Influence of electromagnetic effects on the two-stream instability in a relativistic electron beam

摘要

The influence of the electromagnetic effects on the two-stream instability in a relativistic electron beam propagating through a collisionless plasma channel is investigated, and a closed algebraic dispersion relation of the two-stream instability for the complex eigenfrequency omega is obtained. It is shown that electromagnetic effects have a strong stabilizing influence on the two-stream instability in a relativistic electron beam, drastically enhancing the critical beam current for instability.
