Networking Activity on Beams for European Neutrino Experiments BENE-Next ….. MEGLIO?

1. First ideas for the proposal within the “CARE-Next” of a Networking Activity on Beams for European Neutrino Experiments BENE-Next ….. MEGLIO? • Motivation • Work Packages • Partners & resources deputy coordinator (accelerators physics): M. Meddahi/CERN deputy coordinator (particle physics): S. Pascoli/Durham coordinator: V. Palladino/INFN-NA

2. “BENE-Next” interests across “CARE-Next”

3. NuMI CNGS JPARCʋ Wider view of “BENE-Next” interests Existing Facilities MuCool, MTA MCTF R&D US FP7 CARENext R&D EU R&D BENE Next R&D Asia HARP, HIPPI, MICE, MERIT, EMMA …..

4. How far will BENE get? main result so far : recognition by Council Strategy Document mid 2006 BENE integrates and co-ordinates the activities of the accelerator and particle physics communities working together, in a worldwide context, dedicated to the study of a forefront neutrino beam facility for Europe. The final objectives are• to establish a road map for upgrade of our present facility & design and construction of a new one;• to assemble a community capable of sustaining the technical realization and scientific exploitation of these facilities;• to establish and propose the necessary R&D efforts to achieve these goal. A final report is due in December 2008. rich landscape of multiple international projects, no final statement mature yet, nor necessary more work essential , harmonize further legitimate national interests excellent record: HARP, MICE, MERIT, FP6Beta Beam, ISS FP7EuroNeutrino, ISS&IDS, JRAs? more? FR2008 will be there, but time scale is really 2012, rather

5. Motivation of BENE-Next • for EU to keep a leading accelerator neutrino program • in line with CERN Council Strategy Document • to improve EU infrastructure of neutrino accelerator sources • ie CNGS, latest & most intense • in 40 years or so at CERN • by conventional(M)MW upgrade • (Superbeam: CNGS+ …. ) • or novel approach upgrade • (Betabeam or ʋ-Factory) • while international context grows richer • NuMI up & running, soon JPARCʋ • R&D & DS increasing for novel and stronger νbeams • an FP7 Networking Activity is felt crucial • to pursue & enhance integration & coherence of all initiatives • to assess & disseminate the knowledge • continuing BENE line of successes • (last EUROʋ Design Study • of the three leading options above) • with main deliverable its 2012 road map Final Scientific Report • one year after completion of EUROν • most likely time for new EU HEP initiatives

6. Resulting objectives • Improving our EU accelerator complex for ʋ physics • demands to • Link & assess the experience of neutrino facilities, either operating – in construction- or study (Euroʋ) • Perform the communication among the various R&D initiatives, both in the IA and in the wider community. • Foster intellectual excellence, offer space to new ideas • ensure the dissemination. • Consolidate the community that will be sustaining these facilities. • cherish and promote consensus! • Contribute, to the optimal EU road map towards both improved and new accelerator neutrino facilities.

7. Work Packages • WP1: Management of the network • WP2: Accelerator Neutrino R&D (subsystems) • . • WP3: Accelerator Neutrino Facilities (end-to-end) • WP4: Physics reach

8. WP1: Management & Coordination • Tasks • overall guidelines • contractual, financial and administrative aspects • use, dissemination and protection of the knowledge • Deliverables: • Web Sites of the NA and WPs • Yearly, 1 to 2 NA + 1 NF (the established International NuFact) Workshop. • Proceedings and/or Web Sites.New R&D Proposals, if they prove necessary • Mid-term Sctientific Report after 2 years • Final “road map” Scientific Report

9. WP2: Accelerator ʋ R&D (sub-systems) covers FP7 activities & related worldwide efforts (candidate WP Leader tbc) • Assessment & dissemination tasks for R&D on subsystems : • High power proton injectors [M. Zito/CEA] • Multi MW target and collectors [C. Densham/RAL/M. Dracos/IN2P3] • High field magnets [TaskLeader tbd] • RF techniques R. Seviour, Daresbury • Ionisation cooling [[TaskLeader tbd] • Radioactive ions technologies [TaskLeader tbd] • Acceleration & storage (FFAG & more) [TaskLeader tbd] • Communication: IA, NA and WP Workshops • Deliverables: communication with all activities, assessments of the interests of the findings of the IAs for neutrino facilities and foresight of studies towards new technologies, summarised in Workshops Proceedings, Mid-term and Final reports. 9

10. WP3: Accelerator ʋ Facilities (end-to-end) Assess & disseminate “end-to-end” knowledge and experience (candidate WP Leader tbc) • 1 Performance of CNGS and its upgrades [candidate TL tbc] • 2 EUROʋ & other international DS [candidate TL tbc] • Communication: • WP workshops within NA workshops or as necessary, in phase with other European and international partners. • Deliverables: • WP Workshops with web sites or proceedings. Link and summary of main findings in Mid-term and Final Reports.

11. WP4: Physics Reach (A. Donini/UAMadrid, M. Mezzetto/INFN-PD) • NB Preliminary formulation, to be finalized by WP convenors and physics deputy. • The physics connection remains decisive in the neutrino sector, • as it is for BENE. Objectives will be • raising wide awareness of the main experimental, phenomenological and theoretical progresses • bringing about a consensual evaluation of the physics reach of existing and of currently proposed arrangements of neutrino beam & detector type. • Physics and phenomenology connection [task lead tbd] • Experimentation at CNGS and its upgrades [task lead tbd] • Experimentation at Euroʋ facilities [task lead tbd] • Experimentation at other international facilities [task lead tbd] • Communication: • WP workshops within NA workshops or as necessary, in phase with other European and international partners. • Deliverables: • WP Workshops with web sites or proceedings. Link and summary of main findings in Mid-term and Final Reports. Possible task leaders Thomas Schwetz, Olga Mena, F. Terranova, G. DeLellis, F. Sanchez, A. Cervera, JJ Gomez, S. King and certainly many more. Main players in the IDS Patrick Huber, Pilar Hernandez, Walter Winter should be consulted regularly

12. Partners and resources kernel: 13 nodes in BENE • All most important EU Labs/Agencies • INFN, CERN, CCLRC, CEA, IN2P3, IFIC, • PSI, GSI, Julich • and a few consortia of universities in • Belgium, CH, UK, Germany, • (in addition to those around INFN, IN2P3, IFIC) • renewing or establishing partnerships now

13. Partners and resources: tentative! good value expected 15 nodes ! almost all grouping several labs participation is vital networking resources across the full CARE-Next initiative (WG1/2/3) keep a large and representative forum active assembling a community, attracting newcomers, fostering consensus

14. A highly preliminary 4 years plan
