摘要
基于探测器能量收集特性及探测器输出脉冲的时间-幅度变化关系,研究提出用二项高斯公式拟合其变化曲线,根据拟合的6个参数判别脉冲是否堆积及其堆积形式。通过实际采集的脉冲信号验证了该方法的正确性。
Based on energy collecting characteristics of detector and variation relation of time-amplitude, a Gauss fit curve with six fitting parameters was presented in order to distinguish pulse pile-up and pile-up format. The correctness of the method was verified with real pulses.
