Nonlinear Simulation of a Gyrotron in High Mode

XIAO Yan, YAN Yang, WU Jianqiang (School of Physical and Electronics, University of Electronic Science Technology of China, Chengdu 610054)  
The interaction between an electron beam and electromagnetic waves in the RF field inside a weakly irregular waveguide is analyzed to derive electron motion equations. Independently developed, numerical simulation software of on beam-wave interaction for a gyrotron in high mode is adopted to make self-consistent nonlinear simulations for a 220GHz gyrotron. The influences of velocity ratio, E-beam eccentricity and velocity spread on the beam-wave interaction efficiency in TE10、4 mode are analyzed.
