Transport of a relativistic electron beam in a plasma
Abstract
The paper presents results of an experimental study of the transport of a relativistic electron beam with a current of up to 30 amps, an energy of about 1 MeV, a pulse duration of about 60 nanoseconds and a beam diameter of 2.5 cm in a longitudinal magnetic field. It propagated through a plasma of a density up to 10 to the 11/cu cm, generated by a low-energy electron beam. Axially asymmetrical oscillations were observed in the beam-plasma system in the frequency range 40-120 MHz. The frequency of the oscillations grew with the growth of the density of the decaying plasma. The most intense oscillations which led to the strong modulation of the relativistic beam, were observed during beam-neutralization. At certain high plasma densities (10 to the 10-10 to 11/cu cm) the oscillations disappeared.
