Cyclotron Instabilities in a Finite Pressure Plasma. II

Abstract

Cyclotron instabilities in mirror confined plasmas are investigated, without use of the electrostatic approximation. A “j=1” anisotropy-loss-cone distribution is taken for the ion velocity distribution function and the electron is assumed cold. We found the analogous non-electrostatic instability which has been obtained in the part I of this paper. It is shown that this mode can be stabilized if cyclotron damping due to a small but finite k_|| is taken into account.
