Summary

A 2.5 T/100 kilovoltampere alternating-current superconducting magnet has been developed to demonstrate the advantages of using a high-critical current density superconducting wire and the validity of the pin-design method. The magnet was operated at 4.2 K and 60 hertz, reaching the electrical capacity of 104.8 kilovoltamperes. The total alternating-current losses in operating at the central magnetic field of 2 T were extremely small, about 4.8 W which was 0.007% of the electrical capacity.
