Summary
An approxintate method was developed for analyzing the stability of a stationary magnetohydrodynamic system. The method describes the stability problem with a self-adjoint operator, analogous to quantum mechanical perturbation methods. In this way, the stability of systems in the vicinity of an isothermal plasma cylinder with surface flow can be studied. To illustrate the method, a system for which an exact solution of the stability problem exists is considered, and the solution is found to agree with observed approximations. The effect of a small temperature gradient in the plasma cylinder on the time constant in the first approximation is discussed. A general investigation of a system coming out of a plasma cylinder by means of a deformation of the boundary surface shows that the variation of the deformation amplitude is of second order and that the growth time of a deformed THETA pinch can be estimated. The variation in a torus is likewise of second order, except that the radius proportion is used instead of the deforniation amplitude. For a THETA pinch configuration with a small axial flow, calculations were made in the first approximation. A stability criterion is presented. The effects of cylinder length and Larmor radii of particles are discussed.(D.L.C.)
