Abstract

In the last 10 years bolometers have become extremely powerful detectors in the search for rare events, due to their very good resolution. Cuoricino, a 62 bolometer array, in the first months of activity reached a resolution (average in all detectors) in the energy region of interest (2528 keV) of 7 keV and a limit on the t1/2 of the process of 7.5·1023y. Cuoricino’s 62 detectors constitute the biggest number of macrobolometers (790 g each) ever cooled and demonstrate the feasibility of large arrays of bolometers. Following the indication of Cuoricino in CUORE R&D a new detector has been developed trying to improve the reproducibility of the detector’s performance, to increase the single detector mass (to reduce the number of channels) and to simplify the experiment assembly. The latest results are presented.
