| 摘 要： | 破裂诱发的Halo电流会流进内真空室结构，对偏滤器支撑结构有较大的破坏。通过安装在偏滤器支撑结构上的罗柯夫斯基线圈对EAST中Halo电流进行了研究。通过分析不同位置的Halo电流信号，发现这些Halo电流具有环向不对称性，环向不对称因子为2.5， 的最大值是0.65。这些结果对EAST真空室电磁载荷分析有着重要的意义。

| Abstract: | In tokamak experiment, the plasmas with elongated cross-section is inherently unstable against vertical displacement, which easily results in disruption when the disruption induced Halo currents flow in the vaccum vessel, large Halo current will produce large damage to the divertor support. The Halo current features were researched in EAST by the Rogowski coils installed in the divertor. By analyzing Halo current at various places, it is found that the Halo currents are toroidal asymmetric, with peaking factor typically 2.5 and the maximum value of 0.65. These results are effective in analysis of EAST vacuum vessel electromagnetic loads. |
