  1. Neutrino challenges and detector needs AIDA Horizon 2020 Meeting CERN, 17 February 2014 Paul Soler

  2. Contents Motivation Future Neutrino Experiments European Neutrino Physics CERN Neutrino Facility WA104: ICARUS-NESSIE WA105: GLACIER-MIND AIDA-II opportunities Conclusions P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  3. Motivation – reactor experiments • Notwithstanding the impressive discovery of the Higgs boson in 2012, neutrino physics has produced some of the most exciting results in particle physics over the last 15 years. • Also in 2012, Daya Bay and RENO discovered that q13>0, and found that it was much larger than expectedCP violation? P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  4. Motivation – T2K • Recent T2K result confirms large value of q13 but is at tension with reactor results, maybe suggesting large value CP phase d: P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  5. Motivation – Neutrino Physics • Some concern of neutrino experiments: they do not cover a broad range of physics topics like collider-based experiments • Practically every neutrino experiment in last 15 years has made significant, important discovery to further particle physics • Excellent track-record of successful experiments: • Super-Kamiokande: neutrino oscillations (q23), solar neutrinos (q12), … • Sudbury: solar neutrinos due to neutrino oscillations in sun (MSW effect) • DONUT: discovery of nt • KamLAND: long-baseline reactor and independent confirmation of q12 • K2K: accelerator-based confirmation of q23 • MINOS: measurement q23 and Dm223 at long-baseline experiment • MiniBooNE: still inconclusive sterile neutrino search!! • OPERA: confirmation that nt responsible for long-baseline oscillations • ICARUS: establishing liquid argon for neutrino physics (limits on steriles) • Daya-Bay, RENO, Double-Chooz: discovery q13 • T2K: confirmation of q13 through accelerator-based neutrino oscillations P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  6. Future Long-baseline Experiments • Next generation of long-baseline neutrino oscillation experiments at accelerators aims to: • Determine mass hierarchy: sign Dm132 • Determine whether q23=p/4. If not, is q23<p/4 or q23>p/4? • Determine CP violation in neutrinos and measure d • In Japan: Hyper-Kamiokande • (1 Mton water Cherenkov) • In USA: LBNE • Fermilab-Homestake: 1300 km • Assumes 10-35 kton liquid argon at SURF, Homestake P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  7. European Neutrino Physics • In Europe: LBNO • CERN to Pyhasalmi (Finland): 2300 km • Initial mass: 20 kton double-phase liquid argon • Upgrades up to 70 kton • CERN Expression of Interest: • CERN-SPSC-2012-021, SPSC-EOI-007 • Also, ~1Mton water Cherenkov at ESS • European Strategy for Particle Physics • ICFA Neutrino Panel: develop world-wide neutrino roadmap and R&D GLACIER P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  8. CERN Neutrino Facility (CENF) • Based on the recommendation of the European Strategy, CERN responded by creating a CERN Neutrino Facility (CENF) for detector R&D and by approving in August 2013 two experiments for liquid argon R&D • ICARUS-NESSIE: ICARUS single-phase liquid argon detector and air core spectrometer (NESSIE) - known as WA104 • LBNO: demonstrator for double-phase liquid argon detector (GLACIER) and Magnetised Iron Detector (MIND) – known as WA105 • The CENF should be a facility to carry out neutrino detector R&D in Europe and to concentrate European efforts towards long-baseline neutrino experiment regardless of location of experiment (ie. Europe, USA or Japan) – led by Marzio Nessi • Prepare infrastructure in Bat 185 for ICARUS refurbishment • Equip EHN1 hall in Prevessin for single and two-phase liquid argon • Develop charged particle test beams for EHN1 (H2 and H4) • Launch R&D for neutrino beam line in North Area P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  9. Plans for CENF • Two MoUs with institutions involved in both WA104 and WA105 are currently under negotiation with CERN: • WA104: rebuild ICARUS T600 (Bat 185) for either CERN or Fermilab • WA104: R&D on large Lar TPC (T150) • WA104: R&D on air core muon spectrometer • WA105: R&D on large double-phase (GLACIER) prototype • WA105: R&D on MIND muon tracking detector • CERN will contribute to logistical effort of WA104 and WA105: cryogenics, cryostats, controls, DAQ, magnets, integration, host of facility and scientist support. • Start conversations between European and US groups on common long-baseline experiment • Plans currently under negotiation so details not ready. However, AIDA-II should be part of this overall package to create community of interested parties P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  10. Plans for CENF • CENF in North Area (EHN1) • Large area for both ICARUS-NESSIE and GLACIER-MIND tests • Access to charged particle beams H2 and H4 Plan view P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  11. Plans for CENF • CENF in North Area (EHN1) • Large area for both ICARUS-NESSIE and GLACIER-MIND tests • Access to charged particle beams H2 and H4 Elevation view P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  12. Plans for CENF MIND Charged beams for all experiments Explore possibility n beam • CENF in North Area (EHN1) • Large area for both ICARUS-NESSIE and GLACIER-MIND tests • Access to charged particle beams H2 and H4 LAGUNA-PROTO ~64 meters New detectors? NESSiE P. Soler, AIDA Horizon 2020 meeting, 17 February 2014 ICARUS T150

  13. Plans for CENF Marzio Nessi, Jan ICFA meeting • Ongoing/planned activities with CERN participation: • Preparing movement of ICARUS600 to CERN • Preparation of Bat185 for ICARUS and Bat182 for LAGUNA • Participation in the design, engineering and procurement of the new WA104 and WA105 cryostats • Participation in the definition of a possible cryogenics project at CERN for WA104/5 • A feasibility study for a large superconducting magnet to be put around WA104, starting with the small WA104-ICARUS150 and/or participation in the air core magnet project of WA-104-NESSiE • Detailed integration study for the EHN1 extension done, ready for CE engineering detail design • In the December CERN FC approved a contract for all CE studies and drawings preparation • Detailed project definition for charged beams in the EHN1 extension • Definition for all the above of the necessary safety and environmental studies • Preparation of budget request for the above and finalization of necessary MOUs with WA104 and WA105 • Initial discussions with the US groups on a possible common R&D (long term and short term plans) P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  14. WA104 Plans • Overhaul of ICARUS T600 module in Bat 185 • T150 ICARUS module • R&D on magnetisation • NESSIE air core magnet • MoU under negotiation P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  15. WA105 Plans • Build double-phase prototype (6×6×6 = 216 m3): 300 ton fiducial • Develop required infrastructure and technology for prototype • MoU currently also under negotiation P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  16. AIDA-II contribution • Not clear yet what part of WA104 or WA105 could be covered within AIDA-II since both MoUs are currently under discussion • However, could use MIND being constructed for AIDA (WP8.5.2) as part of infrastructure, for test beam measurements • AIDA low energy beam design can be recycled for H2 and H4 • More discussions will need to take place P. Soler, AIDA Horizon 2020 meeting, 17 February 2014

  17. Conclusions • We are in an exciting time in neutrino physics: next generation of long-baseline neutrino oscillation experiments could establish CP violation in neutrino sector • Europe has a role to play (wherever the next long baseline experiment may be!) due to its leadership in liquid argon detector R&D • CERN Neutrino Facility (CENF) will be European contribution to world-wide effort and will provide important test-bed for future liquid argon TPC technology • AIDA-II has role to play in developing European neutrino detector community and contributing to CENF, but discussions ongoing on what part of CENF could be covered through new Horizon 2020 funding of AIDA-II P. Soler, AIDA Horizon 2020 meeting, 17 February 2014
