Although the existence of neutrino oscillations seems now to be well proved, several neutrino properties are still unknown. We know, for example, that neutrinos are massive but we ignore what the absolute scale of these masses is. The measurement of neutrino masses and mixing angles (and phases), as well as the assessment of the Dirac/Majorana character of neutrinos, will be the goal of the next generation experiments. 
In this scenario a unique role is played by Neutrinoless Double Beta Decay searches (which represent the only experiments able to prove the Majorana character of neutrinos while obtaining informations on the neutrino mass hierarchy and Majorana phases). Low Temperature Detectors (LTD) have already proved to be powerful - and highly competitive devices - in this field. Proposed for Rare Events Searches in 1984 by E.Fiorini and T.Niinikovsky, they were pioneered in the course of the last 20 years by the Milano Weak Interaction Group which developed large mass TeO2 arrays to study Neutrinoless Double Beta decay of 130Te, an experience that culminated in the MiDBD experiment.

The test bench for CUORE have been the CUORICINO experiment working since 2003 in Laboratori Nazionali del Gran Sasso (L'Aquila, Italy).
