  1. Laboratoire Souterrain de ModanePast - present - future Gilles Gerbier CEA/LSM

  2. Fréjus peak Bardoneccia Torino Modane Chambéry 1982 : LSM Entrance of road tunnel Modane COMMISSARIAT À L’ÉNERGIE ATOMIQUE DIRECTION DES SCIENCES DE LA MATIÈRE

  3. 1984-1988 Fréjus Proton Lifetime « DVP » 900 tons of Fe geigers tubes + plasma tubes

  4. The lab now • 1750 rock above • 4800 mwe • Dry and warm (32 °) • 4 muons /m2/ day • 1 .6 10-6 fast neutrons/cm2/s from • rock/concrete radioactivity • air continuously renewed : 1.5 vol/hour • very low Rn concentration 5-15 Bq/ m3

  5. 100Mo 6914 g 216.4 days 4.10 kg.y Data bb2n Monte-Carlo Radon Monte-Carlo Ec1+Ec2 (keV) bb0n T1/2 = 3.5 1023 NEMO 3 bb expt with 100Mo IN2P3, Dubna, Moscou, Prague Mo 22 results 2004

  6. Detector enclosed in tent Radon trapping facility => 150 m3/h : reduction from 10 to 0.02 Bq/m3 de radon Data taking for 5 years => eff mass < 0.3 eV NEMO3 – january 2005

  7. Hunting for galactic dark matter WIMP’s Detection volume 50l Copper 20 cm lead shielding He tank EDELWEISS II Start installation jan 2005 Data taking: autumn 2005 w. 28 detectors (9 kg) Upgrade possible up to 36 kg 10 layers of 12 detectors of 320 g EDELWEISS-I present EDELWEISS-II sensitivity goal 1 Ton sensitivity goal (optimistic) July 6 2002 -GG

  8. Polyethylen shield mounting March 2005

  9. Super Heavy elements In Nature Dubna –CSNSM expt Eka–osmium (Z 108, A 286) Detecting decay by multi neutron evt from Os sample in neutron detector with 60 3He counters Goal :Sensitivity 10-22 g/g 3He-counters Neutron moderator Sample (Os-500 g) Installed at LSM since 2004

  10. Germaniums – 13 detectors (unique world wide) for low level radioactive counting Bordeaux wine dating with 137Cs

  11. About 150 physicists, engineers, techs from enlarged Europe come to LSM + few from US and Japan Project of joint laboratory with Dubna : JOULE JOint Undergroung Lab in Europe LSM

  12. IUS Institute of Underground Science, Boulby Mine, UK Pyhasalmi lab LSM Finland Laboratoire Souterrain de Modane, France LSC Laboratorio Subterraneo de Canfranc, Spain LNGS Laboratori Nazionali del Gran Sasso, Italy The EU Deep Underground Labs

  13. Running the lab : people Team in Modane Safety control Partially in Modane Chargé mission MégT Luigi Mosca Sécurité IN2P3 Cyril Thieffry Sécurité DAPNIA Alain Le Saux Charlotte Riccio

  14. New safety galery SFTRF digs new galery start 2006 end 2009 New excavation ?? Projets

  15. Mid 2009 : the two digging machines meet at LSM location =>possibility of 15 000 m3 extension Safety galery Actual lab 3 500 m3 Full… 15 m Extension 15 000 m3 Road Tunnel Benefits of infrastruture for digging and excavating Little impact on total excavation (< 7 %) => low cost

  16. What for ? • NB : 15 000 m3 = 40 % of 1 Gran Sasso hall = 1.5 % of Megaton cavity • Well adapted for • Third generation bb and dark matter WIMP searches (100 kg to 1T) looking for deep sites • « Small » size neutrino detectors • Dedicated low level radioactive environment (integrated neutron shield/m veto, radon reduced atmosphere) • SuperNemo bb (10 000 m3), Eureca DM (2 000 m3), neutrino coherent detection (1 000 m3), LXe,…

  17. Hopefully completed by spring 2007 Infrastructures in Modane town : offices, garage/storage, appartment

  18. Conclusion • New physics results in coming 5-7 years • New generation experiments coming on-line • Local infrastructure ready to welcome ambitious program • Welcome to the afternoon visits • Welcome back for physics together in few years …
