ONE-DIMENSIONAL AND 2-DIMENSIONAL FAST X-RAY-IMAGING OF LASER-DRIVEN-IMPLOSION DYNAMICS WITH X-RAY STREAK CAMERAS

One- (1D) and two-dimensional (2D) x-ray imaging techniques with x-ray streak cameras have been developed and utilized for investigating imp losion dynamics of laser fusion targets. Conventional streaked 1D imag es of the shell motion of the imploding target was recorded together w ith the time-resolved 2D multi-imaging x-ray streak images of the core shapes on the same x-ray streak camera. Precise comparison of the cor e dynamics between the experimental and simulation results was perform ed with an accuracy of 30 ps by fitting the trajectories of the x-ray emission from the imploding shell.
