| 本文从漂移动力论准线性Ｆｏｋｋｅｒ一Ｐｌａｎｃｋ方程出发，推导出在感应电场存在下，射频波驱动等离子体电流由新经典电流ｊＮＣ、射频驱动电流ｊＲＦ、欧姆电流ｊｏｈ和附加电流ｊｌ组成，并给出了在高相速度极限下的解析式．在密度、温度分布给定下，若与波迹方程和波功率变化方程相结合，可以求出ｊｌｌＢ在极向通量表面上的平均值（ｊｌｌＢ），从而可以求解描述等离子体平衡的Ｇｒａｄ－Ｓｈａｆｒａｎｏｖ方程，获得自洽的通量以及等离子体的平衡参量． |
| 英文摘要: |
| This paper, using the drift Kinetic Quasi-linear Fokker-Planck equation in the presence of both the induced electric field and the RF wave,derived the plasma electric current which consist of a neoclassical electric current jnc, a RF wave electric current jRF, an Ohmic electric current Joh and an additional electrical current jl, and gave the analytical expressions of these currents within the high-phase-speed limit. Given density and temperature profile, combining the Fokker-Plank equation with the ray equation and the wave power evolution equation, the poloidal flux surface average (jllB) can be calculated. Uponthis basis, the Grad-Shafranov equation for plasma equilibrium can be solved and the self consistent flux and some of the equilibrium parameters can be obtained. This theory can be applied to lower hybrid slow and fast waves to drive a steady current, a current rampingup or Oh coil recharging while a constant plasma current is maintained. The shape of the plasma boundary may be arbitrary, either circular or noncircular. |
