摘要:

本文介绍了一种脉冲形状分析算法和一种在寻找Kr-78的2K俘获实验中抑制大型铜正比计数器信号中噪声成分的方法。这些信号对应于具有不同数量的电荷团簇的复合事件,这是由于由这些信号形成初级电离。提出了一种用于分离单点和多点事件并确定单个簇中的电荷的技术。在多分辨率信号分析中使用Daubechies小波,可以将检测器中多点事件提取的灵敏度和分辨率提高3-4倍。

英文摘要:

A pulse shape analysis algorithm and a method for suppressing the noise component of signals from a large copper proportional counter in the experiment aimed at searching for 2K capture of Kr-78 are described. These signals correspond to a compound event with different numbers of charge clusters due to from primary ionization is formed by these signals. A technique for separating single- and multipoint events and determining the charge in individual clusters is presented. Using the Daubechies wavelets in multiresolutional signal analysis, it is possible to increase the sensitivity and the resolution in extraction of multipoint events in the detector by a factor of 3-4.
