  23. Integrated Large Infrastructures for Astroparticle Science ILIAS ILIAS is an initiative supported by the European Union (6th Framework Programme) with the aim to support the European large infrastructures operating in the astroparticle physics sector.

  24. 3 groups of activities • The ILIAS project is based on 3 groups of activities: • Networking Activities • (N2) Deep Underground science laboratories • (N3) Direct dark matter detection • (N4) Search on double beta decay • (N5) Gravitational wave research • (N6) Theoretical astroparticle physics • Joint Research Activities (R&D Projects) • (JRA1) Low background techniques for Deep Underground Science • (JRA2) Double beta decay European observatory • (JRA3) Study of thermal noise reduction in gravitational wave detectors • Transnational Access Activities • (TA1) Access to the EU Deep Underground Laboratories

  25. JRA1 (Joint Research Activities 1): Low background techniques for deep underground sciences (LBT-DUSL) • Objectives: • Background identification and measurement (intrinsic, induced, environmental) • Background rejection techniques (shielding, vetoes, discrimination) Working packagesWP1: Measurements of the backgrounds in the underground labsWP2: Implementation of background MC simulation codesWP3: Ultra-low background techniques and facilitiesWP4: Radiopurity of materials and purification techniques A vast R&D programme on the improvement and implementation of ultra-low background techniques will be carried out cooperatively in the 4 European Underground Laboratories.

  26. A fifth Underground Laboratory within ILIAS: The CUPP - Centre for Underground Physics in Pyhäsalmi The project to host an underground laboratory in the mine was started in 1993, and the Centre for Underground Physics in Pyhäsalmi (CUPP) was physically established in 2001. A preliminary study, including some background measurement and rock analysis has been made The old part of the mine: There will be plenty of free space to host and storage experiments The new mine started to operate in July 2001. It extends to the depth of 1440 m (4000 mwe). The largest cavern that can be easily constructed is 100 x 15 x 20 m3. An example of the layout

  27. SUL - Solotvina Underground Laboratory It was constructed in 1984 by the Institute for Nuclear Research (Ukrainian National Academy of Sciences). It is situated on the west of Ukraine, in Solotvina near the border with Romania. The principal scientific goal is the search of double beta decay 1 Main hall 30 x 20 m2 (h 8 m)+ 4 small halls3 x 6 m2 (h 3 m)
