FOR NONLINEAR NONSTATIONARY THEORY OF TWO-STREAM TRAVELING-WAVE TUBE AMPLIFIER AND TWO-STREAM AMPLIFIER: GENERAL EQUATIONS AND SOME RESULTS OF CALCULATION

In the work shows a way of developing the theory of nonlinear non-stationary two-beam traveling wave tube with a codirected beams, based on the nonlinear theory of traveling wave tube with a single electron beam.
