项目摘要

The Cardiff Astronomy Instrumentation Group (AIG) is one of the world leaders in Kinetic Inductance Detector (KID) development. These superconducting detectors are the most promising technology for the next generation of millimeter - THz wave detectors. Along with ultra-high sensitivity, theses detectors can be multiplexed into large format arrays allowing as many as 10'000 detectors to be read out on a single channel making them suitable for a range of ground and space-based applications. Along with our collaborators, Cardiff has proven this technology for photometric applications on ground-based telescopes and industrial THz imaging systems.The next natural progression of KID technology is to incorporate the detector architecture into filtering structures allowing the realization of multi-chroic pixels and on-chip spectroscopy. This development would drastically simplify the components required to create spectral imaging systems required for the next generation of ground and space-based observatories.Working with our collaborators and as part of our on-going funded research in detector development, the objectives of this project will be to study the device physics of both the KID and planar filtering structures in order to build and test devices suitable for astronomical observation in the mm and submm wavebands. Students can expect to learn a variety of skills including: Cryogenics, superconductivity theory and application, detector design and testing, microwave design using industry standard 2D and 3D modelling software and device fabrication.

卡迪夫天文仪器集团（AIG）是动力学电感探测器（KID）开发领域的世界领导者之一。这些超导探测器是下一代毫米太赫兹波探测器最有前途的技术。沿着超高灵敏度，这些探测器可以被多路复用成大格式阵列，允许在单个通道上读出多达10'000个探测器，使它们适合于一系列地面和空间应用。沿着我们的合作者，卡迪夫已经证明了这项技术在地面望远镜和工业太赫兹成像系统上的光度应用。KID技术的下一个自然发展是将探测器架构纳入滤波结构，从而实现多色像素和片上光谱。这一发展将大大简化创建下一代地面和空间观测站所需的光谱成像系统所需的组件。与我们的合作者一起工作，作为我们正在进行的探测器开发资助研究的一部分，这个项目的目标是研究KID和平面滤波结构的器件物理学，以便制造和测试适合于天文观测的器件在毫米和亚毫米波段。学生可以期望学习各种技能，包括：低温学，超导理论和应用，探测器设计和测试，使用行业标准的2D和3D建模软件和设备制造的微波设计。
