| 摘 要： | HL-2A装置MHD不稳定性实时预测破裂系统采用了一种简单有效的方法来预测MHD不稳定性导致的等离子体大破裂。利用Mirnov线圈探测MHD信号，根据信号的振幅或频率特点设定计算方法，来预测等离子体破裂先兆，然后用激光吹气注入杂质来缓解等离子体破裂。研究结果表明，该系统能够实时预测破裂先兆，按量注入杂质后，可达到破裂缓解目的。

| Abstract: | A effective method has been proposed to predict the major disruptions caused by MHD instabilities and a real-time disruption prediction system on the HL-2A tokamak has been developed successfully,in which the amplitude or frequency of the MHD signal detected by a Mirnov coil is checked to predict the major disruption and the injecting-impurity method is used to mitigate the major disruption by means of the laser blow-off system.The response time of this system is 1ms and,therefore,it satisfies the experimen... |
