  1. Marcos Dracos IPHC-IN2P3/CNRS, Strasbourg EURO and CERN context M. Dracos

  2. θ13 limit expectations up to 2016 never forget that these projects could also observe the 1→3 oscillation ⇒ in this case precision measurements with next projects decisions future facilities M. Dracos

  3. Sensitivity of future projects (ISS) CP Violation sin22q13 • In this context, study extensively in Europe the 3 options: • Super Beam (to Fréjus) • Beta Beam (after EURISOL) • Neutrino Factory • Physics Report: Rept.Prog.Phys.72:106201,2009. • Accelerator Report: JINST 4:P07001,2009. • Detector Report: JINST 4:T05001,2009 • already many citations for these 3 publications M. Dracos

  4. CERN accelerator strategy(by that time) Motivation • Reliability: Present CERN accelerators too old Þ need for new accelerators designed for the needs of SLHC • Performance: Increase of brightness of the beam in LHC to allow for phase 2 of the LHC upgrade.Þ need to increase the injection energy in the synchrotrons • Increase injection energy in the PSB from 50 to 160 MeV • Increase injection energy in the SPS from 25 to 50 GeV • Design the PS2 with an acceptable space charge effect for the maximum beam envisaged for sLHC => injection energy of 4 GeV. Proton flux / Beam power 50 MeV Linac2 Linac4 160 MeV (2014?) (2013?) PSB (LP)SPL 1.4 GeV 4 GeV PS 26 GeV PS2 50 GeV Output energy (2018?) SPS 450 GeV SPS+ 1 TeV LP-SPL: Low Power-Superconducting Proton Linac (4-5 GeV) PS2: High Energy PS (~ 5 to 50 GeV – 0.3 Hz) SPS+: Superconducting SPS (50 to1000 GeV) sLHC: “Super-luminosity” LHC (up to 1035 cm-2s-1) DLHC: “Double energy” LHC (1 to ~14 TeV) LHC / SLHC DLHC 7 TeV ~ 14 TeV M. Dracos

  5. SPL for Neutrino Beams for neutrinos and radioactive beams (including Beta Beams), could be ready by 2020. • The study of LP-SPL has already started at CERN, • CDR for 2.2 and 3.5 GeV HP-SPL already done (CERN 2000-012, CERN 2006-006), • decision and beginning of construction of LP-SPL by 2012/2013, • at that time the design must take into account the possibility to go to HP-SPL, • LINAC4 shielding already designed to go to high power.

  7. Previous European Projects • ESGARD (European Steering Group on Accelerator R&D) created by lab directors • FP6 EU projects: • Integrating Activities • CARE (Coordinated Accelerator Research in Europe) • BENE (Beams in Europe for Neutrino Experiments) • WP1: Physics demands on accelerator facilities (PHYSICS) • WP2: High Power proton drivers (DRIVER) • WP3: High power targets (TARGET) • WP4: High power collection systems (COLLECTOR) • WP5: Novel Neutrino Beams (NOVEL NEUTRINO BEAMS) • Mandate to prepare a Design Study in FP7 M. Dracos

  9. European Strategy M. Dracos

  10. The ESFRI (European Strategy Forum on Research Infrastructures, European roadmap for research infrastructures) committee establishes a priority list for new common infrastructure to which the EU is willing to contribute The Design Studies is the first step in the process to qualify for financing from the EU for the infrastructure For the infrastructure to be constructed a member state(s) or an intergovernmental organization must bid for it and offer an important part of the funding International participation is strongly encouraged What is an EU Design Study? EU call Work Program: Capacities M. Dracos

  11. Studies on neutrino facilities to perform precise measurements of the parameters governing neutrino oscillations. This will require a new high intensity beam-based neutrino oscillation facility in which neutrino beams are generated using new and highly challenging concepts. This Design Study will review all three currently accepted methods of realizing this facility (the so-called neutrino Super-Beams, Beta Beams and Neutrino Factories). It includes a detailed study of the key technical challenges of the accelerator facilities, of the detector options necessary to measure the neutrino oscillation parameters and a comparison of the physics reach of these facilities. The design study will also perform a cost assessment that, coupled with the physics performance, will permit the European research authorities to make a timely decision on the lay-out and construction of the future European neutrino oscillation facility.

  20. Neutrino Related European Projects • Two FP7 projects: • NEu2012 (http://bene.web.cern.ch/bene/NEU2012.htm) • Structuring the accelerator neutrino community • LAGUNA (Large Apparatus for Grand Unification and Neutrino Astrophysics, http://laguna.ethz.ch:8080/Plone) • Design Study for large underground laboratories for astroparticle and neutrino studies • Project started: 1st August 2008 • Duration: 2 years – completion in August 2010 • Budget allocated by EU: 1.7M€ • ECFA • review panel: possible way to help coordination of neutrino activities (decision in Frascati, July 2010). M. Dracos

  21. Recommendations to keep alive the present LHC injection chain (not yet an official decision)! SPL has to be specifically studied for neutrino beams (High Power option). Is this decoupling from LHC plans good or bad for neutrinos (probably bad to very bad)? EUROn has to cost the whole proton driver and not only the part to go from Low Power to High Power. After Chamonix CERN workshop about LHC injectors M. Dracos

  22. It lays the foundation for the next decades of high-energy physics at CERN. Dedicated R&D for neutrino projects will prepare for European participation in neutrino physics at CERN or elsewhere. Examples of short term projects: the possible reconstruction of the neutrino beam line at the PS to perform a final experiment to the LSND anomaly, with a test facility for future detectors, to establish a small core group to prepare for European participation in neutrino physics. This MTP is also driven by the R&D for high-power proton sources, such as HP-SPL, in line with European participation in neutrino physics (the first cost estimate of R&D for a HP-SPL with a CERN contribution towards neutrino physics is included). CERN Medium Term Plan (2011-2015) M. Dracos

  23. Big decisions in HEP will be taken when significant LHC results will be available, date likely to coincide with the EUROn Design Study end (2012-2013). EUROn needs the help of CERN at least for costing and safety issues. European roadmap (to be defined by the CERN Council) has to take into account the international context (USA and Japan). Future neutrino beams R&D will be included in the CERN MTP. In all cases, it would be better if Europeans elaborate a common position. Wait for 2012-2013, new q13 results could modify the present landscape… Conclusions M. Dracos
