Abstract

The invention provides a spallation neutron source target which comprises a target container of a single-layer structure, wherein the target container is provided with a target piece installation cavity, a target window is arranged at the front end of the target container, a cooling liquid inlet and a cooling liquid outlet are formed in the rear end of the target container, a plurality of target pieces are arranged in the target piece installation cavity side by side from the front side to the back side, and cooling liquid flowing gaps are formed between every two adjacent target pieces. The spallation neutron source target is of the single-layer structure, a cooling circuit is formed in the target piece installation cavity by means of the cooling liquid inlet and the cooling liquid outlet, the structure is simple, and machining is easy to achieve.

Description

technical field [0001] The invention relates to a hash neutron source target. Background technique [0002] The spallation neutron source is an important device for studying the microstructure of matter. It can produce a large number of neutrons by bombarding heavy metal targets with high-energy protons, slow down the neutrons and extract them to test the material, and determine the internal structure and dynamics information of the material. At present, only a few countries in the world (the United States, Japan, the United Kingdom, and Switzerland) have spallation neutron source devices. Since protons bombard the target, a large amount of heat will be generated when neutrons are obtained, and it is necessary to cool the target body by cooling liquid. There are generally two types of spallation neutron source targets, one is a liquid target, such as Hg, which is generated by the circulation of mercury itself. It takes away part of the heat, and it is suitable for high-pow...
