Radiation shaping shielding device

Technical Field

The utility model relates to the technical field of radiation shaping.

Background

In the field of nuclear technology utilization, high-energy particles or laser are often required to be used for targeting to generate new radiation source items, such as spallation neutrons generated by high-energy proton targeting, X rays generated by electrons passing through tungsten targets, and coherent X rays and gamma rays generated by free electrons striking ultrashort laser targets, so as to be used for diagnosis, treatment or nuclear science research experiments. The radiation source produced by the high energy particle targeting is typically isotropic. In general, only radiation beams in a certain direction and at a certain opening angle are useful, and radiation sources in other directions are useless and harmful, so that for collimation and focal spot shaping of the beams, a shielding body with a certain shape is designed to serve as a target cavity, a target piece is placed in the target cavity, an opening is reserved only in the high-energy particle entering direction and the utilization direction of the radiation source after shooting, an opening arranged in the utilization direction of the radiation source forms a certain opening angle with a target point, and the radiation source can only emit in a certain direction in the opening angle, so that focal spot shaping and collimation are realized.

The high-energy particles are generally transported in the vacuum tube, the target generally acts with the high-energy particles in the vacuum tube, the target can be activated to have radioactivity in many cases, the target needs to be replaced after being used for a period of time, when the target needs to be replaced, workers cannot approach to the operation, the target on the vacuum tube in the target cavity needs to be replaced by remote operation through equipment, the inner space of the target cavity is often narrow and limited by the fact that the target extends from the inlet of the target cavity, and the operation of the machine in the target cavity is very difficult.

Disclosure of Invention

In view of the above, the present utility model provides a radiation shaping shield that can more conveniently replace a target.

In order to achieve the above purpose, the present utility model provides the following technical solutions.

The radiation shaping shielding device comprises a target shielding body, wherein a target cavity for placing a target is formed in the hollow of the target shielding body, the target shielding body comprises at least two shielding combination blocks, the at least two shielding combination blocks are spliced to form the target shielding body and the target cavity thereof, the splicing surfaces among the shielding combination blocks are curved surfaces in a bending manner, and the shielding combination blocks can be dispersed to enable the target shielding body and the target cavity thereof to be disassembled so as to facilitate replacement of the target. This is claim 1.

The target shielding body and the target cavity are formed by splicing at least two shielding combination blocks, and each shielding combination block can be dispersed to enable the target shielding body and the target cavity to be disassembled, so that a vacuum tube and a target in a narrow target cavity are exposed, the target can be conveniently operated and replaced at the moment, and the machine is not limited by the fact that the machine stretches into the narrow space of the target cavity from an inlet of the target cavity.

On the basis of the technical scheme 1, two shielding combination blocks are arranged left and right and can move left and right along the horizontal direction so as to complete the splicing or the disassembly of the target shielding body and the target cavity thereof. The material and the size of the target shielding body determine that the target shielding body has great weight, the splicing of the target shielding body and the target cavity thereof is completed by the two shielding combination blocks which are arranged left and right and can move left and right along the horizontal direction, the operation is convenient, and the left and right movement of the heavy shielding combination blocks is more labor-saving compared with the movement of moving the heavy shielding combination blocks up and down. This is claim 2.
