A nonlinear multimode frequency-domain analysis of the gyrotron is used to study the effect of excentricity of the electron beam on its performance. The guiding center of the electron beam which is usually at the center of the cavity is now shifted by a distance Δ c. Variations in the gyrotron output power, efficiency, and oscillation frequency pulling because of the electron beam excentricity have been calculated for a simple cavity gyrotron with oscillation frequency of 35 GHz. This paper also introduces the ability of varying the electron beam radius to limit the variations due to the electron beam excentricity.
