1 Brian Foster - Cosener's Forum May 06 1 The ILC - Status & Plans Why/what is the ILC? The GDE The baseline design and R&D efforts The path to the RDR Detectors The EGDE & summary

2 Brian Foster - Cosener's Forum May 06 2 Why/what is ILC?

3 Brian Foster - Cosener's Forum May 06 3 Because radiated synchrotron-radiation power goes like m -5, circular e + e - colliders bigger than LEP (the previous CERN machine) are uneconomical. We didnt 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? 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. 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.

4 Brian Foster - Cosener's Forum May 06 4 Status of the ILC TESLA was the catalyst that in the last four years has moved the ILC forwards very rapidly. 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. 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 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. 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.

5 Brian Foster - Cosener's Forum May 06 5 Status of the ILC 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).

6 Brian Foster - Cosener's Forum May 06 6 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

7 Brian Foster - Cosener's Forum May 06 7 Status of the ILC 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. P. Burrows was a member of the EPP2010 committee and can give more details at he end of my talk.

8 Brian Foster - Cosener's Forum May 06 8 GDE –The Mission of the GDE Produce a design for the ILC in 3 stages - BCD, RDR and TDR, 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.)

10 Brian Foster - Cosener's Forum May ILC Parameters E cm adjustable from 200 – 500 GeV Luminosity Ldt = 500 fb -1 in 4 years Ability to scan between 200 and 500 GeV Energy stability and precision below 0.1% Electron polarization of at least 80% The machine must be upgradeable to 1 TeV

11 Brian Foster - Cosener's Forum May BCD overview The ILC Baseline Design was completed in December 2005: Process overseen by ILC Executive - B. Barish, G. Dugan, BF, F. Takasaki, T. Raubenheimer, N. Walker, K.Yokoya. E. Elsen will give details.

12 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

13 Brian Foster - Cosener's Forum May Test facilities KEK has been a great success. Time for further improvement:

14 Brian Foster - Cosener's Forum May Test facilities Extend ATF to give FF prototype - squeeze down to 35 nm and stabilise to 2 nm.

15 Brian Foster - Cosener's Forum May ILC Communications Launch of New ILC Snowmass One Stop Shopping –electronic data management system (EDMS), news, calendar of events, education and communication

16 Brian Foster - Cosener's Forum May 06 16

17 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.

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

19 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.

20 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.

21 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.

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

23 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 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.

24 Brian Foster - Cosener's Forum May 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 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.

25 Brian Foster - Cosener's Forum May Detectors - SiD

26 Brian Foster - Cosener's Forum May Detectors - LDC

27 Brian Foster - Cosener's Forum May Detectors - GLD

28 Brian Foster - Cosener's Forum May Detectors - 4th concept Pixel Vertex (PX) 5-micron pixels TPC (like GLD or LDC) with silicon strips on outer radius Crystal dual-readout ECAL Triple-readout fiber HCAL: scintillation/Cerenkov/neutron (new) Muon dual-solenoid geometry (new), with ATLAS drift tubes. Design philosophy:

29 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.

30 Brian Foster - Cosener's Forum May European GDE 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.

31 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 directors 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.

32 Brian Foster - Cosener's Forum May European GDE 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.

33 Brian Foster - Cosener's Forum May European GDE EGDE directors 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 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.
