Abstract: Title:Theory of Energetic Particle Modes Excited by Energetic Ions in Tokamaks
Abstract:In this report, specific expressions for real frequencies, growth rates and threshold conditions are derived for pure EPM under two distribution functions of energetic ions, that is, anisotropic slowing-down beam ion distribution function and maxwellian distribution. Mode growth rate and frequency is found as a function of plasma β, circulating-particle energy and distribution.
