A simulation of a disruption in the experimental advanced superconducting tokamak (EAST) is carried out with the CarMa0NL code and the results are successfully compared with the experimental data. The fundamental role of three-dimensional (3D) features of conducting structures surrounding the plasma is demonstrated and is fully accounted for in simulations. The results demonstrate that the currents measured by Rogowski coils placed around the supports of in-vessel plasma facing components (PFCs) are largely due to eddy currents induced by the plasma motion and current decay, with a relatively small contribution coming from the currents directly injected from the plasma into the structures (halo currents).
実験的先进超导托卡马克（EAST）中的破裂模拟使用CarMa0NL代码进行，并将结果与实验数据成功进行了比较。环绕等离子体 facing 组件（PFC）支撑结构的Rogowski线圈所测量的电流，主要来源于等离子体运动及电流衰减所感应的涡流，而直接由等离子体注入结构的电流（halo电流）贡献相对较小。研究证明了导电结构三维特性在破裂过程中的关键作用，并在模拟中得到了充分体现。
