  1. Modane Underground Laboratory Past, present, future extension CNRS and CEA Gilles Gerbier – IRFU-Saclay http://www.lsm.in2p3.fr

  2. Modane Underground Laboratory

  3. Laboratoire Souterrain de Modane

  4. Laboratoire Souterrain de Modane Depth: 4800 m.w.e. deepest (running) lab in Europe Surface::400 m2 Volume : 3500 m3 Muon flux: 4 10-5 µ.m-2.s-1 5 times lessthan LNGS Neutrons: Fast flux: 4 10-2 n.m-2.s-1 Thermal flux: 1.6 10-2 n.m-2.s-1 Radon: 15 Bq/m3 Access : horizontal Budget (full cost): 1 M€/yr Staff: 3 Physicists 3 Engineers 7 Technicians International associated laboratory agreement with JINR Dubna (Russia) and CTU Prague (Czech Republic)

  5. Laboratoire Souterrain de Modane From a particle physics experiment to a multi-science plateform 1990- 2000 1979 - 1981 1982- 1990 2000 - …. tpExperiment Prototypes Experiments Construction Neutrino: double beta decay, double EC Darkmatter Nuclear structure Logical test failures in microélectronics Proton decay Ultra lowradioactivitymeasurement:Environmental sciences, applications, expertises

  6. Neutrino physics: NEMO -3 Double beta decay : Tracking + calorimeter - 100Mo 7 kg

  7. Dark matter: EDELWEISS Bolometric technique: Heat + Ionization Ge crystals - 40 kg preliminary x 2

  8. Other experiments Neutrino physics Double EC search (106Cd) TGV-II (Ge with sheets of Double EC candidates) Nuclear physics Super Heavy Element In nature SHIN (osmium ore surrounded by 3He neutron detectors) TGV II SHIN BiPo(related to SuperNEMO, measurement of thin film at the level of 1 µBq/kg) MIMACprototype (Darkmatter TPC for DM directionaldetection) SEDINE spherical detector prototype (neutron, n, DM…) soon MEMPHYNO prototype for megaton – scalecherenkov detector

  9. Scientific activities @ LSM Neutron detectors at LSM Sphere TPC 3He counters Gd loadedliquidscintillator Support from ILIAS TARI for the 3 detectors Radon detectors – sensitivity ~1 mBq/kg (electrostatic collection of radon daughters) Saga University (Japan) and Dubna (Russia))

  10. Gamma ray spectroscopy @ LSM 14 HPGe from 7 different laboratories of CNRS , CEA, JINR DUBNA and CTU Prague are available at LSM • - Material selection for astroparticle physics, • Environnemental research (oceanography, • climat, retro-observation,….) • - Environmental survey • - Applications (wine datation, salt origin,…) • - Developements of Ge detector (ILIAS)

  20. SuperNEMO @ DOMUS SuperNEMO @LSM SuperNEMO: Double beta decay 20 modules 100 kg of 82Se (or 150Nd, 48Ca) Sensitivity on mn: 40 – 100 meV

  21. EURECA infrastructure EURECA@DOMUS EURECA @LSM European consortium Edelweiss + CRESST + 4 labs 1 t of cryogenics detector DM +bb EURECA 1 t

  22. Other@DOMUS EURECA @LSM Other possible projects - DARWIN multiton Ar/Xe for DM search - Large sphere (5m diam) for SN watch ≈ room for two medium  size projets

  23. LSM Extension project status LSM extension • Safetygaleryworkstarted in September 2009 • Excavation of the extension 2014 or 2015. • In operation in 2016. • Detailedstudiesfunded by Savoie departement and Rhone-AlpesRegion • Agreement fromMinistery and CNRS for the project • Funding in progress (85% alreadyobtained CNRS, • RegionRhone-Alpes, FEDER funds) • Technical discussion in progress
