Abstract

We evaluated the electrical properties of 37 multifilamentary jointed tapes processed by superconducting joint. In the superconducting joining method. a lap-joint was used. Tapes were selectively etched and exposed superconducting cores of the two tapes were brought into contact with each other and then only the joined region was uniaxially pressed in the range of 1,000 to 2,500 MPa. The current carrying capacity and n-value of the jointed tape were evaluated as a function of uniaxial pressure. The highest current carrying capacity and n-value were obtained to be 58%, 26% for the jointed tape to the tape itself.
