Description

CaF2 is a novel target for neutrino-less double-beta decay and spin-dependent dark matter studies, since 48Ca is one of the double-beta decay nuclei and 19F is sensitive to spin-dependent elastic scattering with dark matter.
We implement kinetic inductance detectors(KIDs) on CaF2 crystal which is used as substrate. KIDs on CaF2 is cooled to low temperature with a dilution fridge. The resonance is found in O(1GHz). In addition, several basic parameters of KIDs are measured. Thus, we confirmed that KIDs on CaF2 worked well. This result opens a new possibility in the next generation of astroparticle physics experiments.
