Paper Abstract

A superconducting (SIS) tunnel junction heterodyne receiver has been constructed and tested over the frequency range450 to 540 GHz. The receiver uses a reduced height waveguide mount and a Pb alloy tunnel junction as the detectingelement. Performance measurements made with the receiver installed on the James Clerk Maxwell Telescope, Hawaii,show a noise temperature (DSB) of 165 K at 460 GHz and 220 K at 490 GHz, measured in a 1 GHz instantaneous IFbandwidth centred at 4 GHz. The receiver demonstrates that Pb alloy junctions are sufficiently stable and reliable toallow use at a remote observing site at sub-millimetre wavelengths.
