After ISS

1. After ISS Where Do We Go From Here?

2. Next - until the end of 2006 • Produce the ISS Report • - with the present team & structure • A Good Report is Vital • it will provide the basis of bids for R&D funding for the next stage, assuming there is a community to support it • Devise a New Effort to carry the Work Forward • But what is the best way? P Dornan - After ISS

3. The ISS Report for the Neutrino Factory • It must address • Ourselves • We have to be convinced it is viable and will produce good physics • The wider n community • Main problem here is probably timescale • The wider particle physics community • Many in he LHC – ILC communities consider n-oscillation is just a blip on the SM and that ‘serious’ BSM physics will only come from the quark sector • The funding agencies • Requires pressure from the PP community • The Labs • n-factory has to be in possible future plans P Dornan - After ISS

4. Structure for a Continuation • Must be established during the fall • What form should it take? • How to do it? • Who can do it? • Here are some thoughts • From the ISS - PC and the original ‘Wise Men’ • for discussion this week P Dornan - After ISS

5. Goal - An Advanced Neutrino Facility • - for data taking before 2020. • To choose • The facility to produce the very best physics return • But maybe too expensive • The facility giving max physics/$ • Weighting physics return is subjective • Need a compromise • & probably more information e.g. size of q13 • So cannot make such a judgment today • But equally cannot keep postponing it P Dornan - After ISS

6. What would it be? • Neutrino Factory • b-Beam Facility • High power Superbeam and very large detector • Possibly two of these - but not three • Future - how to proceed? • Single Study embracing all three? • Three independent studies? • -assuming all three communities believe it necessary • Three quasi-independent studies but with coordination where practicable and an overall oversight body. P Dornan - After ISS

7. Why An Independent n-Fact Study? • The synergies with the others are not great • Accelerator • After p-driver and target - little in common • Detector • For n-fact – high energy n, magnetised • For Superbeam - low energy n, non-magnetised, very large • For b-beam, non-magntised • Physics • This is in common, provides the overall motivation and is one of the critical discriminators P Dornan - After ISS

9. The Oversight Body • International cooperation for a future advanced neutrino facility has been strongly advocated by • EPP2010 • CERN Council Strategy Document • The four ISS ‘Wise Men’, Steve Geer, Yoshi Kuno,Vittorio Palladino, Ken Peach, have drafted a letter to go to all relevant accelerator lab directors asking them to facilitate coordinated R&D in the neutrino area and establish an • ‘International Neutrino Facility Oversight Committee’ (INFOC) • With copies to spokespeople of all major current neutrino experiments • Aim to finalise the draft this week P Dornan - After ISS

10. INFOC • Representatives of the Labs • And funding agencies? • The Individual Neutrino collaborations would report to INFOC • Would recommend support, funding, engineering for the projects • Monitor Progress • It ultimately would decide on the form of the future neutrino facility P Dornan - After ISS

11. The Neutrino Factory Collaboration • For the Neutrino Factory area there would be an International Neutrino Factory Collaboration (INuFC) • Would focus purely on the n-fact approach to a future n-facility • It would have a structure similar to the ISS • Accelerator group • Detector Group • Physics Group P Dornan - After ISS

12. INuFC - Aim • To produce by ~2010 an interim report outlining • A n-factory solution for a n-facility which could produce data before 2020 • Dependent on a successful outcome of R&D underway, e.g. MICE and other R&D following the ISS • Dependent on the value of q13 • Approximate costs • Site Considerations • Make it possible (with resources) to produce a CDR for a n-fact by ~2012, a TDR by ~2014 and data by 2020 P Dornan - After ISS

13. Ambitious Plan • But it is necessary - in order to • Engage accelerator scientists, engineers, the n-physics community • A device for ~2030 has little attraction at the present time • Have an international n-factory on the particle physic roadmap • And encourage the major labs/regions to include it on their roadmap • And for one of them to ‘host’ the effort • Ensure adequate (substantial) resources for the CDR P Dornan - After ISS

14. INuFC - Questions • Structure • Like ISS - 3 WG’s and a PC of WG leaders and an overall coordinator? • Like a PP experiment - a wide steering group? • How are people chosen? • Mandate • Period of 3 years, 2007 – 2010 • Indefinite • Until n-fact is built or funding ceases • These - and many other questions - will need to be established at a meeting around the start of 2007 to coincide with the ISS report P Dornan - After ISS

15. INuFC - Needs - Goals • Get Resources • Use ISS report for bids to labs, funding agencies, EU etc. • Persuade a lab (or group of labs) to ‘host’ the study and provide some engineering support • Embark upon the R&D recommended for by the ISS report • Continue the unfinished work of the ISS • Convince the wider n-community that this is in the best interests of neutrino physics • Get People • Need more physicists & engineers for whom this is their major activity • Many in the ISS had very limited time • Need committed young people. P Dornan - After ISS

16. Discussion • These are all suggestions • They need to be discussed • Starting now • Continuing in the corridors - and again tomorrow afternoon. • It is important to have a plan with substantial support from the ISS for the NuFact discussion on the last day. P Dornan - After ISS
