Improvements in cryogenic thermal detector performances have triggered new generation experiments based on this devices.

Abstract
Improvements in cryogenic thermal detector performances have triggered new generation experiments based on this devices. MiBeta detector had shown, during the last five years, the potential of a large mass cryogenic detector for long running time, good energy resolution, low energy threshold and low radioactive background experiment. Starting from this point a new very large cryogenic detector was proposed: CUORE (Cryogenic Underground Observatory for Rare Events). CUORE will be a segmented detector made with 1000 crystals of TeO2 of 5×5×5 cm3, for a total detector mass around 760 kg. Thanks to the high granularity a considerable improvement in background rejection can be reached using coincidence analysis between crystals. The main goal of CUORE will be the search of neutrinoless double beta decay of 130Te but also other studies are possible; in particular dark matter and solar axion searches. To prove the feasibility of CUORE a pilot experiment named CUORICINO was proposed and also founded. The estimated sensitivities of CUORICDMO and CUORE for WIMPs searches is here reported.
