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 three parts in 10/sup 8/ per degree Kelvin using this Dewar.<>
