Z箍缩和闪光照相在惯性约束聚变(ICF)、核辐射效应和高性能爆轰流体动力学等研究中具有重要应用,Z箍缩ICF和多脉冲多角度高能脉冲X射线闪光照相对脉冲功率源提出了巨大挑战,国际上正在积极发展和探索可实现直接驱动Z箍缩和闪光照相二极管的快脉冲功率源新技术。综述了国际上近年来快Marx发生器(FMG)和快直线型变压器(FLTD)等脉冲功率源方面的发展动态,初步分析了两种技术途径的优缺点和制约性因素,以及需要开展的关键技术,介绍了西北核技术研究所的相关研究进展,最后提出了几点看法和建议。
Z-pinch and flash X-ray radiography have an important application in inertial confine fusion (ICF)and nuclear radiation effects simulation and high performance hydrodynamic test, etc. Z-pinch ICF and multi-pulse multi-axis high energy X-ray radiography put forward a huge challenge for pulsed power driver, so the direct-driven-load fast pulsed power driver are developed actively in home and ahroard. The paper summarized the recent advances and developing trends of the fast pulsed power driver based on fast Marx(FMG) and fast linear transformer driver(LTD), and analysized the advantages and disadvantages and restricting factors about FMG and FLTD and their key technologies, then introduced the state-of-arts on the investigation in Northwest Institute of Nuclear Technology. In the end, the paper presented some advices and views about studying fast pulsed power driver applied to Z-pinch and flash X-ray radiography in home.
