Single-mode experiments have successfully demonstrated the ability to access and control the various growth states of the shocked interface, including re-inversion, freeze-out, and continued growth. Data is shown to agree between experiment, theory, and simulation in the linear growth phase, giving us confidence in our ICF/HED design codes. Multi-mode experiments demonstrate distinct growth scenarios for the different modes and form a first basis of tests for initialization parameters of non-linear instability and turbulence models [Braun and Gore, Physica D, 404 (2020)] in this regime.
