Journal ArticleDOI
Driving high-gain shock-ignited inertial confinement fusion targets by green laser light
TL;DR: In this article, an analytical model is derived, allowing to rescale UV-driven targets to green light, and gain in the range 100-200 is obtained for total laser energy of the order of 1.5-3 MJ.
Journal ArticleDOI
Experimental evidence for the enhanced and reduced stopping regimes for protons propagating through hot plasmas.
Sophia Chen,Stefano Atzeni,T. Gangolf,T. Gangolf,Maxence Gauthier,Maxence Gauthier,Drew Higginson,Drew Higginson,R. Hua,Joungmok Kim,F. Mangia,C. McGuffey,J.-R. Marquès,R. Riquier,H. Pépin,Ronnie Shepherd,Oswald Willi,Farhat Beg,Claude Deutsch,Julien Fuchs +19 more
TL;DR: By reducing the energy bandwidth of the protons using a passive selector, proton stopping measurements are made in partially ionized Argon and fully ionized Hydrogen plasmas with electron temperatures of hundreds of eV and densities in the range 1020–1021 cm−3 and enhanced stopping of protons when compared to stopping power in non-ionized gas.
Journal ArticleDOI
Monochromatic short pulse laser produced ion beam using a compact passive magnetic device
Sophia Chen,Maxence Gauthier,Drew Higginson,S. Dorard,F. Mangia,R. Riquier,Stefano Atzeni,Jean-Raphael Marques,Julien Fuchs +8 more
TL;DR: An adaptation of conventional chicane devices in a compact form which enables selection of a specific energy interval from the broadband spectrum by employing magnetic fields to bend the trajectory of the laser produced proton beam through two slits in order to select the minimum and maximum beam energy.
Journal ArticleDOI
Theoretical and Experimental Studies of Radiative Shocks
C. Michaut,Tommaso Vinci,L. Boireau,M. Koenig,Serge Bouquet,Alessandra Benuzzi-Mounaix,N. Osaki,G. Herpe,Emeric Falize,Berenice Loupias,Stefano Atzeni +10 more
TL;DR: In this article, the authors deal with the radiative shock from both theoretical and numerical points of view, based on the whole experimental results obtained at LULI, Ecole Polytechnique.
Journal ArticleDOI
Nonlinear evolution of localized perturbations in the deceleration-phase Rayleigh-Taylor instability of an inertial confinement fusion capsule
Angelo Schiavi,Stefano Atzeni +1 more
TL;DR: In this article, the evolution of axially symmetric localized perturbations in the deceleration-phase Rayleigh-Taylor instability of an inertial confinement fusion shell capsule is studied by two-dimensional simulations.
