摘要: 通过将相对论FokkerPlanck方程与波迹方程联合求解,对HL-2A装置中的电子回旋波电流驱动进行了数值模拟,研究了在HL-2A单零偏滤器条件下,中平面弱场侧发射的电子回旋波寻常波电流驱动。结果表明,HL-2A中的电子回旋波电流驱动效率较低并且受温度影响较为明显。

Abstract:

A numerical simulation of electron cyclotron current drive in HL-2A tokamak is performed with the relativistic FokkerPlanck equation incorporated into a ray tracing code. With the singlenull divertor configuration on the HL-2A tokamak,the current dirve for the ordinary electron cyclotron wave, injected from the low field side, are analyzed. Numerical results show that current drive efficiency is low and can be affected dramatically by the change of temperature in HL-2A.


Key words: HL-2A, electron cyclotron wave, current dirve
