Presentation Transcript

  1. EURO A High Intensity Neutrino Oscillation Facility in Europe • Introduction • What EUROnu is doing • Next step • Input to the Strategy Review • Future of EUROnu • Conclusions On behalf of the EUROnu Consortium

  2. EUROnu • FP7 Design Study • Due to limited funds: focus on possible “next” generation neutrino oscillation facilities in Europe • Do: • Conceptual designs of accelerators • Performance of baseline detectors • Physics performance • Approximate costs • Project started: 1st September 2008 • Duration: 4 years – completion in August 2012 → Almost finished & much work done → Ideal timing for Strategy Review

  3. EUROnu Work • Three facilities • CERN to Frejus Superbeam: • Based on 4 MW SPL • Targets, horns, integration and target station • Beam preparation for targets • Performance • MEMPHYS detector at Frejus • Much of the work is generic Marcos Dracos, Marco Zito, et al

  4. Super-Beam

  5. Super-Beam To minimise extrapolation from working facilities: 4 targets and horns

  8. Neutrino Factory • Close collaboration with IDS-NF • EUROnu: target to muon acceleration • Aim: Reference Design Report • Detectors: MIND + near detector(s) • Baseline redefined following θ13: 10 GeV instead of 25 GeV • cheaper • easier to build Juergen Pozimski, Ken Long, et al

  9. Neutrino Factory Towards a Low Energy Neutrino Factory LENF

  12. Beta-Beam • Main issue in EUROnu: maximise ion flux in SR • Studied: • new ion species • alternative production methods • collective effects • collection • bunching • acceleration • storage • 2 ion options considered: - 6He & 18Ne → from EURISOL- 8Li & 8B →fromC. Rubbia et al Elena Wildner, et al

  13. Beta-Beam CERN Specific, Beta Beam favored by q13 results Decay Ring: Br~ 500 Tm, B = ~7 T, C = ~6900 m, Lss= ~2500 m, g = 100, all ions

  14. Beta-Beam 6Li (3He,n) 8B Collection device tests INFN, Legnaro ECR source tests Experiment on direct production of 18Ne at ISOLDE

  15. Limited funding: only performance and cost • Concentrate on baseline detectors • Magnetised Iron Neutrino Detector - NF • Large water cherenkov – SB and BB • Near detectors • Extrapolations from existing technology, not new Detectors Paul Soler, Anselmo Cervera, et al

  16. Physics performance determination • Done independently of facilities, as it should be • As far as possible • everything done in a consistent manner • including systematics • migration matrices • First comparison from Enrique Fernandez-Martinez & Pilar Coloma Physics Pilar Hernandez, Andrea Donini, et al

  17. Physics • LENF: 1.4x1021 decays per year, 100 kt mass MIND at 2000 km • BB100: gamma=100, with 1.3/3.5x1018 decays for Ne/He, 10-2 • atmospheric background suppression, 500 kt WC detector • SPL: 4 MW proton driver, 500 kt WC detector • CN2GS: 0.8 MW, 500 kt WC detector at GS (730 km) • CN2PY: 0.8 MW,100 kt LAr at 2300 km • 10 years total running • 5%/10% systematics for signal/backgrd

  18. Physics

  19. Costing • Doing the best we can with limited resources • Using CERN costing tool – developed for CLIC • Using as much existing knowledge as possible • Being done in a consistent manner: - Same assumptions - Same costs, where possible • Using CERN as the location • Civil engineering is a significant component • All facilities have been laid out at CERN Ilias Efthymiopoulos, Elena Wildner, et al

  23. Next Steps • EUROnu finishes in 3.5 months • FP7 final reports are limited • Special EUROnu edition of: Physical Review Special Topics: Accelerators & Beams • Papers: - Introduction - Overview of each facility & detectors - Special papers on specific work • Introduction – EUROnu summary for Strategy Review? • Deadline for Overview papers: 31st July!

  24. Input to Strategy Review • Date of EUROnu annual meeting: 12th-15th June • Fixed and announced about a year ago • First and only opportunity for EUROnu to discuss SR • Fortunately: 6 weeks to submission deadline • EUROnu future: • Aim: proponents of future facilities working together • Has worked well • Would like to continue • Depends to some extent on new CERN Strategy • Appropriate programme in Horizon 2020 (~FP8)

  25. Conclusions • EUROnu has been running for almost 4 years • Much detailed work done • Physics parameters much more reliable and defendable now • What needs to be done after EUROnu is known • Work coming to an end • Main things still to be done: • Complete modifications for large θ13 • Complete costing • Write everything up • Decide on future • It has been a pleasure to coordinate the project!
