Abstract

The invention discloses a particle beam image coating used for a spallation neutron source and a preparation method of the particle beam image coating. The particle beam image coating is coated on the outer surface of a front window of a bombarded target, and the main active ingredient of the particle beam image coating is Cr3+doped Al2O3 powder. The preparation method includes coating the Cr3+doped Al2O3 powder on the outer surface of the front window of the target by means of low-power flame spraying to form the image coating. The image coating is developed specially for the spallation neutron source which is a second spallation neutron source using the image coating in the world after an American spallation neutron source is developed. The particle beam image coating is high in light emitting efficiency, using needs on accurately judging beam current distribution and strength at a target position during particle beam bombarding of high-energy proton beam current or ion beam current can be met, and a foundation is laid for further study and development of the spallation neutron source in China.

Description

technical field

[0001] The application relates to the field of particle beam imaging of a spallation neutron source target body, in particular to a particle beam imaging coating for a spallation neutron source and a preparation method thereof. Background technique

[0002] The China Spallation Neutron Source is a major national science and technology infrastructure project. It is a tool to use neutrons to understand the microscopic world; Basic research and high-tech development research in the frontier fields of development and other disciplines provide a new and powerful large-scale scientific research platform. The China Spallation Neutron Source is the first spallation neutron source owned by a developing country. Together with the operating spallation neutron sources of the United States, Japan and the United Kingdom, it constitutes the world's four largest pulsed spallation neutron sources.

[0003] Among them, the neutrons of the spallation neutron source are produce...
