We have successfully operated a Josephson voltage standard (JVS) with a superconducting shield in a magnetic-field environment. This study involves mounting a NbN-based JVS chip on a custom-made 12 K ...

This paper develops a system using the zero-compensation (ZC) Josephson arbitrary waveform synthesizer (JAWS) to measure an ac power of 220 V, 5 A, 60 Hz and power factor of 1.0. In the structure, an ...
