TY - JOUR AU - Maezawa, Hiroyuki PY - 2015 DA - 2015// TI - Application of superconducting hot-electron bolometer mixers for terahertz-band astronomy JO - IEICE Trans. Electronics SP - 196 EP - 206 VL - 98 IS - 3 KW - HEB mixer applications KW - HEB applications AB - Recently, a next-generation heterodyne mixer detector - a hot electron bolometer (HEB) mixer employing a superconducting microbridge - has gradually opened up terahertz-band astronomy. The surrounding state-of-the-art technologies including fabrication processes, 4 K cryostats, cryogenic low-noise amplifiers, local oscillator sources, micromachining techniques, and spectrometers, as well as the HEB mixers, have played a valuable role in the development of super-low-noise heterodyne spectroscopy systems for the terahertz band. The current developmental status of terahertz-band HEB mixer receivers and their applications for spectroscopy and astronomy with ground-based, airborne, and satellite telescopes are presented.
