Abstract :
Summary form only given. The purpose of this work is to theoretically understand what are the possible noise levels in a magnetron or a crossed-field amplifier, due to parametric three-wave interactions in the electron plasma, at various operating parameters. Our approach is to use the cold-fluid equations and their Fourier decomposition into a background (DC) mode, a pump (RF) mode, and two other noise (RF) modes. The two RF noise modes are assumed to interact parametrically with the large RF pump mode, and to satisfy the standard resonance conditions for the sum of the wavevectors and sum of the frequencies.
