A refrigerated Dewar for the Josephson array voltage calibration system
A refrigerated Dewar has been used successfully with the Josephson array voltage calibration system. It has been used to re-liquefy helium with no degradation of the calibration system's performance. The independence of the array voltage from temperature has been confirmed to three parts in 10{sup 8} per Kelvin using this Dewar. 6 refs., 3 figs.
