弗拉斯卡蒂托卡马克升级版中分析了电子回旋加速器 (EC) 共振加热 (ECRH) 放电平顶阶段高能失控电子的行为。据观察，等离子体加热引起的电场衰减会导致电子能量迅速下降，这常常导致失控粒子群的猝灭。研究了这种失控缓解方案的效率及其对等离子体条件的依赖性，特别强调了 EC 波注入期间所需的电场降。
The behaviour of high energy runaway electrons during the flat-top phase of electron cyclotron (EC) resonance heated (ECRH) discharges has been analysed in the Frascati Tokamak Upgrade. The decay of the electric field due to plasma heating has been observed to result in a rapid fall in the electron energy that frequently leads to quenching of the runaway population. The efficiency of this runaway mitigation scheme and its dependence on the plasma conditions has been investigated with particular emphasis on the required electric field drop during EC wave injection.
