  Title A low temperature bolometer heterodyne receiver for Millimeter wave astronomy Type Journal Article
  Year 1973 Publication Rev. Sci. Instrum. Abbreviated Journal Rev. Sci. Instrum.  
  Volume 44 Issue 8 Pages 1009-1014  
  Keywords InSb HEB mixer  
  Abstract Liquid helium cooled InSb hot electronbolometers are used in a balanced mixer configuration as detectors for an imagelessmicrowave receiver. The system is designed for mounting at the prime focus of the National Radio Astronomy Observatory (NRAO) 11 m antenna at Kitt Peak, Arizona, and is suitable for the study of rotational line spectra of interstellar gas molecules. Currently the operating frequency is in the 90–140 GHz band where the double sideband system noise temperature is 250 K.
