Abstract

International audience; The CUPID-0 experiment searches for double beta decay using cryogenic calorimeters with double (heat and light) read-out. The detector, consisting of 24 ZnSe crystals 95 $\%$ enriched in$^{82}$ Se and two natural ZnSe crystals, started data-taking in 2017 at Laboratori Nazionali del Gran Sasso. We present the search for the neutrino-less double beta decay of$^{82}$ Se into the 0$_1^+$ , 2$_1^+$ and 2$_2^+$ excited states of$^{82}$ Kr with an exposure of 5.74 kg $\cdot $ yr (2.24 $\times $ 10$^{25}$ emitters $\cdot $ yr). We found no evidence of the decays and set the most stringent limits on the widths of these processes: $\varGamma $ ($^{82}$ Se $\rightarrow ^{82}$ Kr$_{0_1^+}$ )8.55 $\times $ 10$^{-24}$ yr$^{-1}$ , $\varGamma $ ($^{82}$ Se $\rightarrow ^{82}$ Kr$_{2_1^+}$ ) $\,{

Abstract

International audience; The CUPID-0 detector hosted at the Laboratori Nazionali del Gran Sasso, Italy, is the first large array of enriched scintillating cryogenic detectors for the investigation of$^{82}$ Se neutrinoless double-beta decay ( $0\nu \beta \beta $ ). CUPID-0 aims at measuring a background index in the region of interest (RoI) for $0\nu \beta \beta $ at the level of 10$^{-3}$ counts/(keV kg years), the lowest value ever measured using cryogenic detectors. CUPID-0 operates an array of Zn$^{82}$ Se scintillating bolometers coupled with bolometric light detectors, with a state of the art technology for background suppression and thorough protocols and procedures for the detector preparation and construction. In this paper, the different phases of the detector design and construction will be presented, from the material selection (for the absorber production) to the new and innovative detector structure. The successful construction of the detector lead to promising preliminary detector performance which is discussed here.

Abstract

International audience; CUPID-0 is an array of 24 Zn82Se scintillating bolometers used to search for the 0νββ decay of 82Se. It is the first large mass 0νββ experiment exploiting a double read-out technique: the phonon signal to accurately measure particle energies and the light signal to reject the α-induced background. Its success might open the road to a next generation project of ton mass scale, CUPID. The array is in operation at Laboratori Nazionali del Gran Sasso since the beginning of 2017, in this paper we present the preliminary results obtained with an exposure of 10.45 kg· y.
