WP 1.WP 1.

Key objectivesKey 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.


WP 2.WP 2.


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.


WP 3.WP 3.


-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.


WP 4.WP 4.


-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.
