| 摘 要： | 在考虑了电子的反弹平均效应及高能电子的相对论效应下，通过数值求解电子的Fokker-Planck方程，研究了托卡马克等离子体中快波与电子回旋波电流驱动问题。采用九点差分法对方程进行离散，应用近似LU因子分解法对方程进行了数值求解。计算结果表明快波与电子回旋波联合电流驱动具有很强的协同效应，在两波联合电流驱动下，驱动电流大于单波电流驱动之和。

| Abstract: | The problem of electron cyclotron wave and fast wave current drive is studied by solving the Fokker-Planck equation in a numerical method for tokamak plasma. Effects of both bounce-averaging and relativity for electrons are considered in the process of solving. The Fokker-Planck equation is discretized by nine points difference technique, and solved by incomplete LU factorization. The results are shown that high synergetic effects are existed by combined current drive of electron cyclotron wave and fast wave, and the size of current density driven by the two waves is higher than total of the two single one. |
