CALDER: neutrinoless double-beta decay identification in TeO2 bolometers with kinetic inductance detectors

Next-generation experiments searching for neutrinoless double-beta decay must be sensitive to a Majorana neutrino mass as low as 10 meV. CUORE, an array of 988 TeO2 bolometers being commissioned at Laboratori Nazionali del Gran Sasso, features an expected sensitivity of 50130 meV at 90 % C.L. The background is expected to be dominated bya radioactivity, and can be in principle removed by detecting the small amount of Cherenkov light emitted by the beta signal. The Cryogenic wide-Area Light Detectors with Excellent Resolution project aims at developing a small prototype experiment consisting of TeO2 bolometers coupled to high-sensitivity light detectors based on kinetic inductance detectors. The R& D is focused on the light detectors in view of the implementation in a next-generation neutrinoless double-beta decay experiment.
