中空導体を用いた超電導電磁石

抄録

The superconducting magnet with hollow conductor has various merits, when it is compared with the conventional superconducting magnet, and it will be applicated for big bubble chamber, big spark chamber, etc. in near future. In this article, its merits, refrigeration systems, optimum operation, examples of superconducting hollow conductor, examples of actual magnets and future projects for big magnet in the world are presented.
