  The Rayleigh-Taylor (RT) instability affects a vast range of High Energy
Density (HED) length scales, spanning from supernova explosions (10$^{13}$ m)
to inertial confinement fusion (10$^{-6}$ m). In inertial confinement fusion,
the RT instability is known to induce mixing or turbulent transition, which in
turn cools the hot spot and hinders ignition. The fine-scale features of the RT
instability, which are difficult to image in HED physics, may help determine if
the system is mixing or is transitioning to turbulence. Earlier diagnostics
lacked the spatial and temporal resolution necessary to diagnose the dynamics
that occur along the RT structure. A recently developed diagnostic, the Crystal
Backlighter Imager (CBI), \cite{Hall:2019, DoZonePlate} can now produce an
x-ray radiograph capable of resolving the fine-scale features expected in these
RT unstable systems. This paper describes an experimental design that adapts a
well-characterized National Ignition Facility (NIF) platform to accommodate the
CBI diagnostic. Simulations and synthetic radiographs highlight the resolution
capabilities of the CBI in comparison to previous diagnostics. The improved
resolution of the system can provide new observations to study the RT
instability's involvement in mixing and the transition to turbulence in the HED
regime.
