| 中文摘要: |
| 针对基于LED的LaBr3:Ce3+闪烁γ谱仪稳谱技术进行研究,介绍了稳谱原理,搭建了硬件测量系统,利用计算机编程控制,通过标定保持待测能区不变时参考峰位随温度变化曲线,达到了非线性稳谱目的,实测稳谱效果在温度0~50 ℃变化时偏离不超过±1道. |
| 英文摘要: |
| In this paper,the spectrum-stabilizing technique research of LaBr3:Ce3+ scintillation gamma spectrometer based on LED is presented.It introduces the principle of stabilizer and sets up the hardware measuring system using computer programming control.It is demarcated that the curve of reference peak position changed with the temperature when ROI remained at constant,to achieve the nonlinear stabilizer.The measured stabilizer effect deviates not more than ±1 channal when the temperature is 0 to 50 ℃. |
