摘要
对大面积光纤阵列探测器中的光纤阵列探测单元的性能进行检测。测试了不同形状、不同材料的光导以及光导包裹不同反光材料时光纤探测单元的传输效率及时间分辨和位置分辨。确定了大面积光纤探测器探测单元所使用光导的材料和形状,给出了光纤阵列探测器探测单元可达到的时间分辨。
The structure of the large area scintillating fiber array (LASFA) detector and the characteristics of the scintillating fibers unit were described. The transmit efficiency and the effects on the time and spatial resolutions were measured in different conditions by using the different light guides with different shapes, materials and covering materials. In conclusion, the time and spatial resolutions were given and the best condition was determined for the light guide used in the LASFA detector.
