实验轴对称平衡的重建是托克马克数据分析的重要组成部分。在EFIT程序中，采用傅里叶展开法重建了船舶流场。基准测试和测试计算进行评估和验证该算法。圆形和非圆形等离子体放电的两种情况下。采用傅立叶展开法拟合涡流场是一种鲁棒的方法，可以将真实的实时EFIT引入到即将到来的等离子体控制系统中。
Reconstruction of experimental axisymmetric equilibria is an important part of tokamak data analysis. Fourier expansion is applied to reconstruct the vessel current distribution in EFIT code. Benchmarking and testing calculations are performed to evaluate and validate this algorithm. Two cases for circular and non-circular plasma discharges are presented. Fourier expansion used to fit the eddy current is a robust method and the real time EFIT can be introduced to the plasma control system in the coming campaign.
