瞬发γ中子活化分析(PGNAA,Prompt Gamma Neutron Activation Analysis)是一种对物质中的元素成分进行高灵敏、非破坏性分析的方法,以其对某些微量和痕量元素快速,非破坏的分析优点,近年来其应用范围和重要性不断增加。迄今为止,世界上已有30多个实验室建立了瞬发γ中子活化分析(PGNAA)实验装置。中国原子能科学研究院(CIAE)即将建成中国先进研究反应堆(CARR)。CARR是亚洲中子注量率最高的堆,世界第五。利用CARR提供的高品质中子注量率的优势和国际活化分析设施的先进经验、在高起点基础上建立堆热中子瞬发伽玛活化分析应用研究平台。将极大
Prompt Gamma Neutron Activation Analysis (PGNAA) is a highly sensitive and non-destructive method for the elemental composition of matter. It is a rapid and non-destructive method for some trace and trace elements. In recent years, its application and importance have been increasing. To date, more than 30 laboratories around the world have established instantaneous gamma neutron activation assay (PGNAA) experimental setups. China Institute of Atomic Energy (CIAE) is about to complete the China Advanced Research Reactor (CARR). CARR is the heap of the highest neutron flux rate in Asia, the fifth in the world. Taking advantage of the high-quality neutron fluence rate provided by CARR and the advanced experience of international activation analysis facilities, a platform for the application research of heap thermal neutron transient gamma activation analysis was established on the basis of a high starting point. Will be great
