Efficiency-Optimized Relativistic Oscillators Based on a Corrugated Waveguide

摘要

The efficiency of relativistic Cherenkov oscillators is analyzed using the general equations of excitation of longitudinally irregular waveguides. It is shown that, on the basis of partial optimization of the slowing-system profile of the relativistic backward-wave tube (BWT), its efficiency can reach 40/100 and 60/100 for reflection-type oscillators. In both case the transformation of the forward wave to the backward wave and vice versa in regular and irregular corrugated waveguides is of importance.
