介绍了紧凑型星状星在理论理解和设计方面的最新进展。混合器件由一类低纵横比的A<；4星化器组成，它从流经有限贝塔的自举电流中获得好处，从而不同于正则星化器。在没有导电壁的情况下，它们具有外部扭结稳定性(在中等β下)，通过外部控制转变和磁性剪切，可能对破坏具有免疫力，并且它们实现了与托卡马克相似的体积平均气球贝塔极限(4%-6%)。此外，自举电流可以减少磁岛(自愈效应)的影响，并通过减少所需的外部变换而导致更简单的星体线圈。已经开发了强大的物理和线圈优化代码，并将其整合在一起，以设计旨在探索紧凑型星体的实验。讨论了设计国家紧凑型星光仪的物理基础。
Recent progress in the theoretical understanding and design of compact stellarators is described. Hybrid devices, which depart from canonical stellarators by deriving benefits from the bootstrap current which flows at finite beta, comprise a class of low aspect ratio A<4 stellarators. They possess external kink stability (at moderate beta) in the absence of a conducting wall, possible immunity to disruptions through external control of the transform and magnetic shear, and they achieve volume-averaged ballooning beta limits (4%–6%) similar to those in tokamaks. In addition, bootstrap currents can reduce the effects of magnetic islands (self-healing effect) and lead to simpler stellarator coils by reducing the required external transform. Powerful physics and coil optimization codes have been developed and integrated to design experiments aimed at exploring compact stellarators. The physics basis for designing the national compact stellarator will be discussed.
