Development of HTS coil with Bi-2223 transposed segment conductor

Bi₂Sr₂Ca₂Cu₃O_x (hereinafter referred as Bi-2223) transposed segment conductors were developed for high-T_c superconducting power cables. As the conductors have good mechanical, electrical and thermal properties, the conductor has applicability for other application. So, we have been developing a solenoid coil with Bi-2223 transposed segment conductor. The fabricated coil with the conductor was demonstrated successfully to transport AC current. The performance test results indicate that the conductor is suitable for the coils of pulse or AC application, especially SMES coils.
