提出了一种以砷化镓（GaAs）作为低温闪烁体的直接探测实验，用于寻找质量范围以下的暗物质。为了高灵敏度地探测闪烁光子，我们正在开发集总元动态电感探测器（LE-KIDs）。我们报道了首次制备铝铌LE-KIDs及其基本性质的测量。我们通过电磁模拟设计了LE-KIDs，并通过光刻技术制作了它们。我们对制作的LE-KIDs进行了评估，并在39个设计共振中检测到36个共振。谐振频率大致位于目标位置，精度为，仿真有效地再现了谐振频率对温度的依赖关系。我们演示了LE-KIDs的光学测量，使用波长与来自GaAs的闪烁光子相匹配的LED，其可以在。
A direct detection experiment with gallium arsenide (GaAs) as a cryogenic scintillator is proposed to search for dark matter in the mass range below. To detect scintillation photons with high sensitivity, we are developing Lumped Element Kinetic Inductance Detectors (LE-KIDs). We report the first fabrication of the aluminum-niobium LE-KIDs and measurements of their basic properties. We designed LE-KIDs by conducting electro-magnetic simulations, and fabricated them via photolithography. We evaluated the fabricated LE-KIDs atand detected 36 resonances out of 39 designed resonances. The resonance frequencies are roughly located at the target locations to an accuracy of, and the simulation effectively reproduced the temperature dependence of the resonance frequency. We demonstrated an optical measurement of the LE-KIDs by using an LED with wavelength that matches that of the scintillation photon from GaAs, which can operate at.
