摘要
在"强光一号"高剂量率脉冲伽马装置上,使用李萨如图形法测量了硅酸镥闪烁体的γ高剂量率脉冲线性响应上限。实验结果表明:硅酸镥闪烁体在脉冲伽马能注量率小于1.9×1019MeV/(cm2.s)时,光输出为线性;大于此限值时,出现非线性响应现象。
The linear response upper limit of lutecium oxyorthosilicate scitillator at high dose rate to pulsed gamma radiation was measured by using Lissajous figure method at the pulsed gamma equipment 'Qiangguang-Ⅰ'. The results of experiment indicate that the light response of LSO is still linear when the pulsed gamma energy flux is below 1.9 × 10^19 MeV/(cm^2 · s), otherwise, non-linear phenomenon appears.
