EAST极向场线圈及磁测量系统的修正

摘要

采用网格法计算空间磁场,应用最小二乘法优化极向场线圈、单匝环、磁探针位置参数及标定系数获得了更准确的位置坐标,明显地改善了磁场和磁通的计算误差,也为等离子体平衡反演算法提供更准确的格林函数.%An efficient method is given to correct the position and scales of poloidal field coil, flux loop,magnetic probe by using meshes to calculate magnetic field and least square approximation. The result reduces the different between calculated data and experiment signal. And then it provides a more accurate green function for equilibrium fitting algorithm.
