Comparison of characteristics of current quenches using different intervals during disruptions
The value of electromagnetic load is closely related to the current quench characteristics in the toka-mak during plasma disruption.The characteristics include the current quench waveform and current quench rate,which will determine the life of the Tokamak device to a certain extent.The spontaneous disruption data of the HL-2A are statistically analyzed by using three different intervals of 100％-40％,90％-10％and 80％-20％,and the statistical results are compared and analyzed.The statistical results show that:under the same definition,not only the average current quenching time and current quenching rate distribution have the least difference between 100％-40％and 80％-20％,but also the average current quenching time and current quenching rate statistical distribution almost are the same.In addition to the 80％-20％range,the 100％-40％range can also be used as a suitable range to provide an approximation of the maximum linear average plas-ma current quenching rate.
