摘要：

欧姆驱动条件下,托卡马克等离子体中的电流由欧姆驱动电流和等离子体内部的自恰电流构成。在简单的Spitzer电阻率模型下,欧姆驱动的环向电流密度剖面,主要由每一时刻的电子温度剖面和有效电荷数Z_eff的剖面决定。讨论并给出了确定了平衡位形的基本方程,在大环径比近似下,给出了存在锯齿振荡条件下的环向电流剖面和小的非圆变形的平衡解。

关键词: 欧姆驱动, 托卡马克平衡位形, 锯齿效应

Abstract:

For ohmically driven tokamak plasma , the total plasma current is composed of ohmic current and internal self-consistent component. For a simplified Spitzer resistivity model , the toroidal current profile is determined by the electron temperature profile and the effective charge number Z_eff profile at each time. The derivation of the fundamental equation to determine this equilibrium configuration is given. In the large aspect ratio approximation , analytic solution on equilibrium configuration with small non-circular deformations is obtained for sawtoothing plasma.

Key words: Ohmic drive , Tokamak equilibrium , Sawtooth oscillation
