国产小型加速器质谱仪及其应用前景

The Homemade Compact Accelerator Mass Spectrometry and It’s Applications

    摘要
  • 摘要: 广西师范大学小型加速器质谱系统(GXNU-AMS)于2017年底圆满建成并投入使用，是我国首台自行研制的单极专用AMS装置，也是目前设计能量最低的AMS装置之一。该装置采用150 kV端电压，氦气剥离，选择+1电荷态测量，在几年的运行中, 性能不断得到改进, 14C和3H的测量丰度灵敏度分别达到(3.14 ± 0.05)×10−15和(1.23 ± 0.17)×10−16，并在多个学科领域中开展了应用研究。本工作简要介绍其性能特点、运行情况和应用概况，为AMS的小型化和国内产业化提供实验数据，同时为低能AMS在核物理，地球科学，环境科学和生命科学的应用提供技术手段。

     

    Abstract: The Accelerator Mass Spectrometry System of Guangxi Normal University(GXNU-AMS) was successfully installed and operated in 2017. It is the first homemade single-stage AMS system facility and one of the lowest-energy AMS systems in China. The system adopts 150 kV terminal voltage, helium stripping, and +1 charge state in measurements. During several years of operation, its performance has been improved continuously. The measured abundance sensitivity of 14C and 3H has reached (3.14±0.05)×10−15 and (1.23±0.17)×10−16, respectively, and the application research has been carried out in multidisciplinary field. The performance characteristics, operation, and application of AMS are briefly introduced to provide experimental data for the miniaturization and industrialization of AMS in China and to provide technical tools for the application research of low-energy AMS in nuclear physics, geological science, environmental science, and biomedicine.
