Abstract

A new 790 – 940 GHz heterodyne receiver, ASTE Band 10, was installed in October 2019 on ASTE (Atacama Submillimeter Telescope Experiment), a 10 m submillimeter telescope near of the ALMA site in Chile. An ALMA Band 10 prototype receiver was upgraded with SIS mixers employing high-Jc junctions. The receiver noise temperature (TDSB) measured in the laboratory is between 175 K and 344 K. The achieved system noise temperature on ASTE toward the zenith was 2400 K (PWV <1.0 mm). Their Allan variances were less than 2.0 x 10^-6for timescales in the range of 0.05 sec < T <100 sec.
