最近设计的优化仿星器实验受到非常严格的构造公差的影响，但是在线圈的制造和线圈系统的组装期间，线圈系统的一定程度的偏差是不可避免的。在本文中，我们提出了一种新的方法，将降低灵敏度的线圈系统到优化序列的建设公差。该方法在温德尔斯坦7-X现有线圈优化方案的框架内进行了测试。并将计算结果与原优化结果进行了比较。结果是具有较不严格的公差的更优化的线圈系统，使得小的偏差导致对熔合性能重要的性质的降低的劣化。
Recently designed optimized stellarator experiments have suffered from very tight construction tolerances, but some level of deviation of the coil system is unavoidable during fabrication of the coils and assembly of the coil system. In this paper, we present a new approach that incorporates reduced sensitivity to construction tolerances of the coil system into the optimization sequence. The approach was tested within the framework of the existing coil optimization scheme for Wendelstein 7-X. The results are compared with those of a coil set obtained by the original optimization. The result is a more optimal coil system with less stringent tolerances, such that small deviations cause reduced deterioration of the properties important for fusion performance.
