CUORE Spectrum and Background

The Cryogenic Underground Observatory for Rare Events (CUORE) is a neutrinoless double-beta decay experiment at the Laboratori Nazionali del Gran Sasso (LNGS). CUORE is performing this search in $^{\mathrm{130}}$Te by using 988 TeO$_{\mathrm{2}}$ bolometric crystals arranged in 19 towers inside of a cryostat operating below 20 mK. In this talk, I will discuss the measured background in the CUORE experiment and simulations of the background model, critical parts leading towards a measurement of two-neutrino double-beta decay.
