Abstract:

This report describes the construction of a 345 Gigahertz receiver system based on superconducting tunnel junctions. The junctions used are Niobium edge junctions, which are mounted in a waveguide mixer mount. Highest sensitivity occurs at 312 GHz with a measured receiver noise temperature of 275 K double sideband. Theoretical calculations and experimental results both indicate the likelihood of good low noise operation out to 1000 GHz using techniques of the sort described here.
