Orotron with a Two-Row Periodic Structure at a Wavelength of 1.3 mm with a Wide Electron Beam

摘要

A discrete nonlinear theory is used to optimize the efficiency and output power of orotron at a wavelength of 1.3 mm. The device works at the first spatial harmonic of the two-row periodic structure (TRPS) with an increase in the width of electron beam. The dependence of the optimal length of TRPS at which the maximum efficiency is reached for a plane electron beam with a width of three radii of caustic on the plane mirror of the open resonator on the ohmic loss in the TRPS is obtained.
