Abstract :
We report here on a 176-256 GHz low-noise receiver system recently installed in the first of our submillimeter array antennas. The receiver is housed in a cryostat cooled by a closed-cycle helium refrigerator and has a double-side-band receiver noise temperature of about 60 K across the entire input frequency range and an instantaneous bandwidth of 2.5 GHz
