高纯锗(high-purity germanium, HPGe)探测器是γ放射性分析的重要设备之一。HPGe探测器实验对于核学科人才培养至关重要。基于兰州大学核科学与技术学院HPGe探测器本科生实验教学需求,开发了基于LabVIEW的可视化数据分析系统。系统以可视化的编程方式完成HPGe探测器的效率刻度和能量刻度,能够实现对实验数据的分析与处理及实验结果的可视化输出,具有活度测量和未知源判断两种功能。系统界面清晰简洁、操作方便,丰富了实验教学模式,有助于激发学生的学习兴趣,提升实验课堂教学效果。同时,该系统在中子活化分析、核素分析、环境辐射监测等方面也具有一定的应用价值。 相似文献

The D(d,p)T reaction in Be metal environments has been measured to investigate the electron screening effect in metals in an energy region of from 5.5 keV to 10 keV in a center of mass system (CMS) at a temperature of 121 K. The depth distribution of deuteron density in Be metals has an impact on the observed reaction yields. A model of deuteron density distribution in metal has been proposed to obtain the original yields. A screening energy of (116±46) eV has been obtained with the assumed deuteron density distribution model. 相似文献
