Dragon-I Linear Induction Electron Accelerator

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.
