Scientific paper

Design of a dual-polarization InSb hot-electron bolometer-mixer receiver that has been built for the James Clerk Maxwell Telescope is described. The receiver designed as a 'common-user' or facility instrument operates at 461 - 492 GHz. Receiver noise temperatures of 500 K have been obtained at 461 GHz, in observing bandwidth of 3 MHz. InSb receivers are considered to be competitive with the current generation of Schottky receivers as the maximum resolution bandwidth is in fact well matched to the width of the lines being observed.
