Development of superconducting mixers and detectors for THz astronomy

摘要

The terahertz (THz) and FIR band is a frequency regime to be fully explored in astronomy. Dome A in Antarctic offers the best possible access for ground-based astronomical observations in this unique frequency regime. In this paper Fourier transform spectrometer (FTS) measurement of THz atmospheric transmission from Dome A is introduced and superconducting mixers and detectors developed for a THz telescope named DATE5 are presented.
