本文描述了兰州放射性束流线(RIBLL)终端大面积闪烁光纤矩阵探测装置的结构。用两种方法测量了该光纤矩阵单元的时间分辨,得到的最佳时间分辨为520ps(FWHM)。光纤矩阵探测装置的角分辨为?φ≈0.39°,?θ≈0.79°。同时,实验研究了探测器所用光导的传输效率和对时间分辨的影响。
This article describes the structure of Lanzhou radioactive beam line (RIBLL) terminal large area scintillation fiber matrix detection device. The time resolution of the optical fiber matrix unit was measured by two methods, and the best time resolution was 520ps (FWHM). The angular resolution of the optical fiber matrix detection device is? Φ≈0.39 ° and? Θ≈0.79 °. At the same time, the experimental study of the light transmission efficiency of the detector and the impact on time resolution.
