| 摘 要： | 利用Matlab语言将EFIT程序反演计算过程进行优化整合，简化了程序操作步骤，并增加了对计算结果的分析与存储功能。利用整合后的 EFIT 程序，计算分析了 J-TXET 装置放电过程中等离子体磁场位形和其它参数的演变，绘制了等离子体压强剖面图、等离子体电流密度和安全因子分布等磁面信息的重建结果。此外，还将反演结果与软X射线测算数据进行比对。结果表明，改善后的EFIT程序能够初步满足对实验放电的反演计算分析要求，为J-TXET装置的放电控制和运行提供重要的参考数据。

| Abstract: | The Matlab language is used to integrate the equilibrium fitting code (EFIT), which simplifies the code’s procedure and adds the analysis function to the results. In the calculation of equilibrium reconstruction, the improved EFIT code is used to get the pressure of plasmas, internal magnetic surface and plasma current density profile. In addition, the results of the calculation are compared with the experiment data from the X-ray. The results show that the improved EFIT code can meet the basic requirements to the equilibrium reconstruction calculation, and it can provide important reference data for the operation and control of the J-TEXT tokamak discharges. |
