We have demonstrated a combined test of the submillimeter-wave SIS photon detectors and GaAs-JFET cryogenic integrated circuits. A relatively large background photo-current can be read out by fast-reset integrating amplifiers. An integration time of 1 ms enables fast frame rate readout and large dynamic range imaging, with an expected dynamic range of 8,000 in 1 ms. Ultimate fast and high dynamic...
We are developing submillimeter-wave imaging array using superconducting SIS photon detectors, under collaboration between NAOJ, RIKEN and NICT. We named the imaging array as superconductive imaging submillimeter-wave camera (SISCAM). In this paper optical design and cold readout electronics of SISCAM are discribed. Optical design is based on lens array with planar antenna for each detector pixel...
