【摘要】 通过将波迹方程与相对论情况下的完全Fokker Planck方程联合进行求解,研究了寻常波基频电子回旋波从托卡马克等离子体中平面弱场侧发射时的电流驱动。数值结果表明:随着等离子体电子密度、温度的提高,功率沉积和电流分布的位置将向等离子体的边缘方向偏移,并且产生的总的驱动电流随之减小;入射波极向发射角和环向发射角度的改变对功率沉积、电流分布及其大小产生明显的影响。更多还原

【Abstract】 Electron cyclotron current drive is investigated with the relativistic Fokker-Planck equation incorporated into a ray tracing code in the condition that the O-mode fundamental electron cyclotron (EC) waves are launched from the medium plane at the low field side in the paper. Numerical results show that, with increase of plasma temperature and density, both power deposition and current profile move towards the edge of plasma and the total driven current declines. The change in toroidal and poloidal injecting angles of EC waves can dramatically affect the power deposition, current profile and the total current.更多还原
