    Abstract

    In this paper, a three-cavity klystron upconverter operating at W-band is presented. It is predicted to generate 40 W when driven by a 30 kV, 0.2 A electron beam. Pseudosparksourced electron beam after post-acceleration was proposed to be used with the klystron upconverter because it has the advantage of low energy spread, high current density, and no need of any external guiding magnetic field.
