Studies on shock ignition targets for inertial fusion energy
TL;DR: In this article, one-dimensional and two-dimensional numerical simulations of a simple inertial fusion target with a simple all-DT HiPER baseline target (imploded mass of 0.29 mg) and a simple laser wavelength λ = 0.35 μm (0.25 μm) are considered.

Stefano Atzeni,C. Bellei,C. Bellei,J. R. Davies,Roger Evans,Roger Evans,J. J. Honrubia,Philippe Nicolai,Xavier Ribeyre,Guy Schurtz,Angelo Schiavi,Jan Badziak,Juergen Meyer-ter-Vehn,M Olazabal,L. O. Silva,G Sorasio +15 more
TL;DR: The HiPER facility has been proposed recently to demonstrate fast ignition of laser-driven inertial fusion targets as discussed by the authors, which has a 3ω, multi-beam, mult-ns-pulse of about 250 kJ and a 2ω or 3ω ignition beam delivering 70 kJ in about 15 ps.
Journal ArticleDOI
Improved robustness study of a shock ignited target, with DUED code including non-local electron transport and 3D laser ray-tracing
TL;DR: In this paper, the 2D DUED laser fusion code has been improved with the inclusion of a 3D laser ray-tracing scheme and a model for non-local electron transport.
Journal ArticleDOI
Heavy-ion fusion targets with «diffuse» spherical radiation converter
A. R. Piriz,Stefano Atzeni +1 more
TL;DR: In this paper, the authors derived the conditions for effective hydrodynamic decoupling and showed that with the use of heavy ions with energy about or below 8 GeV, the beam-to-fuel energy coupling efficiency can be as large as in foreseen conventional hohlraums.
Journal ArticleDOI

TL;DR: In this article, an integrated code that can simulate the entire evolution of a target with complex structure has been proposed to evaluate the feasibility of heavy ion-driven inertial confinement fusion ignition with beam energy below 2 MJ.
