Abstract

In this paper the study of a W-band extended interaction oscillator based on a pseudospark-sourced electron beam will be presented. This new device successfully produced a peak output power of over 38 W, which agrees well with the prediction from the 3D particle-in-cell simulation. It displays the outstanding features of compactness and cost-effectiveness. The main contributing factors include the transport of the electron beam by the positive ion focusing channel without the need of an external guiding magnetic field and high interaction impedance and high gain per unit length of the extended interaction oscillator circuit.
