초록 ▼

A transmission line using superconductors instead of conventional conductors substantially reduces ohmic losses compared to conventional conductors. The superconductors are cooled by refrigerant flowing through a hollow superconducting inner conductor. The refrigerant is transported to the inner con

대표청구항 ▼

A connector, electrically and mechanically coupling and thermally isolating a first high-temperature coaxial cable from a second low temperature coaxial cable, said first high-temperature coaxial cable having at least inner and outer conductors and being a nonsuperconducting cable and said second low temperature coaxial cable having at least inner and outer conductors, at least one of said inner and outer conductors of said second cable being superconductors that require thermal isolation from relatively high temperature bodies, said connector comprising: first connector half having a hollow outer conductor with a first inner diameter and having at least a hollow superconducting center conductor, a portion of said superconducting center conductor having a second predetermined outer diameter dimension and having a third inner diameter dimension, said center conductor of said first connector half being capable of conducting refrigerant there through, said center conductor of said first connector half being coupled to the inner conductor of said second low temperature coaxial cable and said outer conductor of said first conductor half being coupled to the outer conductor of said second low temperature coaxial cable; second connector half having a hollow outer conductor having a first outer diameter less than said first inner diameter of said outer conductor of said first connector half, and having a center conductor at least a predetermined length of which is hollow, said hollow length with a predetermined inner diameter greater than the outer diameter of said superconducting center conductor of said first connector half and having an exit port means extending from said hollow portion of said center conductor through the outer conductor of said second connector half, said exit port means for conducting refrigerant from said hollow superconducting center conductor of said first connector half when said first and second connector halves are joined together, said center conductor of said second connector half being coupled to the inner conductor of said first high-temperature coaxial cable and said outer conductor of said second conductor half being coupled to the outer conductor of said first high-temperature coaxial cable; first capacitive coupling means for mechanically and capacitively coupling and thermally isolating the inner conductors of said first and second cables, said first capacitive coupling means being a dielectirc occupying a volume defined between the outer diameter of said center conductor of said first connector half and the inner diameter of said center conductor of said second connector half; second capacitive coupling means for mechanically and capacitively coupling and thermally isolating the outer conductors of said first and second cables, said second capacitive coupling means being a dielectric occupying a volume between the outer diameter of said outer conductor of said second connector half and the inner diameter of said outer conductor of said first connector half said second capacitive coupling means displaced from the first capacitive coupling means by a distance approximately equal to an integral number of one-quarter wave lengths of a signal propagating through said coaxial cables.
