提出了一种小型仿星器线圈的设计方法。与从最优连续表面电流分布中选择有限数量线圈的方法相反，COILOPT代码在与等离子体边界分离良好的环面绕组表面上以模块化线圈的显式表示解决了最优参数，以及绕组表面的系数。问题是在近似规定的磁结构和满足某些关键工程要求之间取得平衡。给出了准轴对称和准极向紧凑仿星器的设计结果。
A method is presented for designing coils for compact stellarators. In contrast to methods that select a finite number of coils from an optimal continuous surface current distribution, the COILOPT code solves for the optimal parameters in an explicit representation of modular coils on a toroidal winding surface that is well separated from the plasma boundary, together with the coefficients of the winding surface. The problem is posed as a balance between approximating a prescribed magnetic configuration and satisfying certain critical engineering requirements. Results are presented for quasi-axisymmetric and quasi-poloidal compact stellarator designs.
