Theory of Multicavity Gyroklystron Amplifier Based on a Green's Function Approach

摘要

This report presents an application of a self-consistent field theory for gyrotrons to a multicavity gyroklystron configuration. The coupled radio frequency field equation and the Lorentz equations are solved in the slow-time scale formulation by using a Green's function technique to satisfy appropriate boundary conditions. An analytical expression for the small signal gain is obtained by successive approximation. The theory has been developed for cylindrical TE sub mnl mode as well as rectangular sub 101 mode. The theory is applied to calculate the small signal performance characteristics of a three-cavity configuration operating with rectangular TE sub 101 mode.
