Abstract

We developed a monochromatic crystal backlight imaging system for the double-cone ignition(DCI)scheme,employ-ing a spherically bent quartz crystal.This system was used to measure the spatial distribution and temporal evolution of the head-on colliding plasma from the two compressing cones in the DCI experiments.The influence of laser parameters on the x-ray backlighter intensity and spatial resolution of the imaging system was investigated.The imaging system had a spatial resolution of 10 μm when employing a CCD detector.Experiments demonstrated that the system can obtain time-resolved radiographic images with high quality,enabling the precise measurement of the shape,size,and density distribution of the plasma.

Key words

double-cone ignition(DCI)/spatial resolution/x-ray radiography
