论文摘要
提出的工作证明了创建和研究快速中子来源的数学模型的结果。模型载体是使用Geant4工具包在Linux操作系统环境中使用C ++编程语言开发的计算机程序。所有描述低能模型的必要类用于通过检测器材料模拟中子的通过。这些考虑了弹性散射，非弹性散射，辐射捕获和裂变。本文中列出了包含以两种方式建模的快速中子源的能量光谱的图。对获得的能源谱进行分析。 239Pube中子源创建的模型可用于研究闪烁检测器BI4GE3O12，CDWO4，GD2SIO5等，并研究其特征。可以使用开发的模型来研究快速中子登记期间重氧化物闪烁体物质的过程。结果表明，对于使用BI4GE3O12或CDWO4闪烁体的239Pube中子来源的中子的注册，更可取。虚拟核物理实验的结果满足已发布的实验数据。
The proposed work demonstrates the results of creating and investigating the mathematical model of the source of fast neutrons. The model carrier is a computer program developed in the C++ programming language in the Linux operating system environment, using the Geant4 toolkit. All necessary classes describing low-energy models were used for the simulation of the passage of neutrons through materials of detectors. Those take into account the elastic scattering, inelastic scattering, radiative capture and fission. Diagrams containing energy spectra of a source of fast neutrons modeled in two ways are presented in the paper. The analysis of the obtained energy spectra is carried out. The created model of 239PuBe neutron source can be used for the investigation of scintillation detectors Bi4Ge3O12, CdWO4, Gd2SiO5 and others, as well as studying their characteristics. Processes in heavy oxide scintillators substance during the registration of fast neutrons can be studied using the developed model. It is shown that for registration of the flow of neutrons from 239PuBe neutron source, using Bi4Ge3O12 or CdWO4 scintillators is more preferable. Results of the virtual nuclear physical experiments satisfy the published experimental data.
