IMPROVEMENTS IN TE-130 DOUBLE-BETA DECAY SEARCH WITH CRYOGENIC TEO2 ARRAY DETECTORS

Single crystal TeO2 bolometers have been used since 5 years ago to sea rch for neutrinoless DBD of Te-130. During the last year, our group ha s been studying and preparing the first array of 4 crystals, 340g each , opening this technique to new frontiers in rare events' physics. The results and perspectives of this second generation cryogenic detector s are here reported and discussed, with particular emphasis on the pec uliarities which make them feasible for a consistent upgrading of our previous result in DBD search.
