摘要
The development and fabrication of a layer-wound, epoxy-impregnated Bi-2223 high-temperature superconducting (HTS) racetrack coil which generates 40,000 ampere-turns of magnetomotive force (MMF) at 25K is described, The coil was wound using Ag-sheathed Bi-2223 tape conductor laminated with copper foils for strength enhancement and insulated using a paper-wrap method, After epoxy impregnation, the coil was tested over a range of 16-25K in a vacuum dewar using a closed-cycle helium refrigeration system, Descriptions of the tape lamination and insulation processing, the coil winding and impregnation, and the experimental test setup are given.
