We propose the utilization of inorganic crystals as substrates for kinetic inductance detectors (KIDs), which are thin-film superconducting resonators, for future rare event studies. When energy is deposited on the substrate, phonons are generated and propagate from the substrate to the surface, where KIDs are fabricated. This approach expands the potential for utilizing a diverse range of target crystals. We implement KIDs on calcium fluoride (Ca[F.sub.2]) substrates, since [.sup.19]F is sensitive to dark matter with spin-dependent interaction and [.sup.48]Ca is one of the double-[beta] decay nuclei. We have experimentally demonstrated the operation of the KIDs on the Ca[F.sub.2] substrate and their phonon-mediated particle detection. Subject Index H20
1. Introduction The quest to discover rare events such as dark matter and neutrinoless double beta (0v[beta][beta]) decay in underground laboratories represents a significant frontier in astroparticle physics. In the [...]
