Abstract

A high-current superconductor is indispensable to large coils for the fusion machine. The high-current superconductor can be developed by using advanced techniques. Japan Atomic Energy Research Institute (JAERI) has developed the Demo Poloidal Coils (DPC) which has a nominal current of 30-kA and an inner diameter of 1m. During the charging test of the coils, an instability was observed in the superconductor. This is the most serious difficulty in which we met until now. Many verification tests were carried out step by step to solve this technical problem, for about three years. We have finally solved the problem and developed improved conductors. The improved conductor was tested and good results were obtained. Through this development, we could obtain the confidence that an other new technical problem can be solved by using the same method.
