ELECTRON BEAM GENERATOR (VERSIONS) Russian patent published in 2014 - IPC H05H1/24 

FIELD: electricity.

SUBSTANCE: in the first version of the invention the generator cathode (1) is made as an uncooled cylinder inserted tightly to an isolator (2). In the butt end the isolator has an opening coaxial to the cathode and right up to the isolator butt end a flat metal anode (3) is installed with opening coaxial to the isolator opening thus forming a channel for an electronic beam from the cathode butt end up to the generator output. In the second version the electron beam generator comprises a discharge structure placed directly in the working gas, which consists of a cathode, and isolator and anode; the generator cathode is made as an uncooled cylinder, the butt end of the isolator is placed in the same plane with the cathode butt end, right up to the isolator butt end, coaxially with the cathode, there is a washer, which inner diameter is mode than the cathode diameter and right up to the washer there is a flat metal anode with an opening coaxial to the washer thus forming a channel for an electronic beam from the cathode butt end up to the generator output. Both in the first and second versions the cathode may be fixed in the isolator by adhesive bond far from the cathode working surface.

EFFECT: ensuring cooling of the cathode and isolator close to the beam output and reaching higher operating parameters such as gas pressure, voltage and power.
