Abstract
A low-cost, low maintenance helium circulator will be designed and demonstrated for use in High Temperature Superconducting (HTS) systems. The circulator design will feature an oil-free high-speed fan supported on foil gas bearings. The basis for this design has been extensively used and demonstrated by R&D Dynamics in other applications e.g. fuel cells, at very high temperatures, up to 700 deg. C. In Phase I the feasibility was demonstrated. In Phase II a working prototype will be designed, built and laboratory tested. In Phase III a full scale prototype will be installed onboard a Navy ship for extended testing.
