Особенности взаимодействия встречных электронных потоков в трубе дрейфа

Мозговой Ю. Д., Хриткин С. А.

In the linear approximation is carried out numerical simulation and analysis of the features of the interaction of colliding electron beams in a drift tube with the reduction ratio of plasma oscillations and electronic interaction between threads. In the hydrodynamic approach in the weak signal wave technique developed theories related to space-charge waves colliding electron beams. Write an equation relating the plasma waves and electron beams obtained dispersion equation continuous four-two-beam interaction, which is valid over a wide bandwidth for different values of the parameters of decreasing Coulomb forces with distance, and the coefficients of the electronic interaction between threads. In the single-mode approximation in each of the interacting flows spread fast and slow space-charge wave (electronic or plasma wave beams). It was obtained solution of the dispersion equation in three modes and fourwave communications space-charge waves. The features of the modes of interaction such as BWO-amplifier, directional coupler with a periodic or aperiodic wave coupling in the case of interaction of colliding wide and narrow electron beams in the drift tube.
