Abstract

A complex cavity with gradual transition is employed in the 94 GHz gyrotron. A self-consistent field nonlinear theory has been used and numerical simulations for electron beam interaction with RF modes are given. A pulse output power of 235.2 kW is obtained by simulation at a beam voltage of 60 kV with beam current of 10 A, a velocity ratio of 1.45, and magnetic field 17kG, corresponding to an efficiency of 39.2%.
