Abstract

The invention discloses a three-dimensional ionization chamber structure and a ray detection system. According to the three-dimensional ionization chamber structure, ionization chambers are arranged on a plurality of stacked carriers; after the plurality of carriers form an ionization chamber structure, the ionization chamber forms any three-dimensional shape; compared with an existing surface plug-in mounting type three-dimensional ray structure,, the ionization chamber can be arranged at different depths, so that a real spatial three-dimensional structure is formed; the ionization chamber can be fixed at different depth positions of a carrier to realize real spatial distribution, and defects caused by deduction and correction by surface data or single depth data are avoided. Meanwhile, the carrier arrangement mode does not limit the number of the ionization chambers, the ionization chambers can be better attached to the arc-shaped surface, the problem that existing three-dimensionaldetection equipment is poor in angle response is well solved, the carrier structure designed in a stacked mode is more convenient for industrial batch production, and the production efficiency can bebetter improved.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a three-dimensional ionization chamber structure and a radiation detection system. Background technique [0002] The ionization chamber ray detection structure is mainly used to collect relevant information such as energy, distribution and state of high-energy rays, and is an important part of radiation measurement equipment. Through the measurement of high-energy rays, effective data information can be obtained, which provides 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 three-dimensional detection structures. Compared with the three-dimensional detection structure, the two-dimensional detection structure has limitations, and cannot meet people's measurement requirements for solid geometry. However, the existin...
