摘要
基于射线与物质的相互作用原理和辐射输运理论,建立了近地空间强流脉冲中子源在大气中输运时与气体散射产生γ射线传输到同步轨道的数学物理模型,应用MCNP程序对散射γ输运至地球同步轨道的特征参数进行了数值模拟,获得了一些规律性的辐射现象,并依据这些辐射特征,初步提出了散射γ探测器相关指标,为相关研究提供了一定参考。
Based on the radiation transportation theory and the interaction principle between particle and material,it has built a mathematical and physical model of inelastic scattering gamma-ray by near-earth space high intensity neutron source transportation to the geosynehronous orbit. MCNP has been applied to simulate the characteristics parameters of inelastic scattering gamma-ray transportation to the geosyn-chronous orbit numerically. It has got some rule radiation phenomena. According to the radiation characteristics it brings forward the guide lines of the pulsed gamma-ray detector assumably. This thesis prorides positive reference for some relative research.
