On the Omega laser facility we have symmetry experiments with 3 cones of beams in order to mimic the LMJ configuration. Hydro-instabilities have been studied in CHGe planar samples with face-on and side-on radiographies. We improved our neutron image system on the Omega. A LMJ preliminary domain corresponding to the possible operation at 2$\omega $ has been determined. For our nominal target at 3$\omega $ we studied the low mode instability effects on the DT deformation and on the yield. Finally the stability is clearly improved for our nominal capsule L1215 with CH doped with graded Ge.
