CALDER (Cryogenic wide-Area Light Detectors with Excellent Resolution) developed high-sensitivity cryogenic light detectors for the identification of rare events in particle physics experiments searching for Majorana neutrinos through the observation of the neutrinoless double beta decay. The detectors are based on superconducting sensors called KIDs (Kinetic Inductance Detectors) and feature fast response time and capability of parallel readout (multiplexing) which make them a promising alternative to present technologies for future experiments. The project was supported by an ERC Starting Grant (contract No. 335359).
