    Abstract: In the present invention, a cathode assembly for an X-ray tube is provided including a cathode cup, a pair of emitters disposed within the cup and each configured to emit an electron beam therefrom and an electrode spaced from the pair of emitters and configured to affect the shape and/or intensity of the electron beams emitted by the pair of emitters. The electrode includes a rod extending across a central aperture defined within the electrode that enables the electrode to grid or focus the electron beam or beams emitted from the emitters using a bias voltage between +10 kV and −10 kV.

    Abstract: An emitter device including a focusing array with plural focusing columns to focus emissions from one or more emitters onto a target medium. Relative movement between the target medium and the focused emissions allows each focusing column to focus emissions over an area of the target medium encompassing the movement range. In a preferred embodiment, separate emitter, focusing array and target medium substrates are used. The focusing array may be moveable, or in a particularly preferred embodiment, is affixed to the emitter substrate, in which case the target medium substrate is movable or the focusing array includes beam direction control.
