There is considerable interest in the use of beam--plasma discharges for separating isotopes and elements. This paper reports a study of a low-temperature Ar--He plasma formed by injecting a 10-kW electron beam. The plasma is immersed in a longitudinal mirror magnetic field and a radial electric field. A single Langmuir probe and a mass-spectrometric technique are used to find the radial profiles of the density, the plasma potential, the electron temperature, and the components of the working mixture. There is a pronounced decrease in the plasma density in the beam region, and a corresponding decrease in the instability growth rate. The radial electric field increases the size of the region of reduced plasma density in the beam region and even suppresses the beam--plasma interaction.
