论文摘要
在本文中，我们处理了预测任意组成和几何形状媒介中稳态中子谱的问题。如果可能的话，这种频谱的分析计算通常太复杂了。我们描述了一种基于GEANT4的蒙特卡洛计算方法的一种方法，该稳态中子光谱中包含固定中子源的培养基中的稳态中子谱。除了稳态光谱外，我们还获得了时间频谱进化的快照，这可能被认为是非平衡的中子光谱，它们的形式对于进一步的研究引起了极大的兴趣。
In this paper we deal with the problem of predicting a steady-state neutron spectrum in media of arbitrary composition and geometry. The analytical calculations of such spectrum are often too complex, if at all possible. We describe a method of Geant4-based Monte Carlo calculation of the steady-state neutron spectrum in a medium containing a fixed neutron source. In addition to the steady-state spectrum, we obtain the snapshots of the neutron spectrum evolution in time, which may be thought of as the non-equilibrium neutron spectra, and their form is of considerable interest for further studies.
