摘要：
The unique features associated with the appearance of static regular components of the noise spectrum in devices with prolonged interaction, caused by plasma-ion oscillation, are determined in this paper and the possibilities for reducing the influence of these oscillations on the amplitude of the output signal are determined. The investigations were carried out in the three-centimeter band for the interaction of an 0. 8-mm diameter cylindrical electron beam in a longitudinal magnetic field of up to 4 kG with the minus first spatial harmonic of the field of a comb in the self-excitation regime of an 0-type BWT and for pre-modulation of the electron beam by a microwave signal. An analysis of the microwave signal level, the amplitude and frequency of its side components was made using an IV-66 spectrum analyzer. The amplitude and frequency of the plasma oscillation were measured with an SMV-6. 5 selective microvoltmeter.
