Fig. 2: Experimental radiographs of the mono-mode targets.

Experimental radiographs of mono-mode targets obtained before (40 ns (a) and (c)) and after (60 ns (b) and (d)) the transition to turbulence between 50 and 60 ns. Following the initial Rayleigh–Taylor growth and pusher expansion (curved modulated surface of the two first radiograph), the system becomes turbulent. The structure becomes blurry and the power spectrum nearly isotropic, as can be observed on the zoom of the 60 ns radiograph. A precise study was made possible thanks to the high resolution of the radiography, which is illustrated on the zoom and line-out of the 40 ns radiograph (c).
