A refrigerated Dewar for the Josephson array voltage calibration system

Research output: Contribution to journalConference article

Abstract

A refrigerated Dewar has been used successfully with the Josephson array voltage calibration system to reliquefy helium with no degradation of the calibration system's performance. The design of the Dewar is detailed, and experimental data obtained using it are reported. The independence of the array voltage from temperature has been confirmed to 3 parts in 108 per degree Kelvin using this Dewar.
