准螺旋对称仿星器是一种非轴对称环形结构,其中磁场强度仅取决于恒定压力表面内的一个角坐标,而不是两个。 这些结构的约束特性与轴对称托卡马克相似。 尽管具有精确准螺旋对称性的仿星器已被证明不存在,但仍可以找到良好的近似值。
Quasihelically symmetric stellarators are nonaxisymmetric, toroidal configurations in which the strength of the magnetic field depends on only one angular coordinate, instead of two, within the constant pressure surfaces. The confinement properties of these configurations are similar to those of axisymmetric tokamaks. Although stellarators with exact quasihelical symmetry are proven not to exist, good approximations can be found.
