Abstract

Cornwall et al. (1970) suggested that if the ring current protons penetrated the plasmapause, intense resonant electromagnetic ion cyclotron turbulence would lead to their rapid precipitation loss. IN this paper we present a computer simulation study of the electromagnetic ion-cyclotron instability in a homogeneous plasma consisting of protons and electrons embedded in a static magnetic field, B0x. The plasma parameters used are and Effects such as sources and losses or space non-uniformities are not considered here. The predictions of the linear theory for the fast build-up of unstable left-hand (proton-like) electromagnetic ion-cyclotron waves are fully confirmed.
