Plasma kinetic effects on interfacial mix in settings relevant to inertial confinement fusion and laboratory experiments
POSTER
Abstract
Mixing of high-Z/low-Z interfaces in dense plasma media is a problem of importance for understanding mix in inertial confinement fusion experiments and recent experiments at the LANL Trident facility. In this presentation, we apply the VPIC particle-in-cell code [1] with a binary collision model [2] to explore kinetic effects of the atomic mixing. Comparisons are made to published analytic theory and hybrid modeling results [3] and conditions are identified under which plasma kinetic behavior may lead to anomalously rapid atomic mixing. \\[4pt] [1] Bowers et al., \textit{Phys.
