ISS After One Year Peter Dornan Imperial College London

21 August 2006P Dornan - ISS after One Year2 A Little History  NuFact03  2004  April 2005  May 2005 Plan for a World Design Study towards a future Neutrino Factory - failed to get support Plan for a proposal to 2 nd call in EU FP6 design study programme - 2 nd call cancelled John Wood – CEO CCLRC(RAL) – requests a ‘Scoping Study’ for a future neutrino factory – and promises support Meeting in London to start the process (~40 people came at short notice) Committee – S Geer, Y Kuno, V Palladino, K Peach charged with setting up the organisation

21 August 2006P Dornan - ISS after One Year3 Why an ISS? From the Physics Community  The importance of Neutrino Physics  Belief that ultimate measurements will require a new type of facility From the Labs And in particular RAL in the UK  The need to plan for the future A number of large projects are being considered  Should a Neutrino Factory feature in this exercise?

21 August 2006P Dornan - ISS after One Year4 The RAL situation  RAL (Rutherford Appleton Lab) part of CCLRC  Used to be a PP accelerator lab  More recently has concentrated on neutrons, lasers, light source  But MICE has put PP accelerator activities back on the map  RAL management – with support from the UK government - wish to host a large future international project and are now examining possibilities  A neutrino factory is a possibility

21 August 2006P Dornan - ISS after One Year5 The ISS  Following the London meeting the ISS was launched at NuFact05 in Frascati  The brief was broadened to include future superbeams in addition to the neutrino factory But not beta beams – covered by the Eurisol project  The study became truly international Support from NFMCC in the US, Nufact-J in Japan, BENE in Europe Equal sharing of positions between Europe, Japan and the USA Meetings take place in all three areas  Results to be relevant for the whole community not just one lab.

21 August 2006P Dornan - ISS after One Year6 The Precision Era - after T2K and Nova Around 2012 We shall have good measurements of   12,  23,  m 2 12,  m 2 23 Probably have a measurement of  13 Possibly know the mass hierarchy So can plan for the ultimate neutrino measurements  Refine all parameters  Check consistency  Measure CP Violation This is the aim of the ISS

21 August 2006P Dornan - ISS after One Year7 CP Violation

21 August 2006P Dornan - ISS after One Year8 Neutrino source – options: Second generation super-beam  CERN, FNAL, BNL, J-PARC II Beta-beam Neutrino Factory

21 August 2006P Dornan - ISS after One Year9 ISS: organisation

21 August 2006P Dornan - ISS after One Year10 Meetings Plenary meetings to date:  CERN: 22 – 24 September 2005 Attendance: 90  KEK: 23 – 26 January 2006 Attendance: 70  RAL: 24 – 29 April 2006 Attendance: 80  Irvine: 21 – 23 August 2006 Attendance: 70 Working groups:  Physics: Workshops:Imperial: 14 – 21 November 2005 Boston: 6 – 10 March 2006 Valencia: 3 – 6 July 2006  Accelerator: Workshops:BNL:07 – 12 December 2005 Princeton:26 – 28 July 2006  Detector: WorkshopsCERN:3 – 5 July 2006 Detector/Physics parallel at Physics workshops

21 August 2006P Dornan - ISS after One Year11 ISS: motivation Goal: timely completion of conceptual design  Significant international effort taking several years Requires successful bids to provide the resources Preparation for design study  Review physics case  Critical comparison of options  Review options for accelerator complex: Prepare concept-development and hardware-R&D roadmaps for design-study phase  Review options for neutrino-detection systems Emphasis: identify concept-development and hardware-R&D roadmaps for design-study phase  Establish the Cost Drivers & Optimize Physics/$ - where there are alternatives Absolute scientific value - where only one method

21 August 2006P Dornan - ISS after One Year12 Where have things gone well  It has brought together a substantial part of the neutrino community to seriously consider how to plan the future  It has been a truly international effort  It has put a future neutrino facility on the road map as a future international project EPP2010, CERN Council Strategy Document  It has emphasised the need to consider the accelerator and detector together - and also the physics goals  The stage is set now for a detailed design study leading to a CDR But it needs resources

21 August 2006P Dornan - ISS after One Year13 Where have things gone less well  The problems associated with high power superbeams have not been covered in detail  A significant part of the neutrino community still consider anything but an increased power superbeam to be far in the future - and therefore irrelevant today This does not encourage lab directors and funding agencies to provide R&D funds now  There has been no serious engineering activity - either for costing or R&D

21 August 2006P Dornan - ISS after One Year14 The Immediate Future i.e. under the present ISS structure This meeting NUFACT06 The ISS Final Report

21 August 2006P Dornan - ISS after One Year15 This Meeting Essentially a wrap-up meeting for the one year ISS study Decide what to present at NUFACT Decide what should be included in the final report  The final report will be critical for obtaining resources for future activity
