Background suppression plays a crucial role in particle physics experiments searching for rare events, such as neutrinoless double beta decay and dark matter interactions. Bolometers, that are among the most competitive devices in this field, would largely benefit from the development of ultrasensitive light detectors, as the combined readout...

The main aim of the cryogenic wide-area light detectors with excellent resolution project is the development of cryogenic light detectors with large active area (∼50 mm × 50 mm) and noise energy resolution smaller than 20-eV RMS. Such detectors will be used to discriminate the background in next generation large-mass bolometric experiments,...

CUPID-0 is the first large mass experiment based on cryogenic calorimeters (bolometers) that implements the dual read-out of light and heat for background rejection. The detector, consisting of 24 enriched Zn82Se crystals (5.28 kg of 82Se), is taking data in the underground LNGS (Italy) from March 2017. In this contribution we present the...

CUPID-0 is the first large array of scintillating Zn82Se cryogenic calorimeters (bolometers) implementing particle identification for the search of the neutrinoless double beta decay (0nbb). The detector consists of 24 enriched Zn82Se bolometers for a total 82Se mass of 5.28 kg and it has been taking data in the underground LNGS (Italy) since...
