中科院团队研发新型闪烁屏 突破快中子成像分辨率瓶颈

Core Viewpoint - Fast neutron radiography technology has significant potential in detecting internal defects in large and high-density equipment, such as aircraft engines, but its resolution limitations hinder broader application [1] Group 1: Technology Development - The research team from the Chinese Academy of Sciences has developed a high-transparency glass scintillator screen using a solvent-free melting quenching method [1] - The new scintillator screen has a transmittance exceeding 70% and a light output three times that of commercially available scintillator screens of the same thickness, significantly enhancing spatial resolution in fast neutron imaging [1] - The preparation strategy allows for the production of large-area scintillator screens with controllable shapes and good toughness, providing a foundation for replacing traditional fast neutron scintillator screens [1] Group 2: Industry Impact - This research significantly improves the applicability of fast neutron imaging and is expected to advance the development of non-destructive testing technologies for large equipment [1] - The findings were published in the international academic journal "Nature Communications," indicating recognition within the scientific community [1]
