Abstract

The paper deals with recent progress at INRiM towards the setting up and preliminary characterization of a novel programmable Josephson voltage standard (PJVS) operating in a small liquid helium dewar. The PJVS setup is based on a 1-V superconductor-normal metal-superconductor (SNS) binary-divided array of 8192 Josephson junctions. To ensure proper operating conditions of the PJVS chip a custom short cryoprobe was designed, built and successfully tested. The overall system is being developed in the framework of EMPIR project 19RPT01-QuantumPower. The goal is to establish a new quantum voltage standard for sampled power measurement and to gain confidence in running quantum voltage standards for precise calibration of digital sampling multimeters and arbitrary waveform digitizers used in the ac-voltage and power metrology community.
