Abstract :
From the electron motion equations and Maxwell equations, the coaxial gyrotron beam-wave coupling equations are derived and the coaxial gyrotron self-consistent theory of large-signal model is established. Using codes MATLAB, A set of codes is developed and the 170GHz, 1.7MW coaxial gyrotron beam-wave interaction is simulated. Based on self-consistent theory, the field profile, phase and efficiency are calculated. The influence of magnetic field on the beam-wave interaction efficiency are also studied and the results show that the work status of coaxial gyrotron is very sensitive to the magnetic field. The methods and conclusions provide a valuable reference for theoretical studies of other coaxial gyro devices.
