The object of this Phase II program is to fabricate and test                    novel cryogenic composites designed for use as regenerators in                  closed-cycle cryocoolers operating below 10 K.  The material is a               composite of helium self-loaded into a metallic extended surface                structure whose dispersion form is suitable for the thermal flux                and frequency requirements of regenerators.  High effective heat                capacity from 3 - 6 K derives from the latent heat of                           vaporization and condensation of subcritical helium, and high                   heat capacity below 10 K derives from the sensible heat capacity                of pressurized helium.  High, anisotropic thermal conductivity in               the regenerator derives from the geometric form of the metallic                 component.  The combination of high heat capacity and high radial               thermal conductivity allows for rapid thermal penetration and                   high regenerator effectiveness.  The potential exists to achieve                significant refrigeration power at liquid helium temperatures                   with a closed-cycle cryocooler not involving a Joule-Thomson gas-               Throttling stage.
