“…Substituting these values into the equation of continuity (4), we find the perturbation of the charge density and current density of the electron beam. Then, taking into account (5), we obtain from Eq. ( 3) the expression for E z , which we use in the boundary condition on the inner surface of the waveguide (1)…”

The excitation of an electromagnetic TM mode by a relativistic electron beam in a waveguide with a sinusoidalcorrugated azimuth conducting wall in a constant uniform external guiding magnetic field is theoretically studied. We consider a thin annular electron beam moving along the waveguide axis and rotating at an equilibrium radius around its axis. In the approximation of a small corrugation depth, the analytical dependences of the growth rate of instability and resonant frequencies on the parameters of the beam and waveguide are determined.

The relativistic magnetrons operating at millimeter wavelengths demonstrate problems with microwave power extraction, both in the radial and in axial direction. The preferred axial extraction concept can be implemented ei-ther as ‘diffractional output’ or via introduction of additional resonant elements into the output waveguide. In this paper several solutions for axial-directed extraction are discussed, including circular ring ‘antennas’ at the end of the anode-cathode space, and resonance-length rods at the faces of the anode-block cavities. These have allowed increasing the power extraction efficiency by a factor of 101 to 102.
