[0002] Neutron testing is a technology that uses neutrons to detect and analyze matter. Neutron non-destructive testing refers to a testing method that uses neutron rays to interact with matter without destroying the structure and morphology of the object being tested to obtain the internal microscopic and macroscopic structure and material information of the material, and evaluates the microscopic and macroscopic defects, geometric characteristics, chemical composition, organizational structure, mechanical properties and changes of materials or parts.

The upper side of the base is a sample placement area. A cavity for installing the neutron emission source is arranged in the middle of the base. The cavity runs through the upper side of the base. The shielding cover is arranged on the upper side of the base. The position of the shielding cover can be adjusted in the up and down directions. The neutron imaging detector is arranged on the upper side of the shielding cover; the shielding cover is a conical tube structure with a small upper part and a large lower part, and also includes a shielding tube.
