Abstract
We describe a Pb alloy superconducting (SIS) tunnel junction heterodyne receiver that has been constructed and tested over the frequency range 450 to 540 GHz and installed on the James Clerk Maxwell Telescope, Hawaii. The receiver uses a reduced height waveguide mount and a Pb alloy tunnel junction as the detecting element. Performance measurements made with the receiver installed on the telescope show a noise temperature (DSB) of 165 K at 460 GHz and 220 K at 490 GHz, measured in a 1 GHz instantaneous IF bandwidth centred at 4 GHz. The receiver demonstrates that Pb alloy junctions are sufficiently stable and reliable to allow use at a remote observing site at sub-millimetre wavelengths.
