Terahertz Detector Development (D03)

点击翻译按钮获取中文摘要

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.
