Potential and Prospects for CUORE and CUORICINO experiments
The CUORE (Cryogenic Underground Observatory for Rare Events) experiment projects to construct and operate an array of 1000 cryogenic thermal detectors of a mass of 760 g each to investigate rare events physics, in particular, double beta decay and non baryonic particle dark matter. A first step towards CUORE is CUORICINO, an array of 56 of such bolometers, currently being installed in the Gran...
متن کاملCryogenic Double Beta Decay Experiments: CUORE and CUORICINO
Cryogenic bolometers, with their excellent energy resolution, flexibility in material, and availability in high purity, are excellent detectors for the search for neutrinoless double beta decay. Kilogram-size single crystals of TeO2 are utilized in CUORICINO for an array with a total detector mass of 40.7 kg. CUORICINO currently sets the most stringent limit on the halflife of Te of T 1/2 ≥ 2.4...
متن کاملThe CUORICINO and CUORE double beta decay experiments
After an introduction on the various experimental techniques to be adopted in searches for double beta decay, the new approach based on the use of cryogenic low temperature detectors is described. The present results are reported on the limit for neutrinoless double beta decay of 130Te obtained with the large bolometric detector CUORICINO. This setup consists of 44 cubic crystals of natural TeO...
متن کاملStatus of Cuore experiment and last results from Cuoricino
CUORE is a cryogenic-bolometer detector consisting of 988 TeO 2 crystals, 750 g each, operated at a temperature of ∼8 mK, currently under construction in the underground Laboratori Nazionali del Gran Sasso. Its goal is to search for neutrinoless double beta decays with a sensitivity to the effective neutrino mass as low as a few tens of meV. CUORICINO, its pilot experiment, has proven the feasi...

Next-generation experiments searching for neutrinoless double-beta decay must be sensitive to a Majorana neutrino mass as low as 10 meV. CUORE , an array of 988 TeO2 bolometers being commissioned at Laboratori Nazionali del Gran Sasso, features an expected sensitivity of 50– 130 meV at 90 % C.L. The background is expected to be dominated byα radioactivity, and can be in principle removed by det...
