Abstract

This paper presents the design and simulation of a 390 GHz harmonic gyrotron operating with a TE 71 mode at the 7 th electron cyclotron harmonic of a large orbit electron beam from a cusp electron gun. The electron beam has an energy of 40 keV, beam current of 1.5 A, an adjustable pitch alpha from 1 to 2 with a minimum beam velocity spread and scalloping in the beam trajectory. Interaction region based on cylindrical waveguide with smooth inner surface and slotted structures have been studied. Theoretical analysis and numerical simulation results of this source operating at THz frequencies are presented.
