Wendelstein 7-X （W7-X）仿星器的磁构型对ι/2π = 1共振磁场的扰动敏感。这种扰动可能是由实际线圈系统的电流灯丝位置与设计的偏差引起的，这是由于在线圈制造和磁铁系统组装期间可以实现的精度。通过在给定公差范围内引入随机分布的线圈形状和位置误差，研究了磁场对不同类型误差的敏感性。对这些误差分布进行了统计分析。在完成每个组装步骤之前，该程序将用于评估W7-X的磁性配置。
Abstract The magnetic configurations of the Wendelstein 7-X (W7-X) stellarator are sensitive to perturbations of the magnetic field resonant with ι/2π = 1. Such perturbations can be caused by deviations of the current filament positions of the real coil system from the design due to the accuracy achievable during the manufacture of the coils and assembly of the magnet system. The sensitivity of the magnetic field to the different types of error has been investigated by introducing randomly distributed errors to the coil shapes and positions within the given tolerances. A statistical analysis of these error distributions was performed. This procedure will be used to assess the magnetic configuration of W7-X before the completion of each assembly step.
