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 experimental requirements.
