MOTION OF INDIVIDUAL CHARGED PARTICLES IN A MAGNETIC FIELD WITH A HELICAL SYMMETRY,

Abstract

By means of the drift theory and a numerical integration of exact equations, an investigation was conducted of motion of individual charged particles in 'straight' helical magnetic field. The question is studied of obtaining high speeds of a 'useful' drift which is necessary for suppression of effects, causing a striation instability of plasma. It was shown that magnitude of drift is determined by the position of point of injection with respect to the separatrix and to parameters of the field. The optimum from the point of view obtainment of high speeds 'of useful' drift and confinement of particles in the working region is an injection near separatrix in the region of its maximum, with Larmor radii, comparable with the radius of separatrix. The region of angles of injection, with which is observed 'useful' drift, is found to be fairly narrow. A stable 'useful' drift is obtained during injection of particles outside the separatrix, where the field increases from center at any azimuth. (Author)
