Problems of measurement of dense plasma heating in laser shock-wave compression
Experimental results of heating measurements of
matter carried out in a study of laser-driven shock waves
in aluminum (Batani et al. 1997) are discussed.
The measured temporal evolution of the "color"
temperature of the rear surface of the target is compared
with that computed by a numerical code. It has been established
that the target preheating can substantially affect optical
signal features recorded from the rear side of the target,
and consequently influence upon the accuracy of temperature
and pressure measurements of the material behind the shock
wave front
