  1. EURO A High Intensity Neutrino Oscillation Facility in Europe • Introduction • Superbeam • Neutrino Factory • Beta beams • Detectors • Physics • Possible next steps

  2. EUROnu • FP7 Design Study • Due to limited funds: focus on possible “next” generation neutrino oscillation facilities in Europe • CERN to Frejus superbeam • Neutrino Factory (in collab. with IDS-NF) • Beta beams • + performance of baseline detectors and physics reach • Output: comparison of physics, “cost” & risk • Reported to CERN Council via SG/ECFA • Project started: 1st September 2008 • Duration: 4 years – completion in August 2012

  3. Partners

  4. Structure

  5. EUROnu Status • Baselines largely defined • Design work still continues • Moving more towards “engineering” • Costing: • WBS being done • Framework being created using cost tool • Workshop planned soon • Safety and risk also to be done • Midterm technical review taking place • 19 months left!

  6. Super-Beam • Design of CERN to Frejus SB based on SPL

  7. Super-Beam • Design of CERN to Frejus SB based on SPL • Parameters: • 4MW beam: HP SPL • 5 GeV k.e. protons • 130Km baseline • Focus on solution for target + collector • Determine performance for Physics reach

  8. SB - Target • Preference: static solid target • Mercury jet – non-starter: • needs magnetic field containment • interaction with horn • not simple • Low Z and 4 targets: small extrapolation • Initial thoughts: 4*single graphite/beryllium target

  9. SB - Target

  10. SB - Target Pebble-bed target

  11. SB - Horn • Baseline: • Miniboone shape • Aluminium • Cooled with internal water jets • Pulsed with 300-350kA • Looks fine from stress and fatigue • Lifetime due to radiation needs study

  12. SB - Horn Very preliminary

  13. Neutrino Factory • Close collaboration with IDS-NF • IDR almost ready Muon front-end Muon acceleration

  16. NF – Pion capture

  17. NF – Pion capture

  18. NF – Front-end Status: - advanced - awaiting MICE results - RF studies - alternatives under study

  19. 244 MeV 0.9 GeV 146 m 79 m 0.6 GeV/pass 3.6 GeV 264 m 2 GeV/pass 12.6 GeV The linac consists of SC RF cavities and iron shielded SC solenoids grouped into three types of cryo-modules. NF – Acceleration LINAC RLA I RLA II Chicanes have a vertical dipole spreader, horizontal bending magnets, quadrupoles for transverse focussing and a vertical dipole combiner. The RLAs consist of single SC RF cavity cells and FODO quadrupole focussing throughout.

  20. NF – Acceleration Non-scaling FFAG: Conceptual design advanced. Engineering being started. But, no such machine ever built. Commissioning underway.

  21. Beta-Beam • Main issue in EUROnu: maximise ion production • 2 options being considered

  22. EURISOL Beta Beam:18Ne and 6He BB – Ion production • Production • ISOL method 18Ne 2x1013/s<8x1011/s6He 2x1013/s>1x1013/s • direct production being studied • Updated Beta Beam: 8Li and 8B – higher Q isotopes • ion production ring 8Li 1014/s 8B >1013/s

  23. BB – Ion production But: >5* more ions – difficult to accelerate 8B looks very difficult 18Ne looks possible, though experiment required

  24. BB – Ion production New baseline Work continues to optimise ion production rate

  25. BB – Ion production Possible Needs experiment Challenging

  26. Limited funding: only performance and “cost” • Concentrate on baseline detectors • Magnetised Iron Neutrino Detector - NF • Large water cherenkov – SB and BB • Near detectors • Hoped Laguna would be able to do LAr, e.g., ! Detectors

  27. 50-100 m 15 m n beam 50-100kT 15 m B=1 T iron (3 cm) + scintillators (2cm) • Golden channel signature: “wrong-sign” muons Detectors - MIND IDS-NF baseline for 25 GeV NuFact: MIND • Far detector: 100 kton at 2000-4000 km • Magic detector: 50 kton at 7500 km • Appearance of “wrong-sign” muons • Segmentation: 3 cm Fe + 2 cm scintillator • 1 T magnetic field

  28. New analysis with Nuance and GEANT4: signal efficiencies • Systematic errors: ~1% • Background: ~10-4 Detectors - MIND Numu efficiency Anti-numu efficiency

  29. MEMPHYS: 3x65mx60m water Cherenkov modules (400 kton fiducial) but could be expanded to 3x65mx80m (572 kton) • Either SPL Super Beam or CERN Beta Beam to Frejus tunnel in Modane, France, 130 km from CERN. • 81,000 12” PMTs (30% coverage) Detectors - WC MEMPHYS 440 kt 65m 60m EuroNu, RAL, 19 January 2011

  30. R&D underway: new PMTs and readout electronics • Prototype: MEMPHYNO under construction • New WC simulation Detectors - WC MEMPHYS: interactive μ+500 MeV

  31. Physics performance • Optimisation: • baselines and energies • synergies: experimental setups and facilities • Systematics Physics

  32. Next Steps • Technical review: April/May • ECFA Neutrino Panel • Independent assessment • IDS-NF IDR • EUROnu annual report • CERN Strategy Review: kick-off this summer report next summer • EUROnu contribution under discussion • EUROnu future: also under discussion
