Scientific paper

A 3 m radiotelescope with a surface accuracy of better than 50 microns (rms) is presently being constructed. The telescope will be used mainly for molecular line work, and is expected to be usable to a shortest wavelength of about 0.5 mm. It is being equipped with a cryogenic Schottky barrier mixer, operating initially in the 90 GHz band. A 256 channel (1 MHz / channel) filter spectrometer and high resolution (40 kHz / channel) acousto-optic spectrometer will be used for spectral analysis. The various telescope control functions will be carried out by microprocessors, controlled by a PDP 11/34 computer. The entire system is expected to be in operation early 1983.
