Ejected particle size distributions from shocked Cerium targets

ORAL

Abstract

We report on the results of experiments to constrain the size distributions of particles ejected from shocked Cerium wafer surfaces into vacuum and various pressures of Helium and Deuterium gases by measuring the angular distribution of laser light scattered by the particles. These data are analyzed using the Mie solution to Maxwell's equations and assuming that the particle size distribution function is log normal thereby yielding a continuous record of the size distribution with time, or alternatively with ejected particle velocity, throughout the duration of each experiment..
