中文摘要: 中子成像作为一种快速、直观的无损检测技术,在核工业、航空航天、新能源、地质、考古、先进制造等多个领域得到广泛应用。中子成像利用中子不带电、穿透能力强、对轻元素敏感、可区分同位素和近邻元素等特性,非常适合开展含氢元素、近邻元素和同位素等材料的无损检测。本文概述了中子成像技术的基本原理及特点,并结合中国先进研究堆(CARR)中子成像装置上的应用案例, 重点介绍了国内外中子成像技术在储氢材料、燃料电池、岩石、核燃料元件、古代文物等领域的典型应用。随着中子成像技术的不断发展和广泛应用,有望为我国更多领域研究提供更强有力的技术支撑。
Abstract:As a non-destructive testing technique, neutron imaging has been widely used in various fields, including nuclear industry, aerospace, new energy, geology, archaeology, and advanced manufacturing. This technique leverages the unique characteristics of neutrons, such as their neutral charge, strong penetration capability, sensitivity to light elements, and ability to differentiate isotopes and neighboring elements, making it particularly suitable for non-destructive analysis of materials containing hydrogen, neighboring elements, and isotopes. This review provides an overview of the fundamental principles and characteristics of neutron imaging, and highlights the typical applications of neutron imaging technology in diverse areas, including hydrogen storage materials, fuel cells, geological specimens, nuclear fuel components, and ancient artifacts. The relevant application examples from both international and China Advanced Research Reactor (CARR) neutron imaging facility are also presented.With the ongoing development and application of neutron imaging technology, it is expected to provide more robust technical support for domestic research in various fields.
