Energy resolution and efficiency of phonon-mediated Kinetic Inductance Detectors for light detection

Abstract

The development of sensitive cryogenic light detectors is of primary interest for bolometric experiments searching for rare events like dark matter interactions or neutrino-less double beta decay. Thanks to their good energy resolution and the natural multiplexed read-out, Kinetic Inductance Detectors (KIDs) are particularly suitable for this purpose. To efficiently couple KIDs-based light detectors to the large crystals used by the most advanced bolometric detectors, active surfaces of several cm${}^2$ are needed. For this reason, we are developing phonon-mediated detectors. In this paper we present the results obtained with a prototype consisting of four 40 nm thick aluminum resonators patterned on a 2$\times$2 cm${}^2$ silicon chip, and calibrated with optical pulses and X-rays. The detector features a noise resolution ${\sigma }_E=154\pm 7$ eV and an (18$\pm$2)$\%$ efficiency.
