Abstract
We consider the design of a gyrotron with an operating frequency of 24 GHz and an accelerating voltage of about 5 kV and describe a nonadiabatic electron gun forming an electron beam with a pitch factor of 1.8 and a velocity spread of about 10%. Longitudinal distribution of high-frequency field in a cavity with a step is optimized by choosing the step height and length. The design value of the gyrotron output efficiency is 35% at the second gyrofrequency harmonic.
