摘要

In the paper, an overview of investigation results of three-centimeter wavelength range multiwave Cerenkov generators (MWCG) with different slow-wave structure (SWS) geometry is presented. Theoretical and experimental investigations of MWCG with a two-sectional SWs allowed to distinguish several generation regimes due to nonlinear interaction of TM_(0.1)-mode longitudinal resonances. It is shown that the use of SWS with nonuniform sections allows to increase generation efficiency, to expand the region of parameters for stable generation, to reduce the influence of the gap between the beam and SWS on the ouput power, to narrow radiation spectrum. We associate further progress with development of new methods to control spatial-temporal topology of electromagnetic field in overmoded sectionalized SWS.
