Use of the Josephoson Junction Array Voltage Standard in Industry

Abstract
A novel trial for use of a fully automated Josephson-junction-array-voltage-standard (JJAVS) system in industry has been carried out since January 1991. Long-term performance tests show that the JJAVS system is available as an industrial-use voltage standard with an accuracy of 0.01 ppm as well as for use in the national laboratory.
