Instabilities and radiation flow at a hot plasma interface
POSTER
Abstract
Mixing and radiation flow have a complex relationship in laser-driven hohlraums, an environment in which the formation and evolution of hydrodynamic instabilities may not be well suited to analysis using mix models calibrated for low temperature materials. The Hohlraum Wall Heating campaign at the National Ignition Facility aims to quantify the influence of radiation on mix (and vice-versa) at a high-Z/low-Z interface through simultaneous radiation burn-through measurements and high-resolution x-ray radiography. We discuss the qualification of the platform and data from our initial shots compared to 3D radiation hydrodynamic simulations and present options for future development.
