摘　　要：球形环是一种先进的磁约束核聚变研究装置 ,它保留了传统托卡马克装置的许多特点 ,比如说封闭磁面系统 ,中等旋转变换磁力线和好的等离子体约束性能等 ,同时又有低环径比 ,低纵向磁场 ,从而具有结构紧凑 ,造价相对低廉等优点 ,是有潜力的磁约束核聚变途径之一。概述了球形环的装置、实验。Spherical torus is an advanced magnetic confinement device for nuclear fusion research,which retains many features of tokamak configuration,such as closed magnetic surfaces and field lines of medium rotational transform,and good plasma confinement.In addition it has low aspect ratio and lower toroidal magnetic field,and it is compact,economical with respect to traditional tokamak. Therefore it has the potential for a nuclear fusion reactor. Present paper the engineering,experiment, and theory status as well as challenges in spherical torus research are comprehensively presented in this paper.
