Description
CUPID-0 is the first large array of enriched scintillating ZnSe cryogenic calorimeters implementing active particle identification. The detector consists of an array of 24 ZnSe crystals enriched in $^{82}$Se and two natural ZnSe crystals for a total mass of 10.5 kg installed in a dilution refrigerator hosted at the Laboratori Nazionali del Gran Sasso.
The heat-light readout exploited in CUPID-0 provides a unique tool for $\alpha$-particle discrimination and allows to suppress the background in the region of interest to an unprecedented level for a bolometric experiment. We will report the first results of the search for neutrinoless double beta decay ($0\nu\beta\beta$) in $^{82}$Se and a preliminary background reconstruction.
