✦ Synopsis

The development work of the high-performance Nb 3 Sn superconducting strand for the Center Solenoid Coil, a high-field large pulse coil, of the International Thermonuclear Experimental Reactor (ITER) have been progressed by Japan Atomic Energy Research Institute with Japanese wire and cable companies° The main.required performances for the 0.8 mm-diameter chromium plated strand were 550 A/mm 2 or higher as the critical current density at 12 T and 200 mJ/cm 3 or lower as the hysteresis loss for ±3T. As the result of research and development work, the reliable manufacturing process of the high-performance strand was established, and the mass-production for the ITER Center Solenoid Model Coil was started.
