中文摘要
    等离子体破裂会对托卡马克装置的安全运行造成严重威胁。等离子体破裂期间电流猝灭速率与电磁负载的大小及逃逸电流平台的形成都密切相关。本文对HL-2A装置等离子体破裂进行了统计分析,统计选用等离子电流的两个衰减区间90-10%和80-20%。分析结果表明:HL-2A装置等离子体破裂有四种不同的电流猝灭波形,两个衰减区间最小电流猝灭时间的参数区分别为2.6 ms和2.2 ms,并且不同衰减区间下平均电流猝灭时间统计分布明显不同。
英文摘要
    Plasma disruption constitutes a serious threat to the safety of tokamak devices. The quench rate of current during plasma is closely related to the magnitude of electromagnetic forces and the formation of runaways beam. In this paper, the data of current quench have been statistically analyzed by using 90-10% of the pre-disruption and compared with the experimental results in the range of 80-20%. The experimental results show that there are four different current quench waveforms on HL-2A. The minimum current quench time is 2.2 ms and 2.6 ms, respectively. The statistical distribution of mean current quench time are obviously different in the two different intervals.
