CUORE crystal validation runs: Results on radioactive contamination and extrapolation to CUORE background
The CUORE Crystal Validation Runs (CCVRs) have been carried out since the end of 2008 at the Gran Sasso National Laboratories, in order to test the performance and the radiopurity of the TeO2 crystals produced at SICCAS (Shanghai Institute of Ceramics, Chinese Academy of Sciences) for the CUORE experiment. In this work the results of the first 5 validation runs are presented. Results have been ...
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...
متن کاملPotential 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...
