摘要
本文利用磁探针阵测量清洗放电前ＭＵＴ托卡马克中角向磁场的分布，从而计算得到了等离子体的电流分布。结果表明，在清洗放电初期，由于存在大量杂质，等离子体的横向扩散非常大，因而，真空室的绝缘段几乎不起绝缘作用。此时所测到的环向电流中绝大部分是流经厚壁真空室的电流。
The poloidal magnetic field distribution of MUT tokamak was measured by a magnetic probe array during the cleaning discharge.The result shows that at the beginning of cleaning discharge,the isolation section of the vacuum chamber no longer plays the isolating role because of a very large transverse plasma diffusion due to huge impurity.Most of the measured toroidal current is the current passing through the thick vacuum chamber.
