AI 中文摘要
我们报道了Luxium Solutions公司生产的BCF-20XL闪烁波长位移（Sci-WLS）光纤的光学特性与电离辐射测量结果。采用3.0米长的该光纤和分光光度计，通过透射发射光谱得到衰减长度，并用双组分衰减模型描述，得到长衰减长度为6.70米，短衰减长度为0.16米。光谱测量进一步显示，长衰减组分随波长增加而增大，而短衰减组分在更长波长下变得不显著。还采用基于硅光电倍增管（SiPM）的读出装置，在放射性α、β和γ辐照下对闪烁响应进行了表征，提供了BCF-20XL光输出的基准测量值。
英文摘要
We report optical characterization and ionizing-radiation measurements of the scintillating-wavelength-shifting (Sci-WLS) fiber BCF-20XL from Luxium Solutions. Attenuation lengths were obtained from transmitted emission spectra using a 3.0 m fiber with a spectrophotometer and described with a two-component attenuation model, yielding a long attenuation length of 6.70 m and a short attenuation length of 0.16 m. The spectral measurements also reveal wavelength-dependent attenuation, with the long component increasing with wavelength and the short component becoming less significant at longer wavelengths. The scintillation response was also characterized under radioactive alpha, beta, and gamma irradiation using SiPM-based readout, providing a benchmark measurement of the light output from BCF-20XL.
