摘要
通过对聚变堆级条件下的电子回旋波电流驱动(ECCD)进行模拟,研究了俘获电子效应对电流驱动及功率沉积的影响。结果表明:俘获电子会吸收更多的波功率,使波功率的沉积更加集中,并且使电流驱动效率明显降低。
With the numerical simulation of electron cyclotron current drive （ECCD） in reactor scale Tokamak, the influence of trapping electron effect on current drive and power deposition are studied. Numerical results show that,wave power will be absorbed further by the trapping electrons, power deposition profiles will become narrow, the current drive efficiency will by cut down clearly.
