Understanding the contributions to the CUORE background

CUORE is a cryogenic experiment located at the underground Gran Sasso National Laboratories in Italy, and is searching for the neutrinoless double beta decay of 130Te. CUORE operates 988 TeO2 crystals at a base temperature of ∼10mK, and is the first ton-scale and ultra-low background bolometric experiment ever realized for this aim. Different phenomena contribute to the CUORE energy spectra, and their understanding is of fundamental importance for a correct interpretation of the results. In this poster, the main aspects of the CUORE background due to radioactive contaminations will be presented
