摘要

本文报道了16兆电子伏特电子辐照产生的有机蓝绿闪烁纤维的闪烁光产率下降的原位观测和时间压缩老化和恢复研究的新实验结果。只有在低电流密度下，观察到的原位退化才有接近线性的下降。典型的自退火效应可以用对数定律来表征。当能量剂量分别高于10mrad和20mrad时，蓝色闪烁体和绿色闪烁体的光学性质不会完全恢复。

On radiation damage of scintillating organic fibres in dependence on energetic electron bombardment

New experimental results on in-situ observations of degradation of scintillating light yield and on time-compressed ageing and recovery studies of organic blue and green scintillating fibres generated by 16 MeV electron irradiation are reported. Only for low current densities the observed in-situ degradation has a nearly linear decrease. Typical self annealing effects can be characterized by a logarithmic law. Total recovery of optical properties for blue and green scintillators does not occur for energy doses above 10 Mrad and 20 Mrad, respectively.
