  1. ILC R&D and SCRF • Now in international R&D phase (baseline design defined); validate technology, engineering design, cost. • Current R&D expenditures equal in Asia, Europe, US. • ILC project requires LHC science validation, government agreement on cost share, site, organization. Aim FY2012 start. • Major benefit from R&D phase – SC RF technology

  2. SCRF opens opportunities Development of SCRF for HEP finds broad application in many sciences. In addition to these US facilities, SCRF accelerators exist in Canada, Switzerland, England, France, Italy, Germany, Japan, Taiwan, China, Korea, India, Australia, … SCRF enables: High energy accelerators Neutrino sources Nuclear structure Heavy ions Light sources Energy recovery linacs Free electron lasers Neutron sources Photoinjectors Transmute nuclear waste

  3. SC RF Infrastructure Weld free cavity forming Chemical / electropolish Rinse, bake Intensive R&D; extensive test facilities Electropolish Chemical Polish DESY photos String test Vertical / horizontal test Cryomodule assembly

  4. High Gradient Superconducting rf acceleration – the key ILC technology US lags Europe and Japan in developing high gradienet superconducting rf technology. With ~20,000 SCRF cavities in ILC, it is probable that all three regions must contribute. Hosting ILC requires SCRF industrial and testing capability in the US. Where we are now ( FNAL Meson Lab) DESY Tesla Test Facility: Cost was >$150M (~FY1995), SWF not included. Current estimate for 6 year cost of SCRF infrastructure and industrial procurement of cavities and cryomodules is ~$300M

  5. FY2008 plan ($75M ILC + $47M SCRF) • ILC component R&D (~$37M) • SCRF infrastructure (~$25M) • Industrial SC component procurement (~$22M • Engineering design (largely manpower) (~$12M) • Detector R&D (~$20M) • Site evaluation (~$4M) • Management (~2M)

  7. FALC • FALC = Funding Agencies Linear Collider (US DOE, US NSF, Canada, Germany, France, UK, Italy, CERN (smaller EU nations), Japan, S. Korea (India, China, Russia to be added?) • Established common fund for GDE. • International review of Reference Design cost estimate (2007) • Document technological benefits of ILC for governments/industry • Coordinate planning of large world projects (ILC, LHC upgrade, intense n sources, CLIC R&D) • TO DO: • Establish procedure and time table for site proposals, evaluations (needed to complete TDR). • Formalize oversight and organization structure of GDE

  8. International discussions China - visit 6/06 – “will join ILC” S. Korea - first ILC funding 2006 Europe - LHC priority. CERN Council: “‘fundamental to complement LHC with ILC.” Canada: minimal now, but interest Russia - waiting to complete LHC commitment US – NAS panel: “US should launch major ILC R&D” Japan: Diet Federation: “support realization of ILC” India - visit 10/06 discuss partnering with US on SCRF

  11. I think Robin wanted something like this; can simplify as desired. EPP2010 Report“The US should launch a major† program of R&D, design, industrialization, and management and financing studies of the ILC accelerator and detectors.” (as the highest priority future effort. CERN Council European strategy for particle physics (2006):“It is fundamental* to complement the results of the LHC with measurements at a linear collider.” “The first general meeting of the [Japanese] Federation of Diet members to promote the realisation of ILC … As an important international project in the fundamental sciences, the Federation decided to give strong support toward the realisation of the ILC.” (ILC News, 6-22-06) †EPP2010 identified R&D costs as $500M over FY2007 -- 2011. Adding FY2006 actual and FY2012 estimate, detector R&D, SCRF infrastructure raises this to $820M. *CERN strategy group lexicon:

  12. International discussions China: Staffin/Minister of Science and Technology in June 2006: “we will join the ILC”; discussing R&D involvement at $10M level India: Staffin/Minister of Science and Technology in October 2006: Indian partnership with US in SCRF at $10M level? So. Korea: first ILC specific funds allocated in 2006 Japan: Formation of Federation of Diet members for realizing the ILC (Sugawara), with statement of intent to propose ILC in Japan. Priority of JPARC had prevented official discussion of ILC in Japan; now MEXT expresses its desire to pursue ILC. First infusion of significant funds for detector R&D (JSPS). Russia: Funding constraints, difficulty in securing the Russian contribution to LHC hinders formal ILC role, but the accelerator expertise helps ILC R&D. Canada: minimal involvement, but growing.

  13. International discussions Europe: Situation in Europe is complex. (Orbach visit in August 2006.) Top priority is LHC, with LHC upgrade prominent in many nations priorities. CERN Council Strategy Group rated ILC as “fundamental”. Council is emerging as primary European strategic planning group. CERN continues to pursue CLIC R&D as potential future project; expert evaluation sees CLIC as being beyond the horizon of next decade. Germany is leading the XFEL construction project. France is most aligned to CERN future plans. UK is contributing large funding to ILC, with focus on beam delivery system, detector R&D. Tension between CERN and US over operating costs, LHC upgrades will tend to limit European funding for ILC in US.

  14. GDE FY2007 plans (ok for backup) • Complete Reference Design, cost estimate. Aim for international review under FALC oversight (Lehman from US). • R&D on critical baseline elements and alternates holding promise for cost saving or improvement in reliability. • Restructure the GDE to begin the Technical (engineering) Design activities. • Develop world R&D plan. At present 4 planning task forces: • cavities and cryomodule • string tests • damping rings • final focus/beam delivery)

  15. Superconducting rf acceleration – the key to future accelerators Past investment by HEP in SCRF has led to current facilities CEBAF and SNS. The future of light sources (for material science, environmental studies, structural biology), energy recovery linacs, rare isotope accelerators, heavy ion research, and intense neutrino beams depends on expanding the capability of SCRF. Shorter high gradient linacs should provide spin-offs for medical and industrial applications (e.g. neutron therapy) In the near term high gradient SCRF relies on the ILC R&D program. The chief broader benefit of the ILC R&D program is acquisition of the SCRF technology. HEP has enabled past advances in other fields: the SPPS and LCLS at SLAC for short time resolution imaging, structural biology, plasma studies, chemical kinetics are dependent on the investment and experience at the SLAC linac.

