Abstract
Next-generation experiments searching for neutrinoless double-beta decay must be sensitive to a Majorana neutrino mass as low as 10$$\mathrm {~meV}$$meV. CUORE , an array of 988 TeO$$_2$$2 bolometers being commissioned at Laboratori Nazionali del Gran Sasso, features an expected sensitivity of 50-130$$\mathrm {~meV}$$meV at 90 % C.L. The background is expected to be dominated by $$\alpha $$? 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 TeO$$_2$$2 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
