Beam-combining superconducting detector for submillimetre-wave astronomical interferometry

摘要

The feasibility of making single-chip, superconducting detectors for submillimetre-wave astronomical inteferometry is demonstrated. An experimental device based on back-to-back corrugated horns, and back-to-back finline transitions, was fabricated. The detector was illuminated at 350 GHz, using a coherent laboratory source, and 0.6/spl deg/ fringes were measured.
