High harmonic rectangular gyrotron
Abstract
A high harmonic gyrotron using an axially grooved rectangular waveguide and a ribbon type electron beam is developed to avoid high magnetic field provided by superconducting magnets. Electromagnetic field configuration for the grooved waveguide are determined by matching the proper boundary conditions at the entrance of the side slots. The dispersion equation of cyclotron maser instability is derived by solving the relativistic Vlasov equation consistent with Maxwell's equations. The device dimensions are determined by maximizing the power gain by linear theory. The energy conversion efficiency is calculated through nonlinear particle simulations.
