摘要

提高14C的测试精度和10Be、26Al等长寿命放射性核素的丰度灵敏度是加速器质谱（AMS）领域的热点问题之一。西安加速器质谱中心设计了一套基于HVEE公司4130型加速器质谱计的双用注入系统。通过速度分析器的作用

在一套系统上实现交替注入和同时注入两种工作模式

较大程度上简化了以往两套系统共存的布局。计算结果表明

此系统既可以进行10Be、26Al的超高灵敏度测量

又继承了4130型AMS高精度的14C测试能力

拓展了其测量核素的范围。

Abstract

It is well demanded to improve the precision of 14C dating and the sensitivity of long lived radioisotopes such as 10Be and 26Al in the AMS field. A set of new dual-purpose injection system based on HVEE model 4130 AMS facility is proposed by Xi’an AMS Center

which can operate in both simultaneous and sequential modes on one set of the system by using the Wien filter. It obviously simplifies the layout as compared with the existing dual-injector and dual high energy beam line system. The calculation shows that the new dual injection system will increase the species of radionuclides which can be analyzed. Keeping the high precision of model 4130 AMS for radiocarbon dating the new system can achieve the ultra-sensitivity measurements for the nuclides such as 10Be and 26Al.
