Abstract We have carried out particle simulations in order to study the effects of beam plasma interaction and the propagation of an electron beam in a plasma with a magnetic field. It is found that the beam plasma instability results in the formation of a high energy tail in the electron velocity distribution which enhances the mean free path of the beam electrons. Moreover, the simulations show that when the beam density is much smaller than the ambient plasma density, currents much larger than the thermal return current can be injected into a plasma. Results from the two-dimensional simulation indicate that the beam particles suffer large radial diffusion due to a c E × B /B2 drift.
