Pulsed power research at the institute of fluid physics

  • 摘要: 中国工程物理研究院流体物理研究所是中国最早开展高功率脉冲技术研究的单位,文章简要回顾了流体物理研究所50年来在高功率脉冲技术研究方面的研究情况,介绍了中国大型高功率装置的典型代表、新近建成的世界最高水平的直线感应加速器神龙一号装置(20MeV, 2.5kA, 80ns),以及超高功率装置——正在建设的用于Z箍缩研究的初级实验平台(PTS, 8—10MA, 90ns).神龙一号是由84个感应腔串接而成的强流脉冲直线感应电子加速器,每个感应腔由Marx高电压发生器和Blumlein脉冲形成线组成的高功率脉冲系

     

    Abstract: The Institute of Fluid Physics was the earliest institution in China to engage in pulsed power research, covering areas such as the development of high power switches, linear induction accelerators, facilities for Z-pinch studies, pulsed X-ray machines, explosive magnetic compression technology, rep-rate pulsed power generation, time resolved diagnostic technology, and so on. The newly built Dragon-I facility (20 MeV, 2.5kA, 80 ns), curently the most advanced linear induction accelerator in the world, is described. The status of the Primary Test Stand (PTS, 8—10 MA, 130ns) for Z-pinch studies that is still under construction is also reported. The PTS consists of 24 modules based on the Marx generator-water PFL (pulse forming line) technology. The single module prototype has been tested successfully. Other progress on the rep-rate pulsed power generator, linear transfer driver, and time resolved diagnostic technology is also presented.
