Abstract

The present invention discloses a three-dimensional ionization chamber structure and a ray detection system. The three-dimensional ionization chamber structure is formed by arranging ionization chambers on multiple carriers arranged in a stacked manner. After the multiple carriers form the ionization chamber structure, the ionization chamber forms an arbitrary three-dimensional shape. Compared with the existing surface-mounted three-dimensional ray structure, the three-dimensional ionization chamber structure can set ionization chambers at different depths, thereby forming a real spatial three-dimensional structure, so that the ionization chamber can be fixed at different depths of the carrier to achieve a real spatial distribution, avoiding the defects caused by deducing and correcting with surface data or single depth data. At the same time, this carrier setting method will not limit the number of ionization chambers, can better fit the curved surface, and greatly improve the problem of poor angle response of existing three-dimensional detection equipment. At the same time, its stacked carrier structure is more convenient for industrial mass production, which is conducive to improving production efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of ray detection, and in particular to a three-dimensional ionization chamber structure and a ray detection system. Background Art

[0002] The ionization chamber ray detection structure is mainly used to collect relevant information such as the energy, distribution and state of high-energy rays, and is an important part of radiation measurement equipment. By measuring high-energy rays, effective data information can be obtained, providing an important reference for the industry to use rays.

[0003] At present, the existing ray detection structures are mainly divided into planar two-dimensional detection structures and three-dimensional detection structures. Compared with the three-dimensional detection structure, the two-dimensional detection structure has limitations and cannot meet people's demand for three-dimensional geometric measurement. The existing three-dimensional detection structure generally adopts a surface plug-in surrounding structure, which uses multiple detection plates to be plugged around the center of the detector to form a surrounding detection structure on the detector surface.

[0004] This surface-mounted surrounding structure has no detectors distributed inside, and is not a true three-dimensional structure, because the detectors are only distributed on the surface of the device, that is, it only measures the rays received on the surface, and deduces spatial information through calculation and correction, which is not a true three-dimensional space measurement. In addition, because it can only install detectors on the surface, the number of detectors is limited. Furthermore, when the rays are irradiated around, because the detectors are not fitted to the arc surface, the ray detector receiving surface cannot be completely perpendicular to the rays, resulting in a certain incident angle between the rays and the detector. The disadvantage of poor angle response in arc and spherical structures is more prominent, and there are inevitable defects. Summary of the invention

[0005] The object of the present invention is to provide a three-dimensional ionization chamber structure and a radiation detection system in view of the above-mentioned problems, wherein ionization chambers can be arranged at different depths, and the distribution density of the ionization chambers can be adjusted, thereby forming a true three-dimensional spatial structure, so that the ionization chambers can be fixed at different depth positions of a carrier to thereby achieve true spatial distribution, obtain three-dimensional radiation information, avoid the defects caused by deducing and correcting with surface data or single depth data, and more objectively and truly reflect the three-dimensional radiation data.

[0043] Example 1

[0044] like Figure 1 As shown, this embodiment discloses a three-dimensional ionization chamber structure 100, which is composed of a plurality of carriers 1; a plurality of detection ionization chambers 10 are arranged on each carrier 1; the detection ionization chambers 10 on the plurality of carriers 1 are located on a cylindrical contour line; the plurality of detection ionization chambers 10 on each carrier 1 are located on the envelope diagram of the cross section of the cylindrical contour line along a direction parallel to the carrier 1. In this embodiment, the plurality of detection ionization chambers 10 on each carrier 1 are arranged in a circular ring shape.

[0045] Specifically in this embodiment, a plurality of carriers 1 form a cylindrical shell; the edge of each carrier 1 is an envelope pattern of a cross section of the cylinder along a direction parallel to the carrier 1, that is, see Figure 1 , the edges of each carrier 1 are round.

