up to at least 400 GeV as the next accelerator project in particle physics; decisions concerning the chosen technology and the construction site for such a machine should be made soon” ACFA: “ACFA urges the Japanese Government to arrange a preparatory budget for KEK to pursue an engineering design of the collider, to study site and civil engineering, as well as to investigate the process for the globalization.” Status of the ILC Brian Foster - Cosener's Forum May 06

5. In January 2004 the Science Ministers of the OECD met in Paris and, following the detailed work of a GSF Consultative Group on particle physics that produced a road Map, agreed a statement on the Linear Collider: Ministers “acknowledged the importance of ensuring access to large-scale research infrastructure and the importance of the long-term vitality of high-energy physics. They noted the worldwide consensus of the scientific community, which has chosen an electron-positron linear collider as the next accelerator-based facility to complement and expand on the discoveries that are likely to emerge from the Large Hadron Collider currently being built at CERN. They agreed that the planning and implementation of such a large, multi-year project should be carried out on a global basis, and should involve consultations among not just scientists, but also representatives of science funding agencies from interested countries. Accordingly, Ministers endorsed the statement prepared by the OECD Global Science Forum Consultative Group on High-Energy Physics (see Appendix).” Status of the ILC Brian Foster - Cosener's Forum May 06

6. Despite the fact that both US and Asian research had been in warm technology, both regions accepted the decision and united behind cold technology; now, transition is complete. In August 2004, group of “Wise Men”, chaired by B. Barish, chose the “cold”, superconducting, RF technology over the competing “warm” X-band RF. B. Barish appointed as GDE director, with three regional directors: BF (Europe), F. Takasaki (Asia), G. Dugan (Americas) ICFA moved ahead quickly to appoint a Global Design Effort (GDE) to transform the technology decision into a full Technical Design Report, capable of being presented to world governments for a decision to construct.

7. P. Burrows was a member of the EPP2010 committee and can give more details at he end of my talk. At end of April, EPP2010 panel produced its report. This gave a ringing endorsement for the ILC strategy and strong support for the US bidding to host the machine. Status of the ILC Brian Foster - Cosener's Forum May 06

17. BCD is complete. In the next phase, RDR will take forward the BCD, refine the design and in particular gather industrialisation data in order to form the basis for reliable cost estimate with the RDR. There are 3 new boards: Change Control Board; Global R&D Board; Design & Cost Board. Next steps for GDE Brian Foster - Cosener's Forum May 06

18. FALC ICFA FALC Resource Board ILCSC MAC GDE Directorate GDE Executive Committee GDE R & D Board GDE Change Control Board GDE Design Cost Board Global R&D Program RDR Design Matrix Next steps Brian Foster - Cosener's Forum May 06

19. The board has overseen the consolidation of the baseline design and the production of a Word document containing all information. Dealing with requests for changes to baseline as further work and R&D is completed. During process, all GDE members can comment on proposed change. Dealing with ~ 1 request/week. Careful methodology developed - categorise the importance of the change, assign number of board members to review it depending on importance. Change control Brian Foster - Cosener's Forum May 06

20. Design & cost board produced a (very) • detailed programme of work to lead us • towards the most important RDR deliverable • a believable, robust and affordable costing; • a preliminary, non-public version will be • available by the summer Vancouver meeting. • R&D board has to try to impose a structure • and discipline on inherently chaotic system • R&D - eliminating wasteful duplication • while preserving & enhancing necessary • duplication. Other boards Brian Foster - Cosener's Forum May 06

21. The RDR will be produced using a matrix structure of “area systems” and “technical systems” to account for the project structure. Next steps for GDE Brian Foster - Cosener's Forum May 06

22. The WBS Next steps for GDE Brian Foster - Cosener's Forum May 06

23. The meetings are going well and detailed progress is being made. The day-to-day work of constructing the RDR will be supervised by an RDR board chaired by N. Walker (DESY) which will meet every week by telephone and report to the ILC Executive Committee. Next steps Brian Foster - Cosener's Forum May 06

24. Generally they were very positive and impressed by the scale of the progress that has been made. They had concerns about the current accelerating gradient spec. and how R&D could be done to achieve it, about communications with the experimenters and also about the coordination of world-wide R&D. The first meeting of the Machine Advisory Committee, which reports to ILCSC, took place last month in Fermilab. MAC report Brian Foster - Cosener's Forum May 06

Detectors - 4th concept Brian Foster - Cosener's Forum May 06

29. European GDE meets about every 6 months. • Discusses obviously regional issues: • how to get more resources from inside • Europe, in particular the EU; • - regional outreach - Europe has particular • difficulties & challenges here. The European GDE does NOT discuss the technical issues of the BCD or take up European positions on them - these are matters for the full GDE. European GDE Brian Foster - Cosener's Forum May 06

30. Two meetings in CERN to explore in particular the similarity between LHC and ILC cryogenics and to utilise CERN expertise, particularly in civil engineering. Very encouraged by the great interest on the ground in CERN in the project, the very constructive and positive meetings we have had and the growing involvement of CERN staff in the ILC. European GDE Brian Foster - Cosener's Forum May 06

31. European Outreach group re-established at Orsay meeting in January. B. Warmbein joined the team recently as PA to EGDE director, based at DESY. Meeting held in DESY just before Easter. EGDE director’s advisory group also meets regularly. Discussed plans for FP7 initiative for European cryogenic RF development centre based probably at one of big labs. LoI for such a facility was input to CERN Council Strategy group. European GDE Brian Foster - Cosener's Forum May 06

32. There is an EGDE meeting in DESY next week to discuss the shape of the FP7 proposal. It will hear about European cryogenic RF development centre, about possible continuation of some current FP6 activities, the use of HERA as a prototype damping ring, etc. European GDE Brian Foster - Cosener's Forum May 06

33. EGDE director’s advisory group also meets regularly to advise on strategy, particularly for R&D. It is clear that world-wide coordination of R&D is going to be an important issue in the future and we need to think about how this can be achieved; Europe has particular features that make this a challenge.

36. The ILC is making excellent progress and the GDE is well established. Producing the RDR & the cost estimate by the end of the year is going to be very tough - we need all the help & expertise that we can get. This is a very exciting and challenging enterprise that is vital for the future of world particle physics. Summary Brian Foster - Cosener's Forum May 06
