CUORE-0 is a cryogenic detector that uses an array of tellurium dioxide bolometers to search for neutrinoless double-beta decay of \(\mathrm {^{130}Te}\) . We present the first data analysis with \(7.1 \,\mathrm {kg\cdot y}\) of total \(\mathrm {TeO_2}\) exposure focusing on background measurements and energy resolution. The background rates in the neutrinoless double-beta decay region of interest (2.47 to \(2.57 \,\mathrm {MeV}\) ) and in the \(\alpha \) background-dominated region (2.70 to \(3.90\,\mathrm {MeV}\) ) have been measured to be \({0.071\pm 0.011}\) and \({0.019\pm 0.002}\,\mathrm {counts/(keV\cdot kg\cdot y)}\) , respectively. The latter result represents a factor of 6 improvement from a predecessor experiment, Cuoricino. The results verify our understanding of the background sources in CUORE-0, which is the basis of extrapolations to the full CUORE detector. The obtained energy resolution (full width at half maximum) in the region of interest is \(5.7\,\mathrm {keV}\) . Based on the measured background rate and energy resolution in the region of interest, CUORE-0 half-life sensitivity is expected to surpass the observed lower bound of Cuoricino with one year of live time.
