Same-sided successive-shock HED instability experiments

Inertial confinement fusion (ICF) and high-energy density (HED) physics experiments experience complicated forcing for instability growth mix due to the ubiquitous presence of multiple shocks interacting with perturbations on material interfaces. One common driver is successive from same direction. However, there a severe lack analytic work modeling validation same-sided since they are extremely difficult achieve conventional (non-HED) drivers. Successive access large parameter space; idealized fluid theory [K. O. Mikaelian, Phys. Rev. A 31, 410 (1985)] predicts 15 different interface evolution scenarios sinusoidal perturbation. Growth becomes more complex multi-mode, compressible HED systems. The Mshock campaign first experiment in any regime probe wide portion shock space. This enabled by our development hybrid direct/indirect drive platform capable creating independently controllable National Ignition Facility. These have delivered data rigorously challenging models their ability accurately capture Richtmyer–Meshkov under shocks. Single-mode two-mode successfully demonstrated control various shocked interface, including re-inversion, freeze out, continued growth. Simulations theoretical shown experimental observations linear phase, giving us confidence ICF/HED design codes.
