INVESTIGATION OF THE INTERACTION BETWEEN AN ELECTRON BEAM AND PLASMA

Results of an experimental investigation of the interaction between a modulated and unmodulated beam of high energy electrons and the high frequency discharge plasma are presented. It is shown that when the unmodulated beam moves through the plasma, oscillations arise in the beam which possess a frequency close to that of the plasma. The dependence of the oscillation amplitude on the fre quency and parameters of the plasma was determined. Coherent energy losses of electrons in a modulated and unmodulated beam passing through the plasma were inve stigated. (auth)
