Diffraction radiation generator with magnetic inhomogeneity

Abstract

ABSTRACT We experimental show that output characteristics ofnon-relalivistic Diffraction Radialion Generator (DRG) are greatlyperfected when we create alocal inhomogeneity offocusing magnetostalical field in the interaction space ofelectronic beam.We conclude that it is perspective to use a thick electron beams in the DRG ofSubMM frequency range. 1. INTRODUCTION The Smith - Purceli effect1'2 slimulated a progress in the electronics of MM and SubMM band range in differentcountries. In Ukraine the possibility of Smith - Purcell effect utilization in the electronics have been studied since 1963.Currently in IRE NASU on this principle there is proposed, created and explored a complex ofnew non-relativislic sourcesofelectromagnelic oscillations, named by the Diffraction Radiation Generator (DRG) These types ofgenerators include apassed DRG, a reflective DRG, a pulsed DRG and other devices. Some types of that generators was named Orotron andFree-electron laser in some couniries . DRG works in 30 -
