一个简单的托卡马克破坏模型，考虑到失控电流取代等离子体电流，用于评估在快速破坏事件的电流熄灭阶段失控种群的产生和能量。讨论了等离子体中断时纹波共振和磁波动对失控电流抑制的潜在效率，以及它们对失控产生机制的依赖关系。对欧洲联合环面（JET）[核]进行了预测。核聚变25,1011(1985)]和计划中的国际热核实验反应堆（ITER） [ITER EDA协议和议定书2，国际原子能机构，维也纳，1994]。结果表明，当失控产生以Dreicer产生过程为主时，纹波共振导致失控束能量降低；但是，如果包括二次发生机制，则影响可以忽略不计。异常径向失控损失的影响
A simple model for a tokamak disruption, taking into account the replacement of the plasma current by the runaway current, is used to evaluate the generation and energy of the runaway population during the current quench phase of a fast disruptive event. The potential efficiency of the ripple resonance and the magnetic fluctuations for runaway current mitigation during plasma disruptions, as well as their dependence on the runaway generation mechanism, are discussed. Predictions are made for the Joint European Torus (JET) [Nucl. Fusion 25, 1011 (1985)] and the projected International Thermonuclear Experimental Reactor (ITER) [ITER EDA Agreement and Protocol 2, International Atomic Energy Agency, Vienna, 1994]. It is shown that the ripple resonance leads to a reduction in the runaway beam energy if the runaway production is dominated by the Dreicer generation process; however, the effect will be negligible if the secondary generation mechanism is included. The effect of anomalous radial runaway losses indu...
