JRA1. LBT-DUSLJRA1. LBT-DUSLLow background techniques for deep Low background techniques for deep underground sciencesunderground sciences


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.

• Improvement of a low background Ge detector (IRIS, 400 cc).Prospective construction materials are being measured. Monte Carlo simulations are performed to get the distinct contribution to the background from the assembly materials and to determine the maximum acceptable radioactivities in order to get an improvement of a factor 5 in the detector background.We’ve found a high Th activity (0.13 Bq/kg @ 238 keV) in one of the insulators near the crystal, which need to be replaced by other material.
