It is shown that thereexist the modes with generation of chaotic signals and synchronization modes with high signal-to-noise ratio.The effect of parameters of the electron beam and external feedback on the generation frequency of the systemand phase relations between the signals generated in each module is analyzed6 pages, 5 figures, 1 tablePlasma Physicstext
