中子半影成像的闪烁体阵列空间分辨力模拟
Simulation on spatial resolution of scintillator arrays based on neutron penumbral imaging system
摘要
Abstract
In order to compare three kinds of scintillation detectors,the Monte Carlo method is introduced to calculate the spatial resolution and energy deposition of scintillator arrays with different fiber diameters. According to simulation results, the resolution of standard liquid scintillator array is better than that of plastic scintillator array, and the resolution of deuterated liquid scintillator array is almost half that of standard liquid scintillator array. The energy deposition of hydrogen-rich scintillator is higher than that of deuterated scintillator. Moreover, smaller fiber diameter leads to better spatial resolution, and thicker scintillator leads to higher energy deposition.关键词
