| 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 $\mathbf{2.0}\mathbf{mm}\times \mathbf{0.25}\mathbf{mm}$ is used in the sheet beam generation and propagation experiments. Sheet beam currents in the range of 6A to 21 A (~ $\sim 10^{4}\mathrm{A}/\mathrm{cm}^{2}$ 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 $2.8\mathbf{mm}\times 0.5\mathbf{mm}$ and $\mathbf{1.0 \ mm}\times \mathbf{0.17 \ mm}$ in cross sectional size respectively. |
