TL;DR: In this article, a series of high-resolution three-dimensional simulations of two initial conditions with eight independent codes is presented, where the simulations are initialised with a narrowband perturbation such that instability growth is due to nonlinear coupling/backscatter from the energetic modes, thus generating the lowest expected growth rate from a pure RMI.
Journal ArticleDOI
Thermonuclear targets for direct-drive ignition by a megajoule laser pulse
S. A. Bel’kov,S V Bondarenko,G. A. Vergunova,Sergey G Garanin,S. Yu. Gus’kov,S. Yu. Gus’kov,N. N. Demchenko,I. Ya. Doskoch,P. A. Kuchugov,N. V. Zmitrenko,Vladislav B Rozanov,R. V. Stepanov,R. A. Yakhin +12 more
TL;DR: In this article, the central ignition of a thin two-layer shell fusion target that is directly driven by a 2-MJ profiled pulse of Nd laser second-harmonic radiation has been studied.
Journal ArticleDOI
Discontinuous Galerkin method on three-dimensional tetrahedral grids: Using the operator programming method
TL;DR: This example demonstrates that the method in question can be efficiently implemented on arbitrary three-dimensional grids and demonstrates the use of the template metaprogramming methods of the C++ programming language in order to speed up computations.
Journal ArticleDOI

TL;DR: In this article, the results of theoretical investigation of compression and burning of spherical direct-drive targets in the conditions of spatial nonuniformity of heating associated with a shift of the target from the beam center of focusing and possible laser radiation energy disbalance in the beams are reported.
