Abstract

In indirect drive configuration, the Laser MegaJoules 60 quads induce an azimuthal asymmetry of the hohlraum lighting, which can be reduced using an elliptical focal spot. This paper deals with the characterization of the spot size according to both the azimuthal symmetry and the passing-through Laser Entrance Hole criteria. We have investigated the acceptable domain of laser spot sizes for various possible LMJ configurations. The, we have quantified the azimuthal asymmetry decrease due to the elliptical spot elongation.
