Metal nano-particles modernized layers and those with polymers for laser thermonuclear targets

Abstract

The manufacturing and precision monitoring methods of the layers as promising direct and indirect targets for Inertial confinement fusion (ICF) are under study, as well as their application in the experiments. The metal-containing foams with a density that is several times or several orders of magnitude smaller than the full-density material of the same composition are of interest for higher laser light conversion into X-rays and for better energy delivery into the target in direct and indirect interaction schemes. Such targets are developed and provided. We report the interaction of Nd: glass laser with a low-density bismuth and gold targets. The plasma dynamics and X-ray emissions were observed using multiframe optical shadowgraphy and an X-ray streak camera. Enhanced X-ray intensities and festoon plasma flame are observed from the metal low-density layers.
