JOSEPHSON VOLTAGE STANDARD INTERCOMPARISON

Abstract
The majority of Josephson Voltage Standard (JVS) intercomparisons have been performed by using Zener voltage transfer standards and a protocol based on the Measurement Assurance Program (MAP) with uncertainties in the range of a few parts in 10^8 at 10 V that are limited by the Zener characteristics. In order to improve the uncertainty of the comparison, protocols using a compact Josephson voltage standard (CJVS) as the transfer standard have been developed. The uncertainty using the CJVS in the comparison can be in the range of a few parts in 10^9 at 10 V. The array to array direct comparison using the conventional JVS or programmable JVS (PJVS) can further improve the uncertainty of the comparison to a few parts in 10^10.Proceedings Title
