    Abstract
  • Methods and experiments of applying VISAR to measure particle velocity history at the interface between shocked Cu specimen and LiF window and LiF specimen and LiF window are described, respectively. The peak stress levels were 6.5 GPa and 3.61 GPa. Wedged LiF window was applied to smooth out the effect of the reflected light and parasitical interference from the window rear surface, and as a result the signal-to-noise ratio and the reliability of window VISAR were improved significantly.
