<p>The thermal loss incurred through a fill and vent conduit of a cryostat is minimized by inclusion therein of a central coaxial member. Thermal energy transfer is desirably promoted by radiation between the interior surface of the fill and vent tube and the central coaxial member by enhancement of the emissivity of the respective facing surfaces. For a tubular central member dual paths to respective pressure relief valves are obtained.</p> |
