Cryogenic wide-Area Light Detectors with Excellent Resolution

The CALDER project is supported by an Italian grant for fundamental research (FIRB) and by an ERC Starting Grant. Its goal is to develop high sensitivity cryogenic light detectors based on kinetic inductance detectors (KID). First proposed for astrophysical applications, KIDs demonstrated a great potential in this field. They could also be used in bolometric experiments searching for neutrinoless double beta decay and dark matter. In these experiments the double readout of the heat and light signals allows to discriminate between different kinds of particles, leading to a reduction of the background and to an increase of the experimental sensitivity. The research project is organized in two branches, one consisting in the development of the light detectors while the other in the realization of a large scale readout system that would be needed when equipping large mass bolometric experiments. The Genova group is involved in the development of the CALDER readout system and in data analysis.
