  13. Next steps (1/2) • Proton decay • Dark matter • Confirmation of atmospheric oscillation and better knowledge of m2 • accelerator long-baseline  disappearance experiments: K2K (running) and NUMI/MINOS (2005) • Atmospheric neutrinos with 30-50 kt tracking calorimeter (MONOLITH) • Prove if atmospheric oscillation is between nmand nt or else • detect t appearance CNGS project, OPERA, ICARUS • Confirm solar oscillations and better knowledge of m2 • NC vs CC measurements in solar flux by SNO • reactors anti e @ O(100 km) KAMLAND • Redundant information on solar oscillation • GNO, SNO, BOREXINO, LENS (oscillation in a single experiment) • Further limit, or measure Ue32 • SN ’s • low energy (2 GeV), high intensity  beam, look for   e • nu-factory (in the far future) A. Bettini. INFN

  14. Next steps (2/2) • How small is tan223 – 1? • Few GeV  beam 10 mrad off axis • Sign of Dm2 • super MONOLITH (100 kt), magnetised • SN ’s • Neutrino-less double beta decay •  (super) beam • nu-factory • Nature of neutrinos: Majorana or Dirac • Neutrino-less double beta decay • Measure absolute values of the masses.

Bettini. INFN

  15. More space needed for • Neutrino-less double beta decay • Experiments are becoming large (15 m diameter) • Dark matter • Experiments may become large • Crystal grow underground? • Atmospheric  30 - 100 kt magnetic detectors Needs order of 100 m x 30 m • Proton decay • does not need to be very deep • needs (multi?) megaton size •  beam and nu factory • can be shallow • may need more than one site • Next generation GW detectors (both interferometer and cryogenic antennas) A. Bettini. INFN

  16. Dark matter search Experiments in the European Underground Laboratories are world leading, but orders of magnitudes in sensitivity must be gained to explore the theorists’ parameters space. need experiments with clear signature (annual modulation of rate or recoil direction Continental coordination will help 10 ev/(t d) 10–2 ev/(t d) A. Bettini. INFN

  17. M = Detector mass t = Exposure time b = Background rate D = Energy resol. Towards (absolute) neutrino mass Majorana neutrino mass is predicted a few tens meV in most scenarios Increase Mand decrease b without compromising b For one order of magnitude in neutrino mass increase by two orders of magnitude sensitive mass  O(1 t) decrease by two orders of magnitudeb O(1event/(keV t yr)) Nuclear physics effects must be calculated to go from a limit on lifetime to a limit on neutrino mass. Uncertainties: factors 2-3 A. Bettini. INFN

  18. Two complementary Support Actions • Support actions under thematic priorities • Integrated Projects • Networks of Excellence • ……. • …….. • Support to research infrastructures • Transnational Access (TARI) • Integrated Infrastructures Initiatives • Communication Network Development • Design studies • Construction and Upgrading of Infrastructures of interest for underground facilities • Integrated Infrastructures Initiative may include • Networking (compulsory) • Transnational Access (TARI). Very similar to FP5 • Joint Research Projects (JRP) • excludes design studies and construction of new infrastructures A. Bettini. INFN

  19. Research Infrastructures in FP6 “Research infrastructure” is a ”facility or resource which provides essential services to the research community”, and/or “infrastructural centres of competence which provide a service for a wider research community based on an assembly of techniques and know-how” example. a gamma ray telescope is a RI only if users outside the collaboration that built it are allowed Support of European research infrastructures aims “to ensuring access to infrastructures to conduct research and to promote the optimum development of new or upgraded infrastructures”. An important fraction of Astroparticle Physics, but not all, needs Underground Laboratories A large fraction of Underground Science is not Astroparticle Physics Nuclear Astrophysics, Long-baseline neutrinos, (Double-beta decay, Proton decay,) Geology, Biology, etc Underground Science Laboratories need an Integrated Infrastructure Initiative for Underground Science Laboratories = I3USL http://europa.eu.int/comm/research/nfp/infrastuctures.html A. Bettini. INFN

  20. Networking in an I3(USL) • Networking is the only compulsory element • Funding from the Community may reach 100% of the budget • Strategically it aims to contribute to structure the European Research Area • The action is clearly infrastructure-oriented, well suited for underground labs (not for experiments) • In practice it must aim to • provide governance and auditing to the program (consortium management) • foster co-operation in new instrumentation, methods and techniques • optimise the use of infrastructures • disseminate knowledge to potential users, including industries (e.g. SMEs) • foster technology transfer to • industry • environmental Agencies • other fields • archaeology • geology • biology A. Bettini. INFN

  21. TARI in an I3(USL) • Transnational Access to Research Infrastructures action • may be inside or outside an I3 • supports access to one or more, not necessarly all, infrastructures of the I3 • is very similar to FP5 • the support covers the total costs of the access • travel and subsistence of the users (maximum 3 months a year) • priority to first-time users and to users from countries without similar infrastructures • fees per access day (to be negotiated) or actual overcost for the new users • the support must be a small fraction (in any case < 20%) of the operating cost of the facility to avoid undue dependence • expected between 100 k€ and 750 k€ • No capital costs A. Bettini. INFN

  22. Experience at LNGS with TARI in FP5 LNGS has won a TARI contract in FP5 (28 months duration) An infrastructure is seen by EU mainly as a facility, which is not exactly a subnuclear physics laboratory Typical “experiments” should require the use of the facility for a few weeks (maximum three months) Typical usersshould be new ones LNGS present TARI contract is 160 k€/yr (2% of operational cost) Requests and available money looks to be roughly in equilibrium Most used facilities are: 50 kV LUNA1 accelerator, low background facilities for multidisciplinary measurements, geology facilities, biology (i.e. non-astroparticle) Contract is important mainly for fostering spin-offs and training new personnel Size of the TARI element on a 5-year I3 is about 1 M€ A. Bettini. INFN

  23. Joint Research Programs in an I3(USL) • Must aim to develop the service provided by the infrastructure in a particular field, technique or instrumentation • Funding by the Community will be < 50% of budget • Examples • Laboratory Infrastructure Activities • Techniques for measurement and monitoring of experimental parameters of the labs. • Control and reduction of radon • Neutron background study in different labs • Low background radioactivity measurements of materials and components • potential exploitation of results by SMEs • Fabrication of materials and detector components in the underground site • for instance, shields, growing and manufacturing of crystals • Exchange of information about ultra-low radioactive background and purific. techniques • Design and study of shielding • Co-operation in outreach activities • Optimisation of safety and environmental procedures and policies • Coordination in Astroparticle Physics Experiments & Observatories • Neutrino physics • Next generation double-beta decay (10 meV scale) • Next generation Gravitational Waves detectors • Dark Matter detection with directional sensitivity devices A. Bettini. INFN

  24. Proposal • Proposal must contain a Draft Programme, outlining for each activity • Objectives and intended impact (improve co-ordination, increase access, improve instrumentation,… • Multi-annual execution plan, including milestones and derivables • Detailed plan for first 18 months • Outline of the integration of activities programme • Specification for each activity the responsibility of each partner, including the contributed resources • Identify and justify the budget for each activity, the fractions contributed by the partners and those requested to the Community. • Management structure • First call is expected by end 2002-beginning 2003. Time is very short. • Appoint • a steering committee made of the five lab directors • a drafting group: a member for each laboratory • Define interaction/approval feedback with Appec A. Bettini.
