| 摘 要： | 通过将相对论Fokker-Planck方程与波迹方程联合求解,对ITER(国际热核实验反应堆)参数下的电子回旋波电流驱动进行了数值模拟。结果表明,当波的环向发射角度不太大时,波功率沉积将发生在ITER的强场侧。当环向发射角度为21°时,电子回旋波的能量在等离子体中心区域被吸收并驱动起等离子体中心区域的电流。当发射角度变大时,电子回旋波将在弱场侧沉积功率。当发射角度为20°～30°时,能够驱动归一化的径向位置(r/a)小于0.35区域内的等离子体电流,并有较高的电流驱动效率。

| Abstract: | A numerical simulation of electron cyclotron current drive under ITER (International Thermonuclear Experimental Reactor) parameters was performed with the relativistic Fokker-Planck equation incorporated into a ray tracing code. While the toroidal incident angles are not very large, the wave power deposits in the high-filed-side of ITER. While the toroidal incident angle is 21°, the wave power deposits in the central plasma and the plasma current in the central plasma is driven. While the toroidal incident angles turn to large, the wave power deposits in the low-filed-side of ITER. Electron cyclotron waves are able to drive the plasma current in the area r/a ＜0.35 and have a higher current drive efficiency while the incident angles are in the range of 20° to 30°. |
