- Abstract:
- A 10 V DC quantum voltage calibration system, based on a programmable Josephson voltage standard (PJVS) operating in liquid helium, has been recently set-up and tested at INRiM. The PJVS system is partly-commercial and is based on a 10 V superconductor-normal metal-superconductor (SNS) array of 69631 Josephson junctions operated on the first Shapiro steps. The goal is to establish a new highreliability quantum voltage standard for the DC calibration of solid-state voltage sources and digital voltmeters (DVMs). The paper reports the PJVS system description and first experimental testings and calibrations, preparatory to the future participation to international comparisons as final validation of the novel system.
