仿星器的主要优点是其稳态运行的能力。如果可以实现 β∼10% 的稳定等离子体约束，则可以将其用作反应堆。因此，这个极限压力值是仿星器研制的关键因素。本文对当前关于足够高压仿星器的磁流体动力学平衡和稳定性能的观点进行了调查。在这里，任何由外部电流产生的嵌套环形磁表面系统都被认为是仿星器。由螺旋或等效绕组产生的系统，包括扭转管和日光管，将被称为普通仿星器，与具有空间轴的系统相反。结果表明，可以实现充分的限制。
The main advantage of a stellarator is its capability of steady‐state operation. It can be exploited as a reactor if stable plasma confinement can be achieved with β∼10%. Therefore, this limiting pressure value is a key factor in stellarator development. This paper contains a survey of current ideas on the magnetohydrodynamic equilibrium and stability properties of stellarators with sufficiently high pressure. Here, any system of nested toroidal magnetic surfaces generated by external currents is considered a stellarator. Systems produced by helical or equivalent windings, including torsatrons and heliotrons, will be called ordinary stellarators, in contrast to those with spatial axes. It is shown that adequate confinement can be achieved.
