摘    要:将理想全二维磁流体(MHD)稳定性数值代码GATO成功移植到HL-2A高性能计算系统,并用其模拟研究了HL-2A装置一次典型弹丸注入实验的等离子体的理想MHD稳定性。利用HL-2A装置第4050次放电的实验数据,应用EFIT代码重建了几个时间片的平衡位形,然后应用GATO代码对每个平衡位形的MHD稳定性进行了计算。通过对结果进行分析比较得出初步结论,由于弹丸注入而造成的反剪切位形的致稳作用,可以提高等离子体的约束性能。

关 键 词:GATO代码  HL-2A高性能计算系统  理想MHD不稳定性  EFIT代码

Abstract:The ideal two-dimensional MHD stabilities code, GATO, has been successfully immigrated to the high-performance computing system of HL-2A and used to the simulation study of the ideal MHD stabilities of the plasmas produced by one of the pellets injection experiments on HL-2A tokamak. The EFIT code was used to reconstruct the equilibrium configures firstly and the GATO was used to compute their MHD stabilities secondly whose source data were obtained by the No.4050 discharge of the experiments on HL-2A, and finally by analyzing these results the preliminary conclusion was devied that the confinement performance of the plasma was improved because of the stabilization effect of the anti-sheared configures created by the pellets injection.
Keywords:GATO code  HL-2A high performance computing system  Ideal MHD instabilities  EFIT code
