Time-Dependent Computer Analysis of Electron—Wave Interaction in Crossed Fields

Abstract

A time‐dependent analysis of crossed‐field interaction has been formulated for computer calculation. The computer program has achieved, for the first time, accurate and complete simulation of the magnetron oscillator, magnetron amplifier, and smooth‐bore magnetron. We believe that crossed‐field interaction of the distributed‐emission type is finally predictable. The computer results are reliable enough to serve as design information. They also indicate that the nature of the interaction is turbulent in the sense that the operation of these devices borders between order and disorder under certain conditions. The techniques used in this analysis are applicable to a wide range of problems dealing with other types of electron—wave interaction, and to plasmas.
