Title: PLASMA DIFFUSION IN SYSTEMS WITH PARTICLE LOSSES

Abstract

In some experimental fusion devices, plasma is confined by a magnetic field and steadily lost out of the ends of a magnetic bottle. When the scattering rate of particles is high, field diffusion and particle loss can be considered from a macroscopic point of view. The formation of a steady-state sheath into which particles diffuse only to be lost along the lines of force is noted. The theory is developed to the extent that the original approximations are evident, though the theory remains essentially phenomenological. It is shown that a steady-state plasma sheath is formed whose thickness depends on the plasma resistivity, sound speed, and length. The sheath moves into the plasma with a speed which depends on the same parameters. (auth)