  16. Superconducting rf acceleration – the key to future accelerators DOE/OHEP has recognized the generic importance of SCRF R&D and infrastructure and will define a budget category for it in FY 2007. Budget $23M (if FY2007 appropriation is at $60M). The FY2008 over target request of $47M for SCRF infrastructure and industrial partnership is essential for advancing ILC R&D, and for establishing the basis for future SC facilities. Without such infrastructure and industrial capability, the advanced DOE/SC accelerator facilities will not be possible. Developing high yield, cost-effective and reproducible SC cavities is the highest priority for the ILC R&D program worldwide.

  17. SC RF Effort Coordinating role at Fermilab, with infrastructure development for cavity, cryomodule and string tests. ANL: High volume facility for surface preparation using buffered chemical polishing and electropolishing. TJNAF: Development of new materials and maintain modest volume capability for cavity fabrication and electropolishing. LANL: test stand for single cavities SLAC/LLNL: develop high power rf power systems Universities* (Cornell, Michigan State, William&Mary, Old Dominion, Wisconsin, Northwestern): modest surface preparation facilities, develop new electropolishing techniques, new cavity fabrication techniques, materials research. * DOE and NSF support

  18. US FY2007 plans (assuming $60M) • ~$120M in work package requests for R&D and engineering design from labs and universities, prioritized to fit $60M budget. • Top R&D priority is getting reliable 35 MV/m cavities and infrastructure needed to refine process and test prototypes. • By end 2006, complete a 3 year R&D plan for US R&D: goals, resource needs, milestones, deliverables. (Must be iterated with GDE guidance on worldwide plans) • Detector R&D multiyear plan with goals, milestones, resource needs. * Generic R&D examples: high availability power supplies, beam simulations, laser development, high power rf sources, SCRF materials research … .

  19. Deployment of FY2007 Labs effort FNAL (47%): SCRF cavity, cryomodule; SCRF test infrastructure; beam optics; civil construction; outreach; magnet design. SLAC (37%): rf power sources and tests; rf distribution; high availabilty power supplies; controls; electron/positron sources; damping ring optics; bunch compressor; beam alignment; wakefield studies; magnet design; electron cloud tests; beam instrumentation. ANL (5%): damping ring design; cavity surface treatment. BNL (3%): final focus magnets. LBNL (3%): damping ring design; positron source; vacuum engineering. LLNL (3%): rf couplers; rf pulse power systems; positron target; beam position monitor. TJNAF (1%): cavity surface treatment, large grain Nb cavity development. LANL (1%): cavity testing.

  20. FY2008 plans ($75M ILC + $47M SCRF) • ILC R&D: Prototype & tests of key components – undulator for photons and positron source target, damping ring collective effects, final focus magnets and optics design, bunch compressor beam elements, ILC cryomodule fabrication, … (~$20M) • Generic R&D also needed for ILC: test high efficiency dc to pulse power modulators, develop and test high efficiency klystrons; test new cost reducing rf power components; test high availabilty power supplies, prototype large grain niobium cavities, … (~$17M) • Engineering design (largely manpower) (~$12M) • Sum of ILC R&D and design (items 1 -3) : $49M

  21. FY2008 plans ($75M ILC + $47M SCRF) • Detector R&D: prototype energy flow calorimeters and test beam studies, development of pixel detector electronics with analog energy/time information, develop compact silicon sensors for muon/tracking signal collection, prototype data concentrators and signal multiplexing, integrated detector design, … ($20M). [This would raise the US detector R&D effort to that in Europe.] • Site evaluation: characterization of geological features of candidate sites, preliminary environmental assessment, impact of local land use, … ($4M) • Management: GDE common fund, salaries of top management; US communicator and public outreach … ($2M)

  22. FY2008 plans ($75M ILC + $47M SCRF) • SCRF infrastructure: facilities for electropolishing, chemical polishing of Nb surfaces, electron beam welding stations, horizontal test stands for fully dressed cavities for high power tests (with cryogenic, rf, intrumentation infrastructure), cryomodule test stand (1 cryomodule = 8 cavities), facilities for string tests of rf units with beam (1 rf unit = 3 cryomodules, one quadrupole, powered by one klystron), … ($25M) • Industrial SCRF procurements: SCRF cavities for testing process steps & installation in test cryomodules, rf couplers, rf power components (klystrons, modulators, distribution), cryomodules, … ($22M) • Total SCRF infrastructure and R&D (items 7,8) ($47M) • With over target budget for SCRF infrastructure and ILC R&D, will be able to prepare cryomodule and string tests during FY 2008 – 2010, on timeline to match efforts in Europe and Japan and enable consideration of ILC project.

  23. Out year projections The R&D phase of ILC R&D should follow a profile similar to that of a construction project. The synergy with SCRF activity is important to ILC as well as serving the broader DOE SC program. EPP2010 estimate (adding infrastructure, detector R&D not included) is a five-year integral of $820M. Without the SCRF effort the profile fails to meet the need to validate the ILC design or put the US in a position to make a credible bid to host.
