Conception Design of Shielding Collimator System for High Energy Neutron Radiography with Minitype Neutron Source

Institute of Nuclear Physics and Chemistry of China Academy of Engineering Physics, China

摘要: 准直屏蔽系统是中子照相装置的必要设备。本文采用蒙特卡洛中子输运程序(MCNP)等软件对高能中子准直屏蔽系统进行理论设计,初步确定了其材料构成和外观尺寸,从理论上确定了装置包括成像处注量率、成像距离及相应视场等关键参数。
