Abstract
With their excellent energy resolution, efficiency, and intrinsic radio-purity, cryogenic calorime- ters are primed for the search for neutrino-less Double Beta Decay (0νDBD). The sensitivity of these devices could be further increased by discriminating the dominant α background from the expected β like signal. The CUPID-0 experiment aims at demonstrating that the measurement of the scintillation light produced by the absorber crystals allows for particle identification and, thus, for a complete rejection of the α background. The CUPID-0 detector, assembled in 2016 and now in commis- sioning phace, consists of 26 Zn(82)Se scintillating calorimeters for about 2·10^25 0νDBD emitters. Here we present the preliminary results obtained with the detector and the perspectives for a next generation project.
