CUPID-0: the first array of enriched scintillating bolometers for 0[Formula: see text] decay investigations

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 [Formula: see text] Se neutrinoless double-beta decay ([Formula: see text] ). CUPID-0 aims at measuring a background index in...

Sumario: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 [Formula: see text] Se neutrinoless double-beta decay ([Formula: see text] ). CUPID-0 aims at measuring a background index in the region of interest (RoI) for [Formula: see text] at the level of 10[Formula: see text] counts/(keV kg years), the lowest value ever measured using cryogenic detectors. CUPID-0 operates an array of Zn[Formula: see text] 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.
