摘要
利用TMVA软件包所提供人工神经网络方法进行了多参量的分析,实现对γ射线和强子簇射的分辨.测试结果表明,在对强子簇射的排斥率达到75%的条件下,对γ射线簇射的挑选率可达到80%以上,最高品质因子为2.06.
Multi-variant analysis is performed with TMVA(Toolkit for Multivariate Analysis)program to separate the γ-initiated and hadron-initiated showers.The test shows that the efficiency for selecting the γ-initiated showers can reach more than 80% while rejecting more than 75% of the hadron-initiated showers.The best quality factor is 2.06.
