摘要

为在专用于14C分析的上海超灵敏小型回旋加速器质谱计（SMCAMS）上尝试分析26Al

计算了加速轨道

确定了高频频率、加速圈数、倍频数等参数

还对注入系统做束流光学计算。做了分析26Al的初步实验

得到了频谱曲线

测量到1.15×10-9A的27Al-束流以及0.038CPS分析26Al的本底

并计算出SMCAMS分析26Al的丰度灵敏度。

Abstract

Shanghai Mini-Cyclotron based Accelerator Mass Spectrometer(SMCAMS) was especially designed for analyzing 14C. In order to accelerate and analyze 26Al the accelerated orbit and beam optics in injection system were calculated and harmonic number and acceleration turns was optimized. Preliminary experiment was carried out. In which a beam current of 1.15×10-9A for 27Al-and 0.038 CPS background for 26Al were measured. The limited sensitivity of 26Al/27Al is 5.25×10-12.
