Influence of electron beam misalignment on characteristics of gyrotrons

A number of reasons such as technological errors in the process of gyrotron´s manufacture or inaccurate alignment of the magnetic field of the solenoid may lead to the formation of the misalignment. It means that we face a situation when the axis of the leading centers of the electron beam orbits do not coincide with the axis of the resonator. The effect that arises in this situation involves a violation of axial symmetry of the cavity-beam. With increasing of output frequency of the device this problem becomes more acute and almost inevitable.
