Brian Foster - Cosener's Forum May 06 1 The ILC - Status & Plans Introduction & latest developments The GDE The baseline design and R&D efforts The path to the RDR The EGDE & summary

Brian Foster - Cosener's Forum May 06 2 Status of the ILC In August 2004, group of “Wise Men”, chaired by B. Barish, chose the “cold”, superconducting, RF technology over the competing “warm” X-band RF. 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. 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. B. Barish appointed as GDE director, with three regional directors: BF (Europe), F. Takasaki (Asia), G. Dugan (Americas) M. Nozaki

Brian Foster - Cosener's Forum May 06 3 Status of the ILC At end of April, EPP2010 panel produced its report. This concluded that it was very important that the US regained its leading position in particle physics, under clear threat with the closure of all US domestic pp accelerators by end of the decade. It gave a ringing endorsement for the ILC strategy, requested increased US investment in the R&D for both machine and detector and gave strong support for the US bidding to host the machine. The CERN Strategy group met last week in Zeuthen. Although its conclusions remain confidential, I believe that the current draft document to be submitted to the special CERN Council Session in July contains a strong endorsement of the ILC and a recommendation that Europe, and CERN, are strongly involved in it through the GDE.

Brian Foster - Cosener's Forum May 06 4 GDE mission Currently GDE is 64 strong : Americas - 22; Asia - 18; Europe - 24; corresponding to ~ 30 FTEs. Produce a design for the ILC that includes a detailed design concept, performance assessments, reliable international costing, an industrialization plan, siting analysis, as well as detector concepts and scope. Coordinate worldwide prioritized proposal driven R & D efforts (to demonstrate and improve the performance, reduce the costs, attain the required reliability, etc.)

Brian Foster - Cosener's Forum May 06 6 BCD overview Baseline Design completed in December 2005 overseen by Executive: Directors + T. Raubenheimer, N. Walker, K. Yokoya.

Brian Foster - Cosener's Forum May 06 7 Energy Upgrade

Brian Foster - Cosener's Forum May 06 8 MAC report 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 coordination of world-wide R&D. The first meeting of the Machine Advisory Committee, which reports to ILCSC, took place last month in Fermilab & examined the BCD.

Brian Foster - Cosener's Forum May Klystron Fabrication Several suppliers for BCD: But none meet performance requirements - may need to go to 5 MW.

Brian Foster - Cosener's Forum May Test facilities TTF exists at DESY, SMTF (FNAL), STF (KEK): Stimulate SC industry in the regions - collaborate on SC technology

Brian Foster - Cosener's Forum May Next steps for GDE 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.

Brian Foster - Cosener's Forum May Change control 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. Careful methodology developed - categorise the importance of the change, assign number of board members to review it depending on importance. During process, all GDE members can comment on proposed change. Dealing with ~ 1 request/week.

Brian Foster - Cosener's Forum May Other boards 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.

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

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

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

Brian Foster - Cosener's Forum May European GDE 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.

Brian Foster - Cosener's Forum May European GDE 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.

Brian Foster - Cosener's Forum May European GDE Yesterday evening we had an EGDE meeting in DESY to discuss the shape of the EU FP7 proposal. We heard about European cryogenic RF development centre to be cited at CERN, about possible continuation of some current FP6 activities, the use of HERA as a prototype damping ring, etc. ELAN/EuroTeV Meeting at Orsay next Mon-Weds will also discuss these ideas. Goal to have an action plan & outline strategy in next few weeks.

Brian Foster - Cosener's Forum May Summary 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.
