Abstract

Potential enhancement due to RF-induced parallel velocity space diffusion in a tandem mirror is studied by using a one-dimensional model based on the linearized Fokker-Plank equation with a quasi-linear RF diffusion term. A modified Boltzmann relation between the plasma density and the confining potential is obtained as a function of the RF diffusion coefficient under the assumption of small deviation from the Maxwellian for distribution function. The relation shows that the confining potential increases with the increase of the RF diffusion coefficient. The confining potential is saturated for the flat distribution function in the limit of strong RF diffusion.
