摘　　要：概述激光驱动束靶相互作用产生中子的蒙特卡罗程序MCNRC的程序设计和进展。详细阐述MCNRC中的离子输运过程和中子产生过程中应用的物理模型和数据库,并展示MCNRC的模拟计算和实验数据或与其他模拟数据之间的比较。介绍该程序应用于质子锂反应、氘锂反应和锂质子反应,三种基于不同核反应中子源的模拟计算,计算结果表明,MCNRC对上述中子源具有较好的模拟能力。The programming and development of the Monte Carlo code MCNRC for neutron calculation driven by intense laser with pitcher-catcher scheme are described in this study.We describe the physical models and databases utilized in the MCNRC’s ion transport and neutron production processes,and we compare simulation results to experimental or other simulated data to demonstrate the validity of MCNRC.The program is applied to three neutron sources that are based on various nuclear reactions,including the proton-lithium reaction,the deuterium-lithium reaction,and the lithium-proton reaction.The results show that MCNRC has preferable simulation capabilities for these neutron sources.
