Abstract :
In this paper, a cylindrical surface wave-hollow electron beam interaction in a special 3-mirror quasi-optical cavity is presented and explored. The study demonstrates THz free electron superradiation from the interaction of cylindrical surface wave and hollow electron beam that forms a resonance within the structure, with the 3-mirror cavity enhancing the intensity of superradiation. The results show that the cylindrical surface wave-hollow electron beam interaction is much stronger than that of planar surface wave and sheet electron beam. Moreover, this system can work in the high-harmonic superradiation region with relatively high efficiency and low current density.
