  plasma equilibrium
Plasma equilibrium in axisymmetric open divertor configurations
      
The issue of how the plasma equilibrium changes as the parameter β≡8πp/B2 increases is considered for a fairly representative class of pressure profiles p(ψ) (where ψ is the flux coordinate).
      
The phenomenon of the internal transport barrier in a tokamak plasma is interpreted as a bifurcation of the plasma equilibrium.
      
An expression describing the change in the plasma pressure due to the buildup of the barrier is derived as a functional dependent on the parameters of the original plasma equilibrium and the plasma rotation velocity within the barrier.
      
This shift is calculated analytically, and this effect is exemplified by simple plasma equilibrium states.

In this article, the effects of the small magnetic field perturbation on the equilibrium of plasma are discussed (the problem of the static stability of plasma). It is pointed out that a large variation in the equilibrium configuration may take place only when the small magnetic perturbations couple with the plasma modes which are almost neutally stable. Accordingly, the effects of the main classes of the stray field in Tokamak devices are analysed.

本文讨论了外磁场微小的变动对等离子体平衡位形的影响,即等离子体的静态稳定性问题。指出,只有当附加磁场与等离子体接近不稳定边界的模相耦合时,才可能引起平衡位形很大的变化。由此,我们分析了杂散场对环电流器(托克马克)的影响。

In the free-boundary case, the extremum of the potential functional is found from the variational principle. Thereby the equation and boundary conditions required for plasma equilibrium are derived. The Euler equation of the relevant functional is the magnetic surface function equation with the condition of free boundary. A variational functional suitable for numerical computation is given.

In the free-boundary case, the extremum of the potential functional is found from the variational principle. Thereby the equation and boundary conditions required for plasma equilibrium are derived. The Euler equation of the relevant functional is the magnetic surface function equation with the condition of free boundary. A variational functional suitable for numerical computation is given. This functional corresponds to a boundary value problem with an equal-value surface boundary condition. For the case of a conducting wall of simple geometry (i.e., a rectangular wall), numerical computation has been carried out by using the Ritz method.

在自由界面情况下用求位能汛函极值的变分原理推出了等离子体平衡所需满足的平衡方程和边界条件;其泛函的Euler方程即为具有自由界面条件的磁面函数方程。也给出了便于计算的变分泛函,它相当于等值面边界问题。对于导体壁为简单几何形状的情况,用Rit法进行了数值计算。

The iteration method for solving the free-boundary magnetic surface equation with conducting shells has been generalized to the case of infinite region with external currents and without conducting shells. In order to do this a coordinate transformation of the form x' = x/1+x is carried out which enables to get a sufficient accuracy in

本文将文献[1]中求解有导体壁的自由界面磁面方程的迭代计算方法推广到无导体壁的无穷远区域中。为此,引进坐标变换x′=x/(1+x),这样既可以在等离子体所在区域保持足够的精度,又可以在真空区大大加大步长。然后,对等离子体电流存在的径向范围作出限制后,用文献[1]中同样的迭代序列,可以找到经过外侧径向限制器的等离子体平衡解。文中以一维模型为例,用这种方法得到数值解后,和严格的解析解作了比较,讨论了解的特点。这种方法,可以毫无困难地推广到二维的情况。
