动力学电感探测器（KID）是一种具有高灵敏度的大尺寸阵列探测器，可以探测从亚毫米波到伽马射线的光子。KID由超导薄膜微波谐振器和传输线组成。当能量累积时，超导膜中的库珀对被破坏。于是准粒子产生了。这种变化增加了谐振电路中的动态电感，并且可以通过传输线进行监测。我们建议，集总元件KID（LEKID）的氟化钙（CaF2）基板上实施的下一代天体粒子实验。48Ca是双β衰变核之一，19F对暗物质的自旋相关弹性散射敏感。CaF2上的LEKID可以使用稀释制冷机冷却到15mK。在此阶段，LEKID的品质因数约为500× 103，并在此低温下使用241 Am粒子照射进行粒子探测测量。
Kinetic Inductance Detector (KID) is an exciting device that promises high sensitivity to photons from submillimeter waves to gamma-rays with large format arrays. The KID consists of a superconductor thin film microwave resonator combined with a transmission line. When energy accumulates, Cooper pairs in the superconductor films are broken. Then quasiparticles are produced. This change increases the kinetic inductance in the resonant circuits and can be monitored by the transmission line. We propose that Lumped Element KID (LEKID) is implemented on Calcium Fluoride (CaF2) substrate for next-generation astroparticle experiments. 48Ca is one of the double-beta decay nuclei, and 19F is sensitive to spin-dependent elastic scattering with dark matter. The LEKID on CaF 2 can be cooled to 15mK using a dilution refrigerator. At this stage, the quality factors of the LEKID are about 500× 10 3, and measurement for particle detection using 241Am particle irradiation is also demonstrated at this low temperature.
