Terahertz Detector Development (D03)

我们开发了用于天文学的非常灵敏的超导探测器：超导绝缘体超导体(SIS)隧道结、超导热电子测辐射热计(HEB)和微波动力学电感探测器(MKID)。SIS和HEB是为用于极高分辨率太赫兹外差光谱的平衡和边带分离混频器而开发的。MKID将成为相机的一部分，达到地面操作的背景有限灵敏度。复杂的片上电路在超薄硅衬底上内部制造，并集成到我们内部车间制造的精密外壳中。探测器将用于CCAT PRIME望远镜和索非亚天文台的接收器。

We develop very sensitive superconducting detectors for astronomy: Superconductor Insulator Superconductor (SIS) tunnel junctions, superconducting Hot Electron Bolometers (HEB) and Microwave Kinetic Inductor Detectors (MKID). SIS and HEB are developed for balanced and side band separating mixers for very high resolution THz heterodyne spectroscopy. MKIDs will be part of a camera, reaching background limited sensitivity for ground-based operation. The complex on-chip circuits are fabricated in house on ultra-thin silicon substrates and integrated into precision-housing, made in our in-house workshop. Detectors will be applied in receivers for the CCAT prime telescope and for the SOFIA observatory.
