The Study of Electron Cyclotron Waves Controlling Current Distribution in Tokamak

利用电子回旋波电流驱动定域性好的特点,在数值上研究了电子回旋波对托卡马克中电流分布的控制.结果表明:电子回旋波频率、功率和波发射角度对电流分布起重要作用,优化计算得到了一组波参数.在此波参数下可以有效地驱动等离子体中心电流,并使之满足等离子体平衡电流的分布形式.

Using the good locality of electron cyclotron current drive, the control of current distribution has been studied numerically in Tokamak by electron cyclotron wave, The resuits show that electron cyclotron wave frequency, power, and wave launch angle plays an important role on the current distribution. A set of wave parameters have been gained by optimized calculation, under which, the centre current of plasma can be effectively driven, and the distribution of plasma equilibrium current can be met.
