Abstract :
In this paper, we present recent analysis that allowed us to explain the full history of the temperature pulse shape and highlights the importance of the interaction between the axial plasma jet and the hohlraum wall in expansion, which artificially increases the temperature seen by diagnostics. Experimental/numerical results confrontation will be shown. Conclusion on this kind of vaccum hohlraum configuration is given.
