Abstract

Superconducting microwave microresonators are low temperature detectors (LTDs) suitable for large-scale frequency domain multiplexing readout. A promising approach consists in operating the resonators in quasi-thermal equilibrium mode: the resonator acts as a thermometer sensing the temperature rise of an absorbing material caused by an energy release. Our aim is to develop such detectors to perform spectroscopy in the keV range, with a possible future application to a next generation experiment aimed at directly measuring the neutrino mass. Still, the best configuration in terms of detector design and material must be found. Resonators made of several Ti/TiN multilayer films, which is a high kinetic inductance superconducting material previously developed by our group, were recently produced. The resonators are deposited onto a silicon slab and the sensitive area, thermally coupled to a gold absorber, is kept suspended by means of a SiN membrane. In this way we plan to exploit the excellent energy resolution of LTDs combined with the simple multiplexing scheme of the resonators. In this contribution we present the devices along with our project, with its status and perspectives
