    Abstract: An electron gun (10) that suppresses the non-linear space charge forces and phase-dependant focusing forces that are chiefly responsible for the high emittance of conventional electron guns. The gun comprises a resonant microwave cavity (15), a cathode (12) mounted in the cavity wall, and a momentum analyzer system (17). The resonant microwave cavity, when supplied with microwave power, supports an electromagnetic field having a high-gradient electric component directed along an acceleration axis. The cavity is formed with an exit aperture (32) at a location relative to the cathode such that emitted electrons are accelerated along the axis and pass through the exit aperture. The cavity length is chosen to allow the microwave field within the cavity volume to accelerate the electrons to an energy of about 0.5-1.0 MeV prior to the electrons' passing through the aperture. Bunching is provided by the momentum analyzer. An electron emerging from the cavity has an energy determined by the phase of the microwave field at the time of that electron's emission. Those electrons having energies corresponding to the desired inital phase value are permitted to pass through the momentum analyzer, thereby forming a prebunched electron beam for injection into a linear accelerator.

    Abstract: The invention relates to an electron gun for generating a flat electron beam, comprising a cathode with an emission surface which is curved about a central axis and which is designed to emit electrons. The electron gun further comprises an accelerating device for accelerating the electrons in a radial direction towards a target region on the central axis. Furthermore, the emission surface has a width in the azimuth direction and a height oriented perpendicularly to the width, said width being at least ten times greater than the height.

    Abstract: An emitter device (10) including a focusing array (20) with plural focusing columns (24) to focus emissions from one or more emitters (28) 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 chips are used. The focusing array may be moveable, or in a particularly preferred embodiment, is affixed to the emitter chip, in which case the target medium chip is movable or the focusing array includes beam direction control.

    Abstract: This invention proposes, among other things, systems and methods for providing ozone generators or plasma generators that generate an electric field in an electron generation chamber that is separate from a reaction chamber. An electron beam emitter in an electron generation chamber is configured to emit a beam of electrons and is separated from the reaction chamber by an electron permeable barrier that provides a window through which the beam of electrons passes. The electrons are accelerated to the required energy in the electron generation chamber and transmitted through the barrier to the reaction chamber, where an input gas source introduces an input gas into the reaction chamber. The input gas may react with the beam of electrons inside the reaction chamber to form an output gas comprising a plasma or a concentration of ozone, and the output gas passes from the reaction chamber to a wafer processing chamber.
