THE EFFECT OF FINITE ION AND ELECTRON TEMPERATURES ON THE ION CYCLOTRON RESONANCE INSTABILITY

摘要

The effect of finite ion and electron temperatures on the ion cyclotron resonance instability is investigated for the Burt/Harris model of a confined plasma cylinder. This is a cylinder of plasma in which the ions move in concentric Larraor orbits with their centres on the axis of the cylinder.nBy discussing changes in particle orbits produced by a self-consistent potential perturbation, a dispersion relation is derived, which has been studied analytically and numerically. Results are presented graphically for cold electron, cold ions, and equal ion/ electron temperatures, showing stability criteria and growth rates.
