Comparison for non-local hydrodynamic thermal conduction models
Alberto Marocchino,Michail Tzoufras,Stefano Atzeni,Angelo Schiavi,Ph. Nicolaï,J. Mallet,Vladimir Tikhonchuk,Jean-Luc Feugeas +7 more
TL;DR: In this paper, two non-local electron thermal conduction models are tested against kinetic Vlasov-Fokker-Planck simulations, and the reduction of the thermal conductivity as a function of the scalelength of the temperature gradient is also recovered.
Journal ArticleDOI
Fast Ignition: Overview and Background
TL;DR: Fast ignition is an approach to inertial fusion in which precompressed fuel is ignited with an external heat source as mentioned in this paper, which can, in principle, lead to higher gains than conventional ignit...
Journal ArticleDOI
Radiative shocks : An opportunity to study laboratory astrophysics
M. Koenig,Tommaso Vinci,Alessandra Benuzzi-Mounaix,Norimasa Ozaki,Alessandra Ravasio,M Rabec Le Glohaec,L. Boireau,C. Michaut,S. Bouquet,Stefano Atzeni,Angelo Schiavi,Olivier Peyrusse,Dimitri Batani +12 more
TL;DR: In this article, experimental results on radiative shocks generated by a high power laser in a xenon gas cell are presented and compared with 1D and 2D radiative hydrodynamic simulations.
Journal ArticleDOI

TL;DR: In this paper, an experiment was performed using the PALS laser to study laser-target coupling and laser-plasma interaction in an intensity regime ≤1016W/cm2, relevant for the "shock ignition" approach to Inertial Confinement Fusion.
Journal ArticleDOI
Overview of ignition conditions and gain curves for the fast ignitor
Stefano Atzeni,Max Tabak +1 more
TL;DR: In this article, the authors review and discuss ignition requirements, burn studies, and gain models, and present selected gain results, illustrating the dependence of the gain on the parameters of the ignition beam.
