1 ILIAS 3 EB meeting. Paris. October 2004 JRA1 web page http://www.unizar.es/ilias 1 Present status Present status Work in progress Work in progress JRA1. LBT-DUSL Low background techniques for deep underground sciences

2 ILIAS 3 EB meeting. Paris. October 2004 JRA1 web page http://www.unizar.es/ilias 2 WP 1. Key objectives To measure the environmental background components (neutrons, gammas, muons, Rn contamination in the air and in the water...) in the four underground sites in a coherent and coordinated way. The joint research effort should optimise the know-how of the different participants. This is extremely important for the interpretation of data and for planning future experiments.

3 ILIAS 3 EB meeting. Paris. October 2004 JRA1 web page http://www.unizar.es/ilias 3 WP 2. Key objectives To produce a reliable Monte Carlo library of simulation codes to identify and quantify the backgrounds in the EU underground sites in a variety of experimental conditions for the interpretation of data and for planning future experiments. The joint research effort should optimise the know-how of the different participants. Experimental results from Task 1 will be useful as the input of the simulations.

4 ILIAS 3 EB meeting. Paris. October 2004 JRA1 web page http://www.unizar.es/ilias 4 WP 3. Key objectives -Construction and upgrading of ultra low background facilities (ULBF) in the four underground labs forming an EU-coordinated service for applications in rare event physics and other fields of world-wide value. -Implementation of new techniques to deal with the background: active and passive shielding, veto systems, particle discrimination techniques, fragmentation of calorimeter detectors, control and suppression of radon levels... -Study of the feasibility of fabrication of detectors and materials underground.

5 ILIAS 3 EB meeting. Paris. October 2004 JRA1 web page http://www.unizar.es/ilias 5 WP 4. Key objectives -Collect new (and old) data on radioactive contamination and cosmogenic activation of materials used in rare-event physics experiments and ultra-low background instrumentation, using the new capabilities offered by the R&D and facilities of WP 3. -Development and test of purification techniques to improve the radio-purity of materials.
