【 摘 要 】

We study the stability and nonlinear evolution of differential streaming between core and beam protons based on the analysis of a nonlinear kinetic dispersion relation and using hybrid simulations describing the self-consistent decay of Alfve´n-cyclotron waves. The effects of ion trapping by ion acoustic waves and pitch-angle scattering induced by decay of the Alfve´en-cyclotron waves are discussed.
