The Receivers of the University of Cologne 3m Radio Telescope
Abstract
The University of Cologne 3 m radio telescope at the Gornergrat Observatory has a surface accuracy of 30 μm (rms). It is therefore useful for frequencies up to about 600 GHz. At present three receivers are available: (1) a cryogenic Schottky-mixer receiver that covers a frequency range of 80-115 GHz, (2) a receiver for the frequency range 125-170 GHz using an SIS mixer, and (3) a cryogenic Schottky-mixer receiver for frequencies around 345 GHz. Receivers for the frequency regions around 230 GHz and 460 GHz are under development.
