Abstract :
A 240-mm-bore high-field superconducting coil was designed, fabricated, and tested. This coil is planned as a test facility for the development of large-scale superconductors for fusion machines. Tests were performed in a 4.2 K bath, and the designed magnetic flux density of 13.0 T was obtained in the center of its bore. The maximum magnetic flux density on the coil was 13.9 T; the average current density was 101 A/mm2; the stored energy was 4.8 MJ; and the charging time was 18.5 minutes. This coil has served as a reliable conductor test facility since the first achievement of 13.0 T
