High-gain direct-drive target design for the Laser Mégajoule
B. Canaud,X. Fortin,F. Garaude,C. Meyer,F. Philippe,Mauro Temporal,Stefano Atzeni,Angelo Schiavi +7 more
TL;DR: In this article, a CH-foam ablator filled with cryogenic deuterium-tritium is used for direct-drive target design in the context of the French Laser-Mfusion research program, and the hydrodynamic stability of the implosion is investigated at the ablation front and the hot-spot surface.
Journal ArticleDOI
Inertial confinement fusion: Ignition of isobarically compressed D-T targets
Stefano Atzeni,A. Caruso +1 more
TL;DR: In this paper, an initial transient phase and the self-heating stage, burn in propagated mainly by α-particle transport, while the burning region is cooled at comparable rates by heat conduction and hydrodynamic expansion.
Journal ArticleDOI

TL;DR: In this paper, the effect of the fast electrons on the efficiency of the shock wave production is investigated in a series of dedicated experiments at the Prague Asterix Laser Facility (PALS).
Journal ArticleDOI
Laser acceleration of high-energy protons in variable density plasmas
Patrizio Antici,Patrizio Antici,Patrizio Antici,Julien Fuchs,Emmanuel d'Humières,Emmanuel d'Humières,J. Robiche,Erik Brambrink,Stefano Atzeni,Angelo Schiavi,Yasuhiko Sentoku,P. Audebert,Henri Pépin +12 more
TL;DR: In this article, the acceleration of protons induced by electrons generated by a short-pulse laser is investigated when varying the density of the plasma target the laser is interacting with, and the experimental results are compared with particle-in-cell (PIC) simulations for which the target conditions are inferred from hydrodynamic simulations.
Journal ArticleDOI
Three-dimensional study of radiation symmetrization in some indirectly driven heavy ion icf targets
Mauro Temporal,Stefano Atzeni +1 more
TL;DR: In this article, the authors investigated the effects of changing the area ratio, the size and position of the converters and the geometry of the hohlraum, and found that, for a practical casing to capsule area ratio (of the order of ten), two converters (allowing for two-side axisymmetric irradiation) cannot provide the uniformity required for ICF.
