Germanium-doped CH (CHGe) is one nominal ablator for LMJ target design. To investigate its properties we performed indirect drive planar Rayleigh-Taylor experiments on the OMEGA laser facility . On each shot foil motion and modulations growth were simultaneously measured by side-on and face-on radiography, while drive was assessed by measuring radiation escaping through the hohlraum laser-entrance-hole (LEH). This complete set of data allows a more stringent comparison between the hydrocode simulations and the experimental results. We compare CHGe perturbations growth with those acquired on CHBr in the same experimental configuration. These preliminary results are the first step toward a test-bed validation of CH(Ge) as an ablator on OMEGA and further on LiL .
