Abstract

This paper presents the plasma-sourced sheet electron beam generation based on a pseudospark discharge. This beam source has advantages of high current density, ion-channel assisted beam focus, long life and simplicity with no external guiding magnetic field needed for beam transportation. A collimator of cross section size of 2.0mm × 0.25mm is used in the sheet beam generation and propagation experiments. Sheet beam currents in the range of 6A to 21 A (~104 A/cm2 current density) and peak voltage of ~32 kV were measured after the sheet beam has propagated a distance of 10-mm without any external focusing magnetic field. Furthermore the pseudospark-sourced sheet electron beams were successfully used to drive both a W-band (75-110 GHz) and a G-band (200 GHz) planar extended interaction oscillator (EIO), with beam tunnel of approximately 2.8mm × 0.5mm and 1.0 mm × 0.17 mm in cross sectional size respectively.
