摘要:

利用模拟得到的平衡数据进行了等离子体平衡重建,将结果与准确的平衡结果进行细致对比,验证实时等离子体平衡重建程序的准确性;同时在模拟产生平衡数据的过程中引入随机误差,验证反演程序的强壮性。此外,实时等离子体平衡重建程序还使用EAST装置的实验数据进行反演,将反演结果与EAST的RTEFIT反演结果对比,验证了单一时间平衡重建结果和连续时间反演结果的正确性。结果表明,选择合适的电流分布模型和磁诊断数据,通过等离子体平衡重建算法可以正确识别等离子体位形。

Abstract:

The simulation results of the plasma reconstruction were obtained and compared with the accurate balance results. With the introduction of random errors in the simulation process, robustness of the inversion procedure had been verified. The reconstruction results using the experimental data from EAST device had been compared with the inversion results from EAST’s RTEFIT to verify the correctness of the results that a single time and the continuous-time inversion. The results show that, choosing the current distribution model and magnetic diagnostic data through the equilibrium reconstruction algorithm can correctly identify the plasma shape.
