A new charge reconstruction combination method for multilayer plastic scintillator detectors
Abstract This paper introduces a new charge reconstruction combination method used Bayesian for multilayer detectors to enhance the charge identification capability. The method employs a Landau convoluted Gaussian function to fit charge distributions of each layer, deriving the probability density function (PDF) which serves as a likelihood function. By combining the likelihood function of the same nucleus in different layers, the joint likelihood function is obtained for each nucleus sample. The combined charge of the incident particle is built according to the Bayesian approach. The new method is used to combine the charge reconstruction results of two layers of plastic scintillator detector, and the effectiveness of the method is verified with the beam test and simulation data. By comparing the performance with the traditional direct averaging method, the Bayesian method is significantly better than the traditional method.
