摘要

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。

Abstract

The construction of a large area scintillator fiber ion detector array was described. Time resolution of the detector is experimentally determined by two different methods. The best time resolution of the fiber we have got is 520 ps (FWHM). The angle resolution of the scintillator fiber detector array is 0.39° (?φ)

0.79° (?θ). The transmission efficiency of photo-transmitter was also determined by experiment.
