Description

The nonlinear beam-wave interaction in coupled-cavity TWT working in plasma-cavity hybrid mode was studied using the theory of mode expansion, and the nonlinear beam-wave interaction self-consistent working equations have been obtained. The space-charge field with plasma-background was analyzed using the Green's function. A simulation program has been programmed to analyze the nonlinear characteristics in the plasma-cavity hybrid mode coupled-cavity TWT, such as the gain, efficiency, output power. The results show that the warm bandwidth can reach (20-30)% and the efficiency can be more than 50% in coupled-cavity TWT working in plasma-cavity hybrid mode. (authors)
