The Development of an Interferometer for Millimeter Wavelengths.

Abstract

The report describes the development of an interferometer to operate at millimeter wavelengths. The two elements are the 20-foot millimeter antenna at the Hat Creek Observatory and the 10-foot dish that had been in use for millimeter work previously. The antenna separation is fixed at about 260 meters. The report describes the development of all the various components for the interferometer. These include: (a) the front end for the 10-foot dish, (b) the IF amplifiers, (c) the line equalizers, (d) the variable delay line, (e) the wide-band correlator, (f) the local oscillator system, (g) the multichannel spectrometer, (h) the digital components and computer interface, and (i) the computer control program. In addition, results are given for preliminary observations of the planet Venus and the quasar 3C84. (Author)
