Description
Kinetic Inductance Detector (KID) is an exciting device that promises high sensitivity, large format, and submillimeter waves for X-ray imaging arrangements for astrophysics. The KID consists of a superconductor thin film microwave resonator combined with a transmission line. When energy accumulates, Cooper's pair in superconductor films break, producing a quasi-particle. This change increases the kinetic induction in the resonant circuits and can be monitored by the transmission line. Lumped element KID (LEKID) is applied to CaF2 crystals as a substrate in our experiment. 48Ca is one of the double-beta decay nuclei, and 19F is sensitive to spin-dependent elastic scattering with dark matter. The LEKID on CaF2 can be cooled to 10mK. At this stage, the quality factors of the LEKID are about 400 × 10^3 and measurement for particle detection using 241Am particle irradiation also demonstrated at this low temperature.
