The paper presents an application of a self consistent field theory for gyrotrons to a multicavity gyroklystron configuration. The coupled RF field equation and the Lorentz equations are solved in the slow-time-scale formulation using a Green's function technique to satisfy appropriate boundary conditions. An analytical expression for the small-signal gain is obtained by the method of successive approximation. The theory has been developed for cylindrical TE▪ mnl mode as well as rectangular TE101, mode. The theory is applied to calculate the small-signal performance characteristics of a three-cavity configuration operating with rectangular TE101 mode.
