Abstract

We measure the decay time and the attenuation length of newly developed wavelength-shifting fibers, YS series from Kuraray, which have fast response. Using a 405 nm laser, the decay times of the YS-2, 4, and 6 are measured to be 3.64 ± 0.04 ns, 2.15 ± 0.03 ns, and 1.47 ± 0.02 ns, respectively, for the light injection distance of 10 cm. The decay time of Y-11 is measured to be 7.10 ± 0.09 ns using the same system. All fibers are found to have similar attenuation lengths of more than 4 meters. When combined with the plastic scintillators EJ-200 and EJ-204, the YS series have better time resolution than Y-11, with light yields of 60–100% of Y-11.

具有短衰减时间的新型可乐丽波长变换光纤的性能

我们测量了可乐丽公司新开发的具有快速响应能力的 YS 系列波长转换光纤的衰减时间和衰减长度。使用 405 nm 激光，在光注入距离为 10 cm 时，测得 YS-2、4 和 6 的衰减时间分别为 3.64 ± 0.04 ns、2.15 ± 0.03 ns 和 1.47 ± 0.02 ns。使用同一系统测得 Y-11 的衰减时间为 7.10 ± 0.09 ns。所有光纤的衰减长度相似，均超过 4 米。当与塑料闪烁体 EJ-200 和 EJ-204 结合使用时，YS 系列的时间分辨率比 Y-11 更高，光产率为 Y-11 的 60-100%。

期刊介绍： Progress of Theoretical and Experimental Physics (PTEP) is an international journal that publishes articles on theoretical and experimental physics. PTEP is a fully open access, online-only journal published by the Physical Society of Japan. PTEP is the successor to Progress of Theoretical Physics (PTP), which terminated in December 2012 and merged into PTEP in January 2013. PTP was founded in 1946 by Hideki Yukawa, the first Japanese Nobel Laureate. PTEP, the successor journal to PTP, has a broader scope than that of PTP covering both theoretical and experimental physics. PTEP mainly covers areas including particles and fields, nuclear physics, astrophysics and cosmology, beam physics and instrumentation, and general and mathematical physics.
