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

本项目旨在为未来宇宙微波背景（CMB）实验开发超导天线和平面滤波结构，用于与动力电感探测器的光学耦合。该领域的发展将允许单个像素在两个偏振中检测和分离来自几个不同频率的光，大大简化和减少焦平面的体积，从而在不影响性能的情况下实现更便宜和更紧凑的仪器。该项目包括射频超导体电动力学的研究、制造工艺和探测器的设计和制造。这项工作是与我们在剑桥大学的合作伙伴合作进行的。

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.
