    摘要: Vacuum electron devices (VEDs) are produced having a plurality of two-dimensional layers of various materials that are bonded together to form one or more VEDs simultaneously. The two-dimensional material layers are machined to include features needed for device operation so that when assembled and bonded into a three-dimensional structure, three-dimensional features are formed. The two-dimensional layers are bonded together using brazing, diffusion bonding, assisted diffusion bonding, solid state bonding, cold welding, ultrasonic welding, and the like. The manufacturing process enables incorporation of metallic, magnetic, and ceramic materials required for VED fabrication while maintaining required positional accuracy and multiple devices per batch capability. The VEDs so produced include a combination of magnetic and electrostatic lenses for electron beam control.

    摘要: In an electron irradiation system, a gas-tight housing encloses a cathode region and an irradiation region, which communicate through at least an aperture. In the cathode region, there is arranged a high-voltage cathode for emitting an electron beam. In the irradiation region, there is an irradiation site arranged to accommodate a stationary or moving object to be irradiated. The migration of cathode-degrading debris is limited by means of an electric field designed to prevent positively charged particles from entering the cathode region via the aperture. The invention can be embodied with an axial electric field, which realizes an energy threshold, or a transversal field which deflects charged particles away from trajectories leading into the cathode region.
