Abstract

The invention discloses a high-current ion beam accelerating tube applied to a fusion reaction high-current accelerator neutron source. The high-current ion beam accelerating tube consists of a plurality of insulating ceramic rings, stainless steel vacuum sealing flanges, cylindrical shielding electrodes, accelerating electrodes, O-shaped vacuum sealing rings arranged in grooves in the end faces of the ceramic rings, and O-shaped buffering rings arranged in grooves in the circumferential outer edge surfaces of the ceramic rings; and adjacent insulating ceramic rings are fixed together by using compression rings, bolts and nuts. By adopting the high-current ion beam accelerating tube, the vacuum sealing problem of a large-diameter high-current accelerating tube is solved, the practical vacuum degree inside the accelerating tube can be up to 10<-5>Pa, and meanwhile the defects of low tensile strength, easiness in leaking air, low vacuum degree and the like in the accelerating tube caused by the application of an insulating glue bonding technology in the prior art can be completely overcome.

Description

technical field [0001] The invention relates to a high-current ion beam accelerating tube used for a neutron source of a fusion reaction high-current accelerator. Background technique [0002] Intensive deuterium-deuterium (D-D) and deuterium-tritium (D-T) fusion reaction accelerator neutron sources are important single-energy neutron sources, which can be widely used in nuclear data measurement, nuclear fusion reactor basic research, military basic research and other aspects. The basic principle of this neutron source is to use a double-pressure high-pressure accelerator to accelerate deuterium (D) ion beams to hundreds of keV energy, and bombard deuterium-titanium (TiD) targets or tritium-titanium (TiT) to generate deuterium-deuterium (D-D) and deuterium-tritium (D-T) Fusion reactions produce fast neutrons. [0003] The yield of fast neutrons is proportional to the intensity of the D beam accelerated and bombarded on the target. In order to realize the D-D reaction fast ...
