Abstract
A 2.5D hybrid model is used to numerically study the interaction of a beam with a current of 2.5–7.5 kA and an electron energy of 345–510 keV and terahertz (364–368 GHz) electromagnetic field. It is shown that Bragg reflectors in an electrodynamic system with an overmode ratio of 49 make it possible to significantly suppress backward radiation and multiply increase the radiation power in the direction of the electron beam. Radiation pulses with a power of up to 330 MW are obtained in calculations with disregard of heat loss in the presence of a guiding magnetic field of 6 T.
