Development of fast pulsed power driver for radiography and Z-pinch
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 abroard.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.
