Abstract

The analytic theory for formation of intense helical electron beams in gyroresonance derives in a longitudinally inhomogeneous magnetic field is advanced. Criteria for the required degree of non-adiabaticity of the magnetic field sufficient to produce high oscillatory energy of electrons in the resonator cavity are formulated. Estimates for basic parameters of the beam (oscillatory velocities, position of the guiding center, velocity spread) are given for the step-wise and bell-shaped approximations of the magnetic field. The factors affecting the velocity spread are considered.
