A 77 – 117 GHZ CRYOGENICALLY COOLED RECEIVER FOR RADIOASTRONOMY

A new receiver system was recently installed in a radioastronomy antenna, situated near Coonabarabran, NSW, as part of the Major National Research Facility (MNRF) funded project to extend the frequency coverage of the Australia Telescope National Facility antennas. The cryogenically cooled receiver and the active and waveguide components required to achieve the very wide, 77 to 117 GHz, frequency coverage will be described. An early observation from this receiver system will be presented.
