轴对称托卡马克中的电子回旋电流驱动效率

Electron cyclotron current drive efficiency in an axisymmetric tokamak

Cesar Gutierrez-Tapia, Monica Beltran-Plata

摘要:

应用新经典输运理论计算了轴对称托卡马克装置低碰撞区的电子回旋电流驱动效率。托卡马克排序是用来获得一个系统的方程,描述的等离子体的动力学,其中包括由于高功率RF波的非线性有质动力(PM)的力量。PM力是在特定极向位置处的电子回旋共振表面周围产生的。在第一和第二谐波的情况下(对于不同的入射角的RF波)的ECCD效率进行了分析,并验证了从TCV和T-10托卡马克的实验参数值。所得结果与格林函数法所得结果一致。

英文摘要:

The neoclassical transport theory is applied to calculate electron cyclotron current drive (ECCD) efficiency in an axisymmetric tokamak in the low-collisionality regime. The tokamak ordering is used to obtain a system of equations that describe the dynamics of the plasma where the nonlinear ponderomotive (PM) force due to high-power RF waves is included. The PM force is produced around an electron cyclotron resonant surface at a specific poloidal location. The ECCD efficiency is analyzed in the cases of first and second harmonics (for different impinging angles of the RF waves) and it is validated using experimental parameter values from TCV and T-10 tokamaks. The results are in agreement with those obtained by means of Green's function techniques.
