Abstract

Relativistic electron beams propagating in plasma broaden as electric and magnetic fields scatter them. We calculate the beam spreading expected from errors in the ambient magnetic field, and from both electrostatic and magnetic waves generated by the beam itself. All these effects can be important in contemplated experimental regimes. Beam expansion can serve to set limits on the strength, size and phase velocity of caviton waves. Beam-driven magnetic waves can scatter beams effectively even if applied field errors are small. This can affect schemes for transport of beams in inertial fusion, and plasma heating schemes.
