Study on the contributions to the CUORE energy spectra

Abstract

Abstract CUORE is a cryogenic experiment searching for the neutrinoless double beta decay of 130Te, and it is located at the underground Gran Sasso National Laboratories in the centre of Italy. With its 988 TeO2 crystals, operating at a base temperature of ~10 mK, CUORE is the first ton-scale and ultra-low background bolometric experiment ever realized for this purpose. There are many phenomena that contribute to the CUORE energy spectra, such as 2vββ decay, cosmic rays and materials and environmental radioactivity: disentangle these contributions is of fundamental importance for a correct interpretation of the results. In this poster, some relevant aspect of the CUORE background study is presented.
