Description
The development of large area cryogenic light detectors is one of the priorities of next generation bolometric experiments searching for Majorana neutrinos. The simultaneous read-out of the heat and light signals enables particle identification, provided that the energy resolution and the light collection are sufficiently high. CALDER (Cryogenic wide-Area Light Detectors with Excellent Resolution) is developing phonon-mediated silicon light detectors using kinetic inductance detectors (KIDs), with the goal of sensing an area of 5x5 cm$^2$ with an energy resolution of ~ 20 eV RMS. I will present the latest results obtained with aluminum chips and with newly developed multilayer titanium-aluminum chips featuring unprecedented sensitivity.
Work based on arXiv:1801.08403 and given on behalf of the CALDER collaboration.
