串列加速器质谱计束流传输系统的设计特点

THE DESIGN OF SOME BEAM TRANSPORT ELEMENTS FOR TANDEM AMS

  • 摘要: 串列加速器用于测定~(10)Be为例,阐述质谱计(AMS)束流传输系统的设计特点。实现了对高丰度稳定同位素强峰拖尾的有效抑制和束流“平顶传输”,以及确定分析缝宽和解决加速电压的稳定。得到注入系统分析磁铁的质量分辩率R_(10)~(-5)为66,高能分析磁铁的质量分辨率R_(10)~(?11)≥176。

     

    Abstract: Taking measurement of ~(10)Be as an example, the main design features of beam transport system ofSINR tandem AMS are presented.
