Abstract

Summary form only given, as follows.Summary form only given. The Australian voltage standard uses a 1 V Josephson junction array fabricated by NIST and excited at 73 GHz. The entire system is described, including: the liquid-helium dewar designed to permit permanent immersion of the array, the array bias circuitry, the Gunn-diode driver circuitry, the system of low-thermal key-switches, and other techniques of minimising small errors and interference. The effect of various guard and ground connections to secondary electronic standards is described. A complete Type A and Type B uncertainty analysis of the system is given.
