Abstract

Influence of the magnetic field tapering on gyrotron operation is studied by generalizing the η(μ,F) plot, which is most useful for the optimization of a gyrotron design. It is found that in general a positive magnetic field taper increases efficiency, but at the same time increases the danger of self-excitation of parasitic modes, while a negative magnetic field taper decreases efficiency and reduces the probability of self-excitation of parasitic modes.
