3. 27 Apr 2006P J Dornan - ISS3 - RAL Concluding Discussion ISS RAL Meeting Apr 2006 ISS a one year Study –commenced NuFact05 –Ends NuFact06 To Discuss Now –Focus efforts For the Final Report & Presentation at NuFact06 –Plan the Next Step after ISS

4. 27 Apr 2006P J Dornan - ISS3 - RAL The ISS End Game Presentation –At NuFact06 And then it is important that the results are widely distributed Report –Before the end of 2006 –Based on the 3 Working Groups –What should this include?

5. 27 Apr 2006P J Dornan - ISS3 - RAL Physics –The importance of physics –Justification for precision determination of the oscillation parameters to the level of the CKM parameters? –Comparisons of Performance Superbeam,  -Beam, Factory With various scenarios with appropriate detectors at suitable baselines

6. 27 Apr 2006P J Dornan - ISS3 - RAL Physics Report How important – gold, silver, platinum? In the ideal scenario should we measure e  →  e        →  e     Specifically - how important are the tau channels?

7. 27 Apr 2006P J Dornan - ISS3 - RAL Muon Physics & the Factory Intense muon beams are needed for muon physics Could be the place for the next major advance But - is a Factory suitable for muon experiments?

8. 27 Apr 2006P J Dornan - ISS3 - RAL Detectors Which can effectively be magnetised? Iron calorimeter, Emulsion Liquid Argon?? How low can one reduce the threshold? Which can identify taus? This must tie in with the relevance of gold, silver platinum Cost? Define the necessary R&D Programme

9. 27 Apr 2006P J Dornan - ISS3 - RAL Accelerator This will concentrate on the neutrino factory A viable baseline design with realistic parameters and an indication of increase or decrease in performance as one moves from the baseline Cost & Timescale Cost will not be easy - but even to €0.5B Timescale – Important to show that we could have a precision neutrino facility by tne end of the next decade The R&D Programme - MICE, MERIT, + …

10. 27 Apr 2006P J Dornan - ISS3 - RAL SuperBeams, Synergies Little discussion on future Superbeams Is it assumed problems are understood? Most synergies centre around the proton driver and it is appreciated that the proton driver used will have more than one application - but the effort has been to understand the needs of the neutrino factory.

11. 27 Apr 2006P J Dornan - ISS3 - RAL Incremental Path to a Neutrino  Factory Era of sensitivity & precision Factory  Beam But Factory and  beam can be on same timescale as superbeam upgrades Path to a Neutrino  Factory or  -Beam

12. 27 Apr 2006P J Dornan - ISS3 - RAL After ISS For the precision era –Superbeams,  -beams, -Factory will compete for resources –Could have 0, 1 or 2 Superbeams – plus a  -beam or -Factory complex Decision Point –2009-2011 –Need a CDR for future neutrino complex by ~2009 –  -Beam and -Factory –Assume superbeam developments will come from present proponents

13. 27 Apr 2006P J Dornan - ISS3 - RAL Neutrino Factory Following ISS there needs to be a Design Study for a Neutrino Factory –It will need engineering effort –And therefore resources –Where can these come from? Funding Agencies, Labs, EU –At the BENE/ISS meeting tomorrow planning for a request to the EU FP7 programme will start But funding from this source will not come until mid-end 2007 –Activity must start before then - it should start this year And maintain the momentum of the ISS study

14. 27 Apr 2006P J Dornan - ISS3 - RAL Organisation of the -Fact Design Study –Should be decided by NuFact06 Do we keep a similar structure to the ISS? –Accelerator –Detector –Physics How to get organised? Can we continue to have it truly international?

15. 27 Apr 2006P J Dornan - ISS3 - RAL Coherence of the Neutrino Community Highly Desirable –Can a -Factory IDS be incorporated with the broader neutrino community Superbeams  -Beam –  -Beam also requires a major R&D effort Can these both be conducted under the same umbrella We have to convince the wider community that the precision age (  -Beam or -Factory) is feasible and possible by ~2020
