Turbulent mixing investigations at the ISKRA-4 facility

Results of turbulent mixing research of thin Al and Au layers under laser a cceleration of the three-laser targets Si/Al/Au are presented. Analyses of experimental data under the program SND-TUR, where the Nikiforov model is u sed for turbulent mixing description, testify to the essential impact of ho t spots on the examined processes in distribution of laser radiation intens ity on the surface of the target. Experimental setup on the laser beams' sm oothing by the "foam" coated on the target, has been considered. The result s of the first experiments are presented.
