摘要

利用蒙卡程序DCM/CEM和LAHET对加速器驱动的次临界系统ADS标准散裂中子靶进行了计算。长为0.6m、直径为0.2m的圆柱形Pb靶在0.15—1.6GeV的高能质子轰击的情况下

利用两软件对质子在靶208内的能量沉积、Pb靶发生散裂反应产生的中子及靶内和表面的中子注量、中子能谱分布等进行了比较计算。结果表明:两者模拟结果在中能区（0.8—1.0GeV）符合很好

但在质子能量较高或较低时

两者略有差别。

Abstract

The standard spallation target of ADS (Accelerator-Driven System) was theoretically calculated with Monte Carlo codes of DCM/CEM and LAHET in the present work. The spallation target (0.6 m long and 0.2 m in diameter) bombarded with 0.15—1.6 GeV energetic proton beam was simulated. The proton energy deposition in tar- get

neutron yield

neutron fluence distribution on the outer surface of target and the neutron spectrum distribution were simulated with the two codes. It is shown that

in the proton energy range of 0.8—1.0 GeV

both calculated re- sults agree to each other; but when the proton energy falls outside this energy range

there are some differences be- tween the results with both codes.
