Effect of delayed reflection from the remote load on mode competition in а gyrotron

Autors: 
Chumakova Marija Mihajlovna, Saratov State University
Abstract: 

Effect of reflection from the remote load on the mode competition in a two-mode electronic maser is considered. A system of quasilinear equations for slowly varying amplitudes of the modes with cubic nonlinearity where the effect of reflections is taken into account by time delayed terms is analyzed. The most typical case of competition of two modes with close frequencies at the centre of generation zone is studied in detail. Change of generation regimes with increasing of reflections of the spurious mode at different values of delay is investigated analytically and numerically.
