标题： Advantages of off-line analysis of digitally recorded pulses in case of neutron-gamma discrimination in scintillators

摘要： 许多现代数字分析仪提供从电离辐射探测器记录原始脉冲的能力。 我们利用这一机会，研究电荷比较法在有机玻璃闪烁体和反式联苯测量的中子和伽马辐射脉冲形状鉴别中的有效性。 简要描述了用于数字化记录数据自动离线分析的软件想法。 我们讨论了前沿触发和恒定分数触发方法之间的差异，并提出以脉冲最大值作为替代触发方式。 我们观察到电荷积分门的起始点对优值有重大影响，因此需要仔细选择它，并与其他电荷比较法参数一起报告，以保持闪烁体之间的比较可靠。 优值的使用有限，因此提出了最小相对高度作为实际应用中中子-伽马鉴别效果的附加指标。 显示英文摘要

摘要： Many modern digital analyzers offer the ability to record raw pulses from ionizing radiation detectors. We use this opportunity to investigate the effectiveness of Charge Comparison Method in Pulse Shape Discrimination of neutron and gamma radiation measured with organic glass scintillator and trans-stilbene. The idea of software for automated off-line analysis of digitally recorded data is briefly described. We discuss the difference between Leading Edge and Constant Fraction Discrimination triggering methods and we propose triggering on pulse maximum as an alternative. We observe that the starting point of charge integration gates has major impact on Figure of Merit values, therefore it is important to choose it carefully and report it with other Charge Comparison Method parameters to keep comparison between scintillators reliable. Figure of Merit has a limited usage, so Relative Height of Minimum is proposed as an additional indicator of neutron-gamma discrimination effectiveness in practical applications.
