The effect of the electron-beam parameter spread on microwave generation in a three-cavity axial vircator

TL;DR

This paper investigates how variations in electron-beam parameters affect the efficiency and spectrum of microwave generation in a three-cavity axial vircator, identifying optimal conditions and parameter ranges for maximum performance.

Contribution

It determines the optimal electron-beam parameters for different vircator geometries and establishes the tolerance ranges for efficient microwave generation.

Findings

Optimal beam radius, impedance, and energy homogeneity maximize efficiency.

Efficiency peaks at specific parameter values for each resonator geometry.

Parameter variations within certain ranges do not significantly reduce generation efficiency.

Abstract

The behavior of the generation efficiency and radiation spectrum of a three-cavity axial vircator versus the radius of the injected electron beam, its impedance and energy homogeneity is studied. This paper establishes that for each geometry of a three-cavity resonator, there exist the optimal (maximizing the generation efficiency) values of these parameters and determines the range within which they may vary without losing the efficiency of generation.
