Development of Microstrip-Coupled Lumped-Element Kinetic Inductance Detectors for Astronomy

该项目旨在开发超导天线和平面滤波结构，用于未来宇宙微波背景实验中使用的动力学电感探测器的光学耦合。这一领域的发展将允许单个像素检测和分离两种偏振中几种不同频率的光，大大简化和减少焦平面的体积，从而实现更便宜，更紧凑的仪器，而不会影响性能。该项目包括研究射频频率下的超导电动力学、制造工艺以及探测器设计和制造。我们与剑桥大学的合作伙伴合作开展工作。

This project aims to develop superconducting antennas and planar filtering structures for optical coupling to kinetic inductance detectors for use in future Cosmic Microwave Background (CMB) experiments. Development in this area will allow a single pixel to detect and separate light from several different frequencies in two polarisations, drastically simplifying and reducing the volume of focal planes allowing cheaper and more compact instruments to be realised without a compromise on performance. The project comprises research into superconductor electrodynamics at RF frequencies, fabrication processes and detector design and fabrication. Work is carried out in collaboration with our partners at Cambridge University.
