Presentation Transcript

  1. The International Linear Collider Project Akiya Miyamoto KEK Do Son ACGRID School Symposium

  2. Particle Accelerators and Colliders Explore micro-world • CERN/LHC • p-p collider, 14 TeV • Radius ~ 9km 1932 Lowlence’s cyclotron : 80 keV p-p collider Do Son ACGRID School Symposium

  3. International Linear Collider : ILC e+e- Collider Ecm: 0.2 ~0.5 TeV  1TeV ∫Ldt = 500 fb-1 in 4 years Do Son ACGRID School Symposium

  4. Why e+e- collider ? Collisions of elementary particles p p • Uses all energy for collisions • Clean measurements • Sensitive to faint signals of new particles/phenomena • State-of-the-art detector e+ e– Well known initial state • Initial 4 vectors and polarizationsare known and controllable • Precise tests of theory Do Son ACGRID School Symposium

  5. Progress of e+e– colliders Linear Collider Circular collider J/ Do Son ACGRID School Symposium

  6. Tera Scale: EW symmetry breaking • Standard Model LEP WG 2006 g W t u c g G b s d H t m e nm ne nt Theoretical Higgs mass bound ILC reach Do Son ACGRID School Symposium

  7. Higgs – Vacuum Did Higgs break the symmetry ? Condensed in vacuum ? Higgs coupling proportional to mass in the SM Do Son ACGRID School Symposium

  8. Supersymmetry Extending to Higher energy/Early Universe Fermion  Boson • Do forces unify ? • Do Quarks and Leptons unify ? Do Son ACGRID School Symposium

  9. Cosmology and ILC Do Son ACGRID School Symposium

  10. Extra Dimention Brane world ? - graviton may live in bulk Linear collider G extra dim. (bulk) e– g e+ our world (4D) Number of Extra Dimension Do Son ACGRID School Symposium

  11. Precision Physics ILC ACFA WG Top mass: Dmt < 100MeV( 1/10 better than LHC ) Top couplings Do Son ACGRID School Symposium

  12. ILC, ILCSC, GDE The ILC project was initiated in 2004 with the endorsement by ICFA and ILCSC GDE was formed to develop the ILC accelerator design. Do Son ACGRID School Symposium

  13. High Gradient Acceleration Towards 31.5 MeV/m 3 types of cavity shapes under study 10MW L band klystron 9 cell cavity ~ 1m long A test cryomodule in preparation at FNAL Similar tests in progress in Japan, China, Korea, India and world wide 1 Cell RE cavity: > 50 MeV/m Do Son ACGRID School Symposium

  14. High Luminosity • Low emittance machine optics • Contain emittance growth • Squeeze the beam as small as possible KEK, ATF since 1993 Test bench for ILC-DR e- e+ ~ 5 nm ATF2 line Do Son ACGRID School Symposium

  15. ILC Facility Particle detector ~31km tunnel Research Area Dumping Ring Two tunnels for Accelrator and service Do Son ACGRID School Symposium

  16. ILC Reference Design Report Released 2007 summer: http://www.linearcollider.org/cms/?pid=1000437 RDR: 4 volumes/ 774 pages Executive Summary Physics at the ILC Accelerator Detectors Do Son ACGRID School Symposium

  17. RDR Authors Connected through Internet North America Asia Europe ~325 institutes ~1800 authors

  18. GDE plan and Schedule Next milestore Do Son ACGRID School Symposium

  19. Detector Roadmap • Detector time line should be synchronized with accelerator time line • because detector construction time would be similar to accelerator construction time • 2010: ‘light’ two detector EDRs • To be ready together with the accelerator EDR • Not for construction • Cost accuracy consistent with that for accelerator • 2008: Select two groups to write EDRs based on LOIs. • October 4, 2007: • ILCSC announces call for LOIs, due 1 October 2008. Do Son ACGRID School Symposium

  24. GRID for ILC Why GRID ? • A large CPU and storage resources for detector optimizations and physics performance studies • Share CPU/storage/human resources for studies in a global framework Two VOs, ILC and CALICE, are in place • ILC VO • a global VO of EGEE • a number of GRID sites world wide support ILC • CALICE VO • CALICE is an international collaboration for calorimeter R&D( ~ 200 phys.&eng. / 29 labs./12 countries in Asia/EU/NA • Test beam data (~14TB) is maintained and heavily used. Do Son ACGRID School Symposium

  25. Conclusion ILC is crucial to push forward our understanding of fundamental low of nature. Research and Developments for accelerators and detectors for ILC are extensively pursued world wide. GRID is the indispensable elements of ILC studies. Do Son ACGRID School Symposium
