According to the Maxwell equation and Lorentz force, the equations of motion describing the mode of operation under electron beam and the equation of motion of the electron beam under the mode of operation are given by using the electron beam as the excitation source (ie, the microwave cavity Self-consistent equations between the electron beam and the microwave field) .According to the self-consistent equations, the interaction between the electron beam and the single-gap microwave cavity at any time is further studied.By analyzing the effect of the electron beam and microwave in the microwave cavity Linear and nonlinear processes, the effects of the modulation depth of the electron beam and the gap of the microwave cavity on the microwave output power are given.Finally, the comprehensive physical parameters that affect the microwave output power are given theoretically.
