  1. Accelerator R & D Outline: Why now ? What ? How ? 1

  2. Why now ? Because of the need to prepare for: • continuation after ISS (deadline: NuFact06 in August) • continuation after CARE. + It has to fit inside the future European Strategy as outlined by the CCSG and as supported by the CERN council (to be known at the latest in October 2006). 2

  3. What ? Proton drivers: • Linac-based solutions: high energy part (superconducting cavities, high power RF, beam dynamics,…) • RCS-based solutions: no request (mature) • FFAG-based solutions: not mature (could be part of generic R & D on FFAGs) 3

  4. What ? Targets: • Liquid jet: MERIT experiment results mid-2007 • Solid: investigations started. To be pursued. • Flowing liquid: remains to be defined 4

  5. From R. Bennett 5

  6. What ? Muons collection: • Solenoid: not foreseen in EU yet • Horns (super-beam): horn & power-supply Preliminary schedule ( M. Dracos) • Design of Power Supply: 2006-2007 • R&D, tests and simulations, feasibility: 2006-2008 • new horn prototype: 2009 6

  7. What ? Muons Front End (K. Long): • MICE Phase II • Contribution to concept development of Geer’s scheme: • Development of front end (phase-rotation, bunching, cooling scheme etc.) in context of end-to-end design • Technological developments for normal conducting/high gradient cavities (in high B field), sc magnets, RF power sources… • Investigation of “novel” cooling schemes [helical cooler, cooling in a ring (FFAG ?), …] 7

  8. What ? Muons Acceleration and storage (F. Meot): • Need for major effort on beam dynamics. • Acceleration: numerous schemes available (FFAGs, RLA) & no obvious “winner” today => need for technological developments (Superconducting RF & high power RF hardware, study of FFAGs potential…) + comparisons • Storage: 2 possibilities (racetrack or triangle) => technological developments (magnets, RF, kickers,…) 8

  9. How ? Numerous proposals submitted to ESGARD. Unlikely to be integrated in a single I3 (R. Edgecock). Look for synergy with other teams (FFAGs with industry and medicine, sc RF with ILC, Target and radioprotection with IFMIF/EURISOL/n spallation sources…) However, need for a coordinating body. 9
