Gas-filled neutron tube with inertial ion confinement

摘要

The utility model relates to plasma technology, to devices for generating neutrons and can be used for nuclear physics research, in inspection systems, for calibrating ionizing radiation detectors, etc. The technical result is an increase in the life of the neutron tube. that a gas-filled neutron tube with inertial ion confinement containing a first cylindrical insulating body made of a dielectric material is hermetically sealed the first hollow end electrode with a through hole connected to its end, the first source of Pening ions, hermetically connected to the first hollow end electrode from the opposite side to the first cylindrical insulating housing, the first annular permanent magnet mounted on the first source of Penning ions coaxially with and adjacent to it the first hollow end electrode, the working gas storage located inside the first source of Pening ions, the second cylindrical insulating body, made made of dielectric material, a second hollow end electrode with a through hole, hermetically connected to the end face of the second cylindrical insulating body, a second source of Pening ions, hermetically connected to the second hollow end electrode from the opposite side relative to the second cylindrical insulating body, the second annular permanent magnet mounted on the second source of Pening ions is coaxial with it and close to the second hollow end electrode; additionally contains a hollow accelerating electrode, hermetically connected to the ends of the cylindrical insulating housings on opposite sides relative to the hollow end electrodes, an additional annular permanent magnet mounted on the hollow accelerating electrode in the middle between the cylindrical insulating housings; cylindrical insulating bodies have the same geometry; hollow end electrodes have the same geometry; through holes have the same geometry; sources of Penning ions have the same geometry, except that the working gas storage located inside the first source of Penning ions; ring permanent magnets have the same geometry; an additional annular permanent magnet, cylindrical insulating bodies, hollow accelerating and hollow end electrodes, holes, sources of Pening ions and ring permanent magnets are located coaxially; cylindrical insulating bodies, hollow end electrodes, holes, sources of Penning ions and ring permanent magnets are located symmetrically with respect to the hollow accelerating electrode; hollow accelerating and hollow end electrodes are figures of rotation around the central axis of a gas-filled neutron tube and have cavities near the axis; a hollow accelerating electrode is symmetrical about its center. 1 ill.
