Description |
The Cryogenic Underground Observatory for Rare Events (CUORE) will search for the 0νββ decay in 130Te using a cryogenic array of TeO2 bolometers, operated at a base temperature of ~10 mK. CUORE will consist of a closely packed array of 19 towers each containing 52 crystals, for a total mass of 741 kg. With a background goal of 10 c/keV/ton/y and an expected energy resolution of ~5 keV in the region of interest, CUORE has the potential to probe the effective Majorana neutrino mass down to 50-130 meV (90% C.L). The detector assembly is hosted in one of the largest cryostats ever constructed and will be cooled down to base temperature using a custom-built cryogen free dilution refrigerator. The detector and the cryostat are in an advanced stage of installation and is expected to start operation by the end of 2015. After briefly reviewing results from a neutrinoless double-beta decay search with CUORE-0, I will outline the design of the CUORE cryostat, its performance during the integration runs and the present construction status of the experiment.
