摘要: 束流传输系统是中子发生器研制、调试和技改等工作顺利进行的重要依据。为此开展了中子发生器束流传输系统研究工作，阐述了传输系统光学特性和组成。以ns-200中子发生器为代表实例，详尽地分析了传输系统的组成和各光学透镜的特性。根据LEADS软件要求，生成该器束流传输系统数据输入卡，调用软件相应各光学元件计算模块，进行了模拟计算，给出了束流传输包络图。束流传输模拟计算结果与原设计要求基本一致。Abstract: The beam optical transfer is important for neutron generator research, therefore the research of the beam transfer system was conducted and the system optical character and composition were expatiated.As a typical case, the composition and optical characteristics of the transfer system of ns-200 neutron generator were detailedly analyzed. The data input card of this system was derived according to LEADS software requirement. The simulation calculation produces the beam transfer envelope using relevant optical calculation modules of LEADS based on the card. The envelope agrees well with the designed one．
