The Deep Underground Lab activities within ILIAS R&D on Low background techniques for Deep Underground Science Network of the EU Deep Underground Laboratories Transnational Access to the Deep Underground Laboratories Support for the access of research teams to the underground labs (travels, subsistence, technical support), specially in support of less favoured countries Networking of the Underground Labs for: - service and facilities improvement, and extention of the underground sites - Safety problems and accident prevention - Communication, outreach, and scientific coordination R&D to strengthen and enlarge the low background facilities in the underground labs IDM2004 – Edinburgh, 10-sep-04
18
Deep Underground labs in Europe are major infrastructures where important experiments on fundamental rare-event and astroparticle physics are underway : - dark matter searches - double beta decay - neutrino physics and astrophysics - nuclear astrophysics ILIAS gives the opportunity to start an effective collaboration among the labs and with the astroparticle physics community based on networking coordinated transnational access to the 4 infrastructures joint R&D on low background techniques IDM2004 – Edinburgh, 10-sep-04
