Popis: The temperature measurement of preheated target is reported. Inertial confinement fusion (ICF) targets should be imploded with a low adiabat for achievement of high density compression. The high energy photons and electrons from ablation plasma can preheat the uncompressed fuel and disturb the low adiabat compression. Preheat has to be evaluated and suppressed for ICF targets. The planar target of cryogenic deuterium was developed for measurement of the self emission from the rear surface. Experiment indicated that the x-ray preheating is more effective than that of non-local electron heat transport at the laser intensity of 1014 W/cm2.
