| Abstract: | We present the results of laboratory experiments in which the mechanisms of interaction of electron beams with whistler waves
in a magnetoplasma are studied. Different mechanisms of whistler generation during the injection of a modulated electron beam
in the plasma are studied, and the mechanism of conversion of the beam kinetic energy to radiation is demonstrated. The processes
of whistler wave generation by the modulated beam at the ˇ Cerenkov and Doppler resonances are analyzed in detail. The excitation
of whistler waves by means of a nonresonant mechanism of the transition radiation is studied. |
