| 摘 要： | 针对系统电磁脉冲效应研究需求,项目组对"闪光二号"加速器进行了适应性改造,以便于产生脉冲硬X射线。主要采用二次成形的水线结构,重点进行了水开关设计,并完成了实验调试。装置输出电压650kV^1.3 MV稳定可调,脉冲宽度60ns,前沿由改造前的80ns缩短至改造后的30ns,在国内首次成功驱动串级二极管,产生前沿29ns、射线宽度约53ns的脉冲硬X射线。

| Abstract: | For the requirements of SGEMP research, the Flash-Ⅱ accelerator has been transformed to improve the simulation capability of pulsed hard X rays. A two-stage waterline together with its water switches was adopted to upgrade the driver. The experimental results show that the designed performance has been achieved. With a much shorter risetime of 30 ns, the transformed accelerator now can reliably output a 60 ns width voltage from 650 kV to 1.3 MV. Using the accelerator, a diode with two stages in series has been developed and 53 ns pulse X-rays with risetime of 29 ns have been obtained successfully. |
