CsI(Tl)探测阵列的升级及测试

Upgrade and Test of the CsI(Tl) Detection Array

  • 摘要: 在中低能放射性核束物理实验中,硅和CsI(Tl)探测器通常组成Si-CsI(Tl)望远镜,利用 \varDelta E \text- E 方法鉴别带电粒子。CsI(Tl)探测器的光输出大小、光输出均匀度以及配套的获取系统等对其性能和望远镜的粒子鉴别能力有重要影响。本工作尝试从改换CsI(Tl)晶体的包装材料、光电转换设备等方面提高光输出,改善探测器的长期稳定性和楔形探测器的光输出不均匀度;还测试对比了不同获取系统对CsI(Tl)探测器性能的影响,结果表明,最优参数下的数字化获取系统在能量分辨率和获取效率方面优于传统获取系统。

     

    Abstract: In radioactive nuclear beam physical experiments with middle and low incident energies, the CsI(Tl) detectors are usually combined with the silicon detectors to make up of the Si-CsI(Tl) telescopes to identify charged particles using the \varDelta E \text- E method. The performance of CsI(Tl) detector and the particle identification property of Si-CsI(Tl) telescope depend on the light output amount, light-output uniformity, as well as data acquisition system (DAQ). In this paper, we try to change the covering materials and the photon-electron conversion devices of the CsI(Tl) detector to increase the light output, improve the detection long-term stability and the light output uniformity of the wedged CsI(Tl) detector. Moreover, we test and compare the properties of Cs(Tl) detectors using different DAQ systems, which show that the energy resolution and the counting effective are better if the digital DAQ with the best parameters set is used for the Cs(Tl) detector.
