Power and Efficiency Enhancement of the Reltron Using Dual RF Output Cavities

Abstract

In this paper, a dual RF output cavity based reltron is proposed to enhance the efficiency as well RF output power. It uses two RF output cavities of different quality factor. The quality factor of the first output cavity kept low whereas the quality factor of the second output cavity is kept higher. The output cavity with low quality factor extracts maximum RF output power whereas the second output cavity with has higher quality factor extracts remaining output power. With typically selected electrical parameters, the proposed reltron delivers ~ 270 MW output power with ~ 42.4% efficiency. The obtained results show the improvement in the device performance in terms of RF output power as well as efficiency as compared to the conventional reltron.
