Abstract：To propose a domestic liquid helium free DC programmable Josephson voltage standard (PJVS) operating on a cryocooler around 10K. The design and structure of the cryogenic system of liquid helium free quantum voltage standard are presented. The structure of NMIJ array at around 10K temperature are analyzed in detail. The experimental results show that the liquid helium free quantum voltage standard cryogenic system can provide stable temperature for NMIJ Josephson junction array, and the measured critical current and the quantum voltage step width meet the requirements of superconducting characteristics of the junction array. The research lays an important foundation for the accurate liquid helium free DC quantum voltage output in the next step.
