ABSTRACT:
System that focuses electron beams in an electro-static area to a laminar flow of electrons with uniform distribution of current density and extraordinary demagnification includes a body that defines a boundary for an electric field, a field-forming cathode electrode system, a focusing electrode system, and at least one anode electrode system in the electro-static section and a second electric field-free section including an adjustable screen system arranged in an interior of the body. The field-forming near-cathode electrode system includes a cathode electrically connected to a flat part and a curvilinear part electrically connected to a cylindrical part. The anode electrode system includes an opening part, an anode electrically connected to a flat part and a curvilinear part electrically connected to a cylindrical part which is similar or identical to and symmetrical with the cathode electrode system. The system parameters are calculated and created due to the CGMR conceptual method.
