Confinement of Plasma Particles in a Corrugated Magnetic Field

Abstract

The particle orbits in a corrugated magnetic field having neutral points, at which the magnitude of the field vanishes, are studied. An axially symmetric case is treated in detail and the effect of the curvature is also considered. It is shown that the charged particles do not escape from the neutral points when they are situated several Larmor radii inside the line of force which passes through the neutral points.
The possibility of the confinement of a hot plasma in a general corrugated field including the case studied previously by Kadomtsev is discussed.
