Realization of Submillimeter-Wave Imaging Array with Superconducting Direct Detectors

Abstract Using nine element superconducting direct detectors, or SIS photon detectors, we have fabricated a submillimeter-wave astronomical imaging array for a ground-based submillimeter-wave telescope in Atacama Desert in Chile. We call the observing system SISCAM-9, the superconductive imaging submillimeter-wave camera with nine detector elements. SISCAM-9 is the first astronomical instrument using superconducting direct detectors successfully operated on submillimeter-wave telescope.
