Abstract

Experimental results of two extended interaction oscillators (EIOs) based on a planar slow wave structure (SWS) and a pseudospark-sourced sheet electron beam (PS-SEB) are presented. Initial experimental results demonstrated that the 0.1 THz and 0.2 THz EIOs could provide an output power of 1.2 kW and 10 W, respectively. The idea of combining the advantages of a PS-SEB (high beam current density and large beam cross-sectional area) and a planar SWS (high gain per unit length) to generate powerful terahertz radiation was experimentally verified. Such a methodology provides a possible solution to achieve room-temperature operation, compact, low cost and high output power radiation sources.
