    Abstract: Es wird eine Elektronenstrahleinheit beschrieben, die dazu ausgelegt ist, ein flächig ausgedehntes Bestrahlungsfeld zur Elektronenbestrahlung von Bestrahlungsgut zu erzeugen. Das Bestrahlungsgut ist in einer vorgegebenen Transportrichtung durch das Bestrahlungsfeld führbar, und das Bestrahlungsfeld erstreckt sich über eine Bestrahlungsbreite quer zur Transportrichtung. Die Elektronenstrahleinheit umfasst eine Mehrzahl von Heizkathodendrähten zur Erzeugung von Elektronen, wobei die Heizkathodendrähte oberhalb des Bestrahlungsguts entlang der Bestrahlungsbreite der Elektronenstrahleinheit angeordnet sind und wobei die Heizkathodendrähte parallel zueinander ausgerichtet sind. Die Elektronenstrahleinheit umfasst außerdem mindestens ein Gitterelement, das dazu vorgesehen ist, die Elektronen von den Heizkathodendrähten abzuziehen, zu verteilen und zu beschleunigen, sowie ein Elektronenaustrittsfenster, aus dem die Elektronen nach der Beschleunigung austreten. Die Heizkathodendrähte sind relativ zur Transportrichtung um einen vorgegebenen Winkel verdreht ausgerichtet sind, wodurch sich ein schräger Verlauf der Heizkathodendrähte relativ zur Transportrichtung ergibt.

    Abstract: An electron accelerator (10) includes a vacuum chamber (46) having an electron beam exit window (24). An electron generator (31) is positioned within the vacuum chamber for generating electrons. A housing (30) surrounds the electron generator and has a first series of openings (34) 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. The housing also has a second series and third series of openings (35) formed in the housing on opposite sides of the electron generator for causing electrons to be uniformly distributed across the electron beam by flattening electrical field lines between the electron generator and the exit window.

    Abstract: The invention provides 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. According to the invention, 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.
