针对中微子探测的多变量分析本底抑制方法
Multivariate analysis background suppression methods for neutrino detection
摘要
Abstract
To improve the background suppression effect of neutrino detection and solve the problem of low event re-construction efficiency in neutrino detectors,this paper proposes a small array neutrino detector scheme composed of multiple plastic scintillator units coupled with silicon photomultiplier readout.The suppression effect of the multi-variate analysis method on the background in neutrino detection was studied using the multivariate analysis method of array detectors by designing and manufacturing small array detectors.A 3×3 small array detector was built,and the pulse shape discrimination capability of the detector and the different topological structures of neutrons and gam-mas were tested.Combined with Monte Carlo simulation-based analysis,the effectiveness of the array detector's multivariate analysis method for background suppression was analyzed.The results show that the simulation and ex-perimental results are consistent,and the multivariate analysis method can effectively suppress background noise.关键词
