Abstract

A pseudospark (PS)-sourced electron beam of 3-mm diameter has been experimentally investigated. Emission of X-rays was detected during a PS discharge and clear X-ray images were formed using the PS-sourced electron beam impacting on a 0.1-mm-thick molybdenum target at an applied voltage of 46 kV. Using a phosphor-coated scintillator, the beam's cross-sectional profile and surrounding ion channel were also observed. These results confirm the presence of an electron beam.
