The pulsed neutron experiment (the variable geometric buckling experiment) in spherical geometry has been simulated using the MCNP code. The time decay of the thermal neutron flux has been observed as a function of the sample size. The thermal neutron diffusion cooling coefficient C with the correction F has been determined for three basic rock minerals (quartz, calcite, dolomite) at the given specific densities. The corresponding density-removed parameters have also been obtained.
已使用MCNP代码对球形几何结构中的脉冲中子实验(可变几何曲率实验)进行了模拟。已观察到热中子通量的时间衰减与样品尺寸的函数关系。已针对给定特定密度下的三种基本岩石矿物(石英、方解石、白云石)确定了带有修正因子F的热中子扩散冷却系数C。还获得了相应的密度去除参数。
