    Abstract: An electron beam emitter including a vacuum chamber having a width. An electron generator can be positioned within the vacuum chamber for generating electrons. An elongate nozzle can extend from the vacuum chamber along a longitudinal axis and have an exit window at a distal end of the nozzle. The nozzle can have a width that is less than the width of the vacuum chamber. The electron generator can be shaped and dimensioned, and positioned with the vacuum chamber to form and direct a narrow electron beam that enters and travels through the nozzle, and exits out the exit window.

    Abstract: An electron beam irradiator capable of performing electron beam irradiation in a wide area at a high current density with a field emitter tip. The electron beam irradiator comprises: a vacuum chamber having a beam irradiation window formed longitudinally in an outer periphery of the vacuum chamber; a cathode placed centrally and longitudinally inside the vacuum chamber, and having a field emitter tip formed on the cathode, corresponding to the beam irradiation window; and a high voltage supply placed at one end of the vacuum chamber, and adapted to apply high voltage toward the cathode. The electron beam irradiation can be made in a wide area without using an electromagnet as well as in a high current density without using a heater such as a filament or an additional power supply, thereby to ensure a simplified structure as well as a reduced size.

    Abstract: An electron accelerator includes a vacuum chamber having an electron beam exit window. The exit window is formed of metallic foil bonded in metal to metal contact with the vacuum chamber to provide a gas tight seal therebetween. The exit window is less than about 12.5 microns thick. The vacuum chamber is hermetically sealed to preserve a permanent self-sustained vacuum therein. An electron generator is positioned within the vacuum chamber for generating electrons. A housing surrounds the electron generator. The housing has an electron permeable region formed in the housing between the electron generator and the exit window for allowing electrons to accelerate from the electron generator out the exit window in an electron beam when a voltage potential is applied between the housing and the exit window.

    Abstract: An electron beam device has a cathode that generates a fan-shaped electron beam. A first focusing lens includes first and second plates on opposed sides of a filament. The edges of the plates closest to a positively charged anode are arcuate, so that as individual electrons are accelerated normal to the edge of the charged plates, the beam increases in length with departure from the filament. A second focusing lens includes third and fourth plates on opposed sides of the first focusing lens. Each of the third and fourth plates has an arcuate edge proximate to the positively charged anode. The plates of the first and second focusing lenses provide focusing in a widthwise direction, while defining the increase in the lengthwise direction. Preferably, the filament is also curved. In the preferred embodiment, the curvature of the plates of the first focusing lens defines a common radius with the plates of the second focusing lens. The electron beam may be projected from the interior of an evacuated tube and may have a length that is not limited by the length of the filament.
