  2. Overview Introduction Neutrino Factory design in the UK - proton driver - muon frontend - muon acceleration  WP1 World context - World Design Study - FP6 Design Study  WP4 Summary of bid Conclusions

  3. UK Neutrino Factory Design Must complete UK design: - comparable to others - part of Design Studies Mainly theory, but also R&D  WP1

  4. UK Neutrino Factory Design Must complete UK design: - comparable to others - part of Design Studies Mainly theory, but also R&D  WP1

  5. Proton Driver Much theoretical work already done Concentration on detailed studies now, esp. synchrotrons - detailed simulation of synchrotron options - injection foil development - electron cloud instabilities - nanosecond bunch compression - accelerating cavity R&D Aims:  single conceptual design after 3 years  detailed engineering & prototyping yrs 4-6

  6. Reverse Rotation Chicane – no cooling! Muon Frontend – Simulation Two frontends considered so far…….. • more detailed simulation • technical design, particularly of magnets • prototyping of magnets • studies with cooling channels/rings

  7. Main advantages: shorter longitudinal cooling Muon Frontend – Simulation Two frontends considered so far…….. Cooling ring • needs detailed simulation, particularly cooling codes • technical design • prototyping of magnet technology, particularly kicker • R&D on cooling channel components……..

  8. Cooling Cell R&D R&D proposed on focus coil unit……particularly for rings Two important problems of LH2 in rings - heat load: ~600W linear  6 – 12kW in ring! - wedge shape

  9. Cooling Cell R&D Addressed in two ways Development of LH2 absorbers - engineering studies of heat transfer - FEA studies of wedge absorbers - (longer term) prototyping of wedge absorbers Development of alternative absorbers • investigate the use of HTS magnets - study performance of cooling channel with 10-15T - build small HTS magnet prototype - (longer term) full scale prototype

  10. Muon Acceleration and Storage Ring Little study in the UK so far Assess different options for acceleration Simulation and analysis Overall cost optimisation (Longer term) more detailed simulations Storage ring is a neglected item! Also needs careful design and analysis Two target underground laboratories Physics input needed!

  11. WP1 Costs Summary of costs for WP1…….

  12. World Design Study Initiated at NuFact’03 Follows on from: 2 FS in US (2000 & 2001) 1 DS in Japan (2002) Steering group created: US: Steve Geer (FNAL) Bob Palmer (BNL)Mike Zisman (LBL) Japan: Yoshi Kuno (Osaka) Yoshi Mori (KEK) Kenzo Nakamura (KEK) Europe: Alain Blondel (Geneva) Rob Edgecock (RAL – chair) Helmut Haseroth (CERN) Define scope and timescale: - years 1-3: investigate options - years 4-5: detailed engineering  WP1-3 all part of study

  13. Host Laboratory In addition: host laboratory could be RAL! UK would take centre stage in World R&D Huge opportunity for the UK! Must be able to call on local resources for support on - infrastructure - safety - facilities - geology - etc - proton driver WP4 Must also demonstrate significant commitment to WDS  WP1 to 3 Main/only competition: J-PARC

  14. FP6 EC Framework 6 Programme Already some success as part of CARE: - BENE NA: 30% (0.4M€) - HIPPI JRA: 90% (3.6M€) Much more important: Design Study (10M€) Call for proposals November; deadline March-April Basis of EU contribution to WDS: - part-fund EU contributions- fill funding holes, e.g. MICE, FFAGs Needs host laboratory  RAL obvious candidate Will need administrative support from RAL Requires matching funding

  15. WP4 Costs £352.7k £1.0M

  16. Summary of Proposal Programme of activities developed: - build on our achievements so far - takes us a long way towards our ultimate goal  Neutrino Factory in the UK After 6 years……. + world Neutrino Factory leadership + conceptual/engineering Neutrino Factory design at RAL + operating proton driver frontend + design for a 4MW target + demonstration of cooling with MICE + completed programme of R&D on cooling components

  17. Conclusions The UK has a huge opportunity! - take the lead in a large accelerator project for PP - take a significant step in our ultimate aim UK has achieved a lot in the last 4.5 years It is essential to build on this Must be done now! - WDS: starting now - EU FP6: proposal next spring, matching funding - Advances elsewhere: in particular Japan A coherent programme of R&D is proposed that does this This has been done within the world context
