Abstract

A neutron tube target structure with an adjustable target distance comprises a target insulator, the outer side of the target insulator is connected with the outlet side of a Faraday cup in an embedded mode, the two ends of the inner side of the target insulator are connected with one ends of screws respectively, and the other ends of the two screws vertically penetrate through the two ends of a baffle respectively to be connected with nuts in a matched mode. A corrugated telescopic tube is connected between the target insulator and the baffle, the inner side of the baffle is connected with a fixed end of a pull rod, and a free end of the pull rod penetrates through an inner cavity of the corrugated telescopic tube to be connected with the target; by adjusting the positions of the nuts on the screws, the corrugated telescopic tube is driven to stretch out and draw back, and the baffle can be driven to reciprocate along the axial direction, so that the target is driven by the pull rod, the distance between the target and the Faraday cup is adjustable, the range of ion beams hitting the surface of the target is enlarged, the number of ions participating in reaction is increased, the utilization rate of the target is improved, and the neutron yield is increased. The Neutron tube target structure has the advantages of simple structure, convenience in operation, practicability and high efficiency.

Description

[0001] The invention relates to the technical field of neutron tubes, in particular to a neutron tube target structure with adjustable target distance. Background technique [0002] At present, the working principle of most neutron tubes is that the ions generated from the plasma region are extracted from the extraction hole, accelerated by the Faraday cylinder, hit the target on the surface of the target, and form neutrons after reaction. However, since the ions coming out of the accelerating tube are in a beam shape, and the distance between the accelerating tube and the target is fixed, it largely affects the area of ​​the ion beam hitting the target, and the neutrons produced by the reaction will be relatively small. less, resulting in a relatively low utilization rate of the target. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a neutron tube target structure w...
