Experimental Characterization of HED Feature-Driven Jets at Omega EP

High-energy-density (HED) systems, such as inertial confinement fusion (ICF), are susceptible to hydrodynamic instabilities that can significantly affect both experimental results and modeling predictions. These instabilities can induce mixing across material interfaces, which is a primary contributor to degrading ICF performance. Particularly, instability-driven jetting from interacting features (such as divots) can be especially destructive at interior layers. Determining the range of conditions where this occurs as well as our ability to mitigate this effect both require extensive experimental investigation and benchmarking of 2- and 3-D simulations. This talk will detail an experimental platform fielded by Los Alamos National Laboratory at the Omega EP Laser to characterize the effect of feature-driven jetting in HED systems as a part of a larger multi-facility, multi-scale investigative effort.
