摘　　要：“神龙一号”加速器是一台20MeV直线感应电子加速器.本文介绍了“神龙一号”的物理设计、研制过程和调试结果.物理设计中主要分析了加速器研制的技术难点,并给出各分系统应达到的技术要求和具体结果.文中重点介绍了脉冲功率系统、注入器、束流的调试情况,调试结果表明,“神龙一号”加速器输出电子束的参数为:电子能量20MeV、束流强度2.5kA、束流脉冲宽度～70ns、能散度0.64%、发射度2060mm·mrad、打靶焦斑尺寸1.2mm.Dragon-Ⅰ is a linear induction electron accelerator. This facility consists of a 3.6MeV injector, 38 meter beam transport line and 16MeV induction accelerator powered by high voltage generators, including 8 Marx generators and 48 Blumlein lines. This paper describes the physics design, development and experimental results of Dragon-Ⅰ. The key technology is analyzed in the accelerator development, and the design requirements and operation of the major subsystems are presented. The experimental results show Dragon-Ⅰ generates an 18—20MeV, 2.5kA, 70ns electron beam. The X-ray spot size is about 1.2mm and dose level about 0.103 C/kg at 1 meter.
