摘要 运用蒙卡程序MCNPX对加速器驱动次临界反应堆系统(简称ADS)的标准散裂中子靶进行了计算研究.计算了在0.6~1.5 GeV的质子轰击下,标准Pb靶发生散裂反应产生的中子产额及分布、中子能谱以及靶内能量沉积分布.计算结果与文献理论数据、实验数据进行了比较. The spallation target of Accelerator-Driven sub-critical System (ADS) is studied using the program MCNPX. The calculation of standard lead target bombarded with 0.6 - 1.5 GeV proton beams is carried out. The neutron spectra and distribution over the lead target, energy deposition and neutron production in the lead target are studied. The simulation results agree with the former theoretical and experimental results.
