西安加速器质谱中心拥有的一台3MV的分析多核素的加速器质谱仪(Xi’an-AMS)是我国地学、考古、生物医学及其它运用AMS技术领域的一个实验平台。本文介绍四个核素(10Be、14C、26Al和129I)验收达到的先进水平,特别是测得14C/12C测量精度为0.2%,10Be/9Be最小比值为3.65×10-15。本文还介绍了该AMS的主要技术特点。
The Institute of Earth Environment of the Chinese Academy of Sciences and Xi'an Jiaotong University have jointly created an AMS center, under the support of Ministry of Science and Technology, Chinese Academy of Sciences and Ministry of Education. The Xi’an 3MV multi-element AMS system will be a national experimental platform for earth environmental studies, archeology, biomedical research and other fields related to the AMS technique. This paper describes the AMS’s major components with their unique featur...
