    Abstract: The present invention is directed to a particle beam processing apparatus that is smaller in size and operates at a higher efficiency. The processing apparatus includes a particle beam generating assembly, a foil support assembly, and a processing assembly. In the particle beam generating assembly, a cloud of particles, for example, electrons, are generated by heating at least one tungsten filament. The electrons are then extracted to travel at a high speed to the foil support assembly which is set at a much lower voltage than the particle beam generating assembly. A substrate is fed to the processing apparatus through the processing zone and is exposed to the electrons exiting the particle beam generating assembly and entering the processing zone. The electrons penetrate and cure the substrate causing a chemical reaction, such as polymerization, cross-linking, or sterilization.

    Abstract: The present invention is directed to a particle beam processing apparatus that is smaller in size and operates at a higher efficiency, and also directed to an application of such apparatus to treat a coating on a substrate of a treatable material, such as for flexible packaging. The processing apparatus includes a particle beam generating assembly, a foil support assembly, and a processing assembly. In the particle beam generating assembly, electrons are generated and accelerated to pass through the foil support assembly. In the flexible packaging application, the substrate is fed to the processing apparatus operating at a low voltage, such as 110 kVolts or below, and is exposed to the accelerated electrons to treat the coating on the substrate.

    Abstract: An ion plasma electron gun for the generation of large area electron beams with uniform electron distribution. Positive ions generated by a wire in a plasma discharge chamber are accelerated through an extraction grid into a second chamber containing a high voltage cold cathode. These positive ions bombard a surface of the cathode causing the cathode to emit secondary electrons which form an electron beam. After passing through the extraction grid and the plasma discharge chamber, the electron beam exits from the gun by way of a second grid and a foil window supported on the second grid. The gun is constructed so that the electron beam passing through the foil window has a relatively large area and a uniform electron distribution which is substantially the same as the ion distribution of the ion beam impinging upon the cathode. Control of the generated electron beam is achieved by applying a control voltage between the wire and the grounded housing of the plasma chamber to control the density of positive ions bombarding the cathode.
