Patent ID: 7451719

Claim:
A light-weight reduced-size degaussing system comprising: a water vessel having three perpendicular vessel planes; a plurality of degaussing coil loops running throughout a hull of the water vessel, with a plurality of said plurality of degaussing coil loops arranged substantially parallel to each of said three perpendicular vessel planes, wherein each degaussing coil loop comprises a light-weight reduced-size cable assembly, each cable assembly comprising: a hollow support tube; a high temperature superconductor cable wrapped around the hollow support tube, the support tube supporting the high temperature superconductor cable; a single-phase gaseous cryogen flowing through the hollow support tube for cooling the high temperature superconductor; a cryogenic tube with an elongated opening, wherein the high temperature cable and the hollow support tube are located within the elongated opening of the cryogenic tube; one or more power sources electrically connected to said plurality of degaussing coil loops for providing electric currents through said degaussing coil loops; one or more circulation fans associated with each cable assembly for circulating the single-phase gaseous cryogen; and one or more refrigerators associated with each cable assembly for receiving and cooling the single-phase gaseous cryogen circulated by said one or more circulation fans, wherein the force of the fan directs the cooled single-phase gaseous cryogen from the refrigerator to and through the hollow tube.