[0047] The above-mentioned three-dimensional ionization chamber structure 100 is provided with annular ionization chambers 10 on multiple stacked carriers 1. After the multiple carriers 1 form the ionization chamber structure 100, the multiple ionization chambers 10 form a cylindrical shape. Compared with the existing surface-mounted three-dimensional ray structure, the present three-dimensional ionization chamber structure 100 can set the ionization chambers 10 at different depths on a carrier 1, that is, adjust the diameter of the ring formed by the ionization chamber 10, and adjust the distribution density of the ionization chamber 10, thereby forming a real spatial three-dimensional structure, so that the ionization chamber 10 can be fixed at different depths of the carrier 1 to achieve real spatial distribution, obtain three-dimensional ray information, avoid the defects caused by deducing and correcting with surface data or single depth data, and more objectively and truly reflect the three-dimensional ray data. At the same time, this carrier setting method will not limit the number of ionization chambers 10, and the number of ionization chambers 10 is not limited by the size of the surface area, which can greatly increase the number of ionization chambers 10. In addition, the design of the ionization chamber on the carrier of the three-dimensional ionization chamber structure can better fit the curved structural surface, greatly improving the problem of poor angle response of existing three-dimensional detection equipment. At the same time, its stacked carrier structure is more convenient for industrial mass production, which is conducive to improving production efficiency.

[0048] See also Figure 2 In a specific implementation of the present embodiment, the carrier 1 includes a receiving electrode plate 101, a cavity plate 102 and a bias electrode plate 103; the cavity plate 102 is provided with a plurality of cavities 1021; the receiving electrode plate 101 is provided with a plurality of receiving electrodes 1011 corresponding to the cavities 1021; the bias electrode 103 is provided with a plurality of bias electrodes 1031 corresponding to the cavities 1021; the receiving electrode 1011 is located on one side of the cavity 1021; the bias electrode 1031 is located on the other side of the cavity 1021; the receiving electrode 1011, the cavity 1021 and the bias electrode 1031 form a detection ionization chamber 10. Specifically, the radiation detection principle of the detection ionization chamber is a relatively common technical knowledge in the field. Those skilled in the art can refer to the technical description of the prior art for radiation detection using an air ionization chamber to implement the technical solution in the present application. The present application does not intend to improve the principle of radiation detection. Therefore, any implementation of the radiation detection principle should be included in the protection scope of the present application as long as the technical solution in the present application is applied.

[0049] In a specific implementation of this embodiment, the diameters of the circular rings formed by the multiple detection ionization chambers 10 on two adjacent carriers 1 are different. The purpose of this setting is to achieve the staggered positions and detection depths of the ionization chambers 10 on adjacent carriers 1, so as to achieve a more hierarchical design of three-dimensional detection space and detect rays at multiple depths in the three-dimensional space.

[0050] Specifically, one implementation of the above staggered design can be found in Figure 3 , two adjacent carriers 1 are composed of a receiving electrode plate 101, two cavity plates 102 and two bias plates 103; the two cavity plates 102 are respectively arranged on both sides of the receiving electrode plate 101; the two bias plates 103 are respectively arranged on the side of the two cavity plates 102 away from the receiving electrode plate 101. Specifically, receiving electrodes 1011 corresponding to the cavities 1021 on the two cavity plates 102 are respectively arranged on both sides of the receiving electrode plate 101. In this implementation, the diameters of the circular rings formed by the cavities 1021 arranged on the two cavity plates 102 are different, thereby realizing the situation that the diameters of the circular rings formed by the multiple detection ionization chambers 10 on the two adjacent carriers 1 in the above-mentioned staggered design are different. Specifically, the schematic diagram of the receiving electrode 1011 forming circular rings of different diameters is provided on both sides of the receiving electrode plate 101, which can be referred to.

This design only requires that the multiple detection ionization chambers 10 on each carrier 1 be designed to be located at the contour lines of any three-dimensional shape along the envelope figure of the cross section in the direction parallel to the carrier 1. This is not difficult for designers in this field, and they only need to refer to the design method of the above-mentioned three-dimensional ionization chamber structure in this embodiment. Different three-dimensional shapes of ionization chambers are to meet the increasing demand for radiation detection scenarios. According to the cylindrical three-dimensional ionization chamber layout outline disclosed in this embodiment, those skilled in the art can evolve any three-dimensional shape design method based on design common sense to adapt to different radiation detection scenarios. It should be noted that any three-dimensional shape design method should be included in the protection scope of this application.

[0053] Optionally, the shell composed of multiple carriers 1 in this embodiment can be any three-dimensional shape, whether it is a regular three-dimensional geometric shape or an irregular three-dimensional geometric shape.

Different three-dimensional shapes of the shell are to meet the increasing demand for radiation detection scenarios. For example, the internal accommodation space of different radiation detection equipment has different shapes. According to the shell layout outline disclosed in this embodiment, those skilled in the art can evolve any three-dimensional shape of the shell design according to design common sense to adapt to different radiation detection space scenes. It should be noted that any three-dimensional shape of the shell design should be included in the protection scope of this application.
