Abstract: A plurality of strip filaments provide a source of electrons. A deflector electrode in the form of a flat dish is placed behind the filaments, and director electrodes which may be in the form of wire meshes, are placed forward of the filaments in the direction in which the electron flow is desired. Additional electrodes which may be in the form of narrow plates are placed along the ends of the filaments to compensate for fall-off in emission at the filament extremities. The various electrodes are positioned relative to the filaments and have potentials applied thereto such that the uniform distribution of electrons is provided over a predetermined area throughout which electron flow is desired.
