Intense steady-state neutron generation device

Abstract

The invention discloses an intense steady-state neutron generation device comprising a vacuum differential system, a throttling pipeline, a linear target pipe and a solid-state target disk device sequentially arranged in a movement direction of a beam current; the linear target pipe is used for realizing a reaction between the beam current and a gaseous medium; the solid-state target disk device is used for realizing a reaction between the beam current and a solid-state medium; and two ends of an internal cavity of the linear target pipe are respectively connected with the throttling pipelineand a solid-state target disk chamber of the solid-state target disk device in a sealing way. In an intense neutron source continuous production device provided by the application, the solid-state target disk device is mounted at the rear of a linear target disk, a point neutron source is produced in the solid-state target disk device after a linear neutron source is produced in the linear targetdisk, and the condition that the linear target pipe is isolated due to the arrangement of the vacuum differential system, so that the linear neutron source, the point neutron source and relatively high neutron source intensity are stably produced.

Description

technical field [0001] The invention relates to the technical field of deuterium-tritium neutron source generation, in particular to a continuous generation device for a high-current neutron source. Background technique [0002] The accelerator-type deuterium-tritium fusion neutron source uses a strong deuterium ion beam to bombard a tritium target to produce a deuterium-tritium fusion reaction to produce 14MeV high-energy fusion neutrons. [0003] The traditional deuterium-tritium fusion neutron source basically uses a solid-state target disk device, that is, the reaction substance deuterium or tritium is fixed and adsorbed in the film on the solid-state target metal surface of the solid-state target disk device, and the target is bombarded by a deuterium beam to generate deuterium-deuterium or deuterium Tritium reaction. Because the beam of a certain energy bombards the surface of the solid target, the penetration depth is only a few microns, and the point source is the s...

Problems solved by technology

[0004] When the line neutron source and the point neutron source are set separately, due to the high heat flux deposited on the solid surface by the beam with too high energy in the point neutron source, and the excessively high target chamber pressure required by the high source intensity in the line neutron source It will cause difficulties in the transmission of high-energy beams. Therefore, the achievable neutron source intensity of a single line neutron source and point neutron source is limited.

[0005] At the same time, when it is necessary to generate line neutron sources and point neutron sources, independent equipment needs to be set up to perform the above operations, and the operation is cumbersome
