论文摘要
在MUON散射断层扫描中，根据给定能量值以原子数，密度和培养基的厚度，根据原子数，密度和厚度的散射角度进行区分。不同初始能量的散射角度还为将传入的兆子分类为多个能量群提供了机会。在这项研究中，通过采用GEANT4代码，我们表明，偏转角指数呈指数为能量的函数，并且当前配置的数值低于检测器的精度，除了初始能量箱，除了低Z，低密度，低密度和当前塑料闪烁体的低厚度。这意味着需要其他组件会引起兆子散射。因此，我们将不锈钢表面引入顶部和底部部分，以扩大偏转角以及降低不确定性，从而改善检测器的性能。
In muon scattering tomography, the investigated materials are discriminated according to the scattering angle that mainly depends on the atomic number, the density, and the thickness of the medium at a given energy value. The scattering angles at different initial energies also provide the opportunity to classify the incoming muons into a number of energy groups. In this study, by employing the GEANT4 code, we show that the deflection angle exponentially decays as a function of energy, and the numerical values for the current configuration are below the detector accuracy except the initial energy bins owing to the low-Z, low density, and low thickness of the current plastic scintillators. This implies the necessity of additional components that provoke the muon scattering. Therefore, we introduce stainless steel surfaces into the top and bottom sections in order to amplify the deflection angle as well as to reduce the uncertainty, thereby improving the detector performance.
