摘要:

波长偏移光纤广泛用于从闪烁计数器收集光,这允许将各种闪烁平面连接到光电检测器的相对小的光电阴极,特别是硅光电倍增器的微小光电阴极。2020年10月,可乐丽宣布生产一种新的快速纤维。我们对新纤维YS-2和成熟的Y-11进行了比较。光纤YS-2的衰减时间比Y-11的衰减时间短近两倍:$\approx$为4.0 ns,而$\approx$为7.4 ns。同时,它的光输出和衰减长度与Y-11一样好,这使得YS-2成为定时闪烁探测器的良好选择。

英文摘要:

Wavelength shifting fibers are widely used for light collection from scintillation counters, which allow connection of various scintillation planes to relatively small photocathodes of photodetectors and especially tiny photocathodes of silicon photo-multipliers. In October 2020 Kuraray announced production of a new branch of faster fibers. We performed a comparison of the new fiber YS-2 to a mature Y-11. The fiber YS-2 demonstrated decay time nearly two times shorter than that of Y-11: $\approx$4.0 ns versus $\approx$7.4 ns. At the same time its light yield and attenuation length are as good as of Y-11, which makes YS-2 a good choice for timing scintillation detectors.
