“…The ability to smooth the laser inhomogeneities by distributing the laser energy inspired new schemes for ICF [132] and has been confirmed experimentally [77,134,135] . Foams have found many more applications over the decades, as neutron sources [136] , as pressure amplifiers for equation-of-state studies [137] for extremely bright electron and X-γ radiation sources [138][139][140][141] and have been suggested to be used to reproduce the long plasmas expected in the corona of a fusion capsule in the direct-drive scheme [142] .…”

The recent achievement of fusion ignition with laser-driven technologies at the National Ignition Facility sets a historic accomplishment in fusion energy research. This accomplishment paves the way for using laser inertial fusion as a viable approach for future energy production. Europe has a unique opportunity to empower research in this field internationally, and the scientific community is eager to engage in this journey. We propose establishing a European programme on inertial-fusion energy with the mission to demonstrate laser-driven ignition in the direct-drive scheme and to develop pathway technologies for the commercial fusion reactor. The proposed roadmap is based on four complementary axes: (i) the physics of laser–plasma interaction and burning plasmas; (ii) high-energy high repetition rate laser technology; (iii) fusion reactor technology and materials; and (iv) reinforcement of the laser fusion community by international education and training programmes. We foresee collaboration with universities, research centres and industry and establishing joint activities with the private sector involved in laser fusion. This project aims to stimulate a broad range of high-profile industrial developments in laser, plasma and radiation technologies along with the expected high-level socio-economic impact.

“…Computational and theoretical studies in this area are carried out for targets of various designs and different approaches to ignition. Many important results of these studies relating to direct-drive ignition using modern laser facilities can be found in [29][30][31][32][33][34][35][36][37][38][39][40][41][42]. The problem statement itself depends on the target irradiation geometry with a specific laser facility.…”

The paper is devoted to the numerical and theoretical study of compression and burning of a thermonuclear target under the conditions of inhomogeneous heating due to direct irradiation with a multi-beam megajoule laser facility. The two-dimensional distribution of absorbed laser energy has been numerically calculated taking into account refraction and various known factors of the violation of irradiation homogeneity. The limits of the violation of irradiation uniformity caused by these factors, which are acceptable for spark ignition of the target irradiated with 192 laser beams of the modern megajoule facilities, are determined. The target offset relative to the aiming point of the laser beams should not exceed 2% of the target radius, mispointing of the beams (5% of the target radius), mistiming of the laser pulses (3% of the pulse duration) and energy imbalance among the laser clusters (12%). These values exceed the permissible deviations for the laser facility being developed within the frameworks of the project.

“…The physics of laser interaction with low average density porous materials is of major importance for many applications, in part icular for high energy density physics and inertial confinement fusion (ICF). Metaldoped foams and aerogels are considered as promising bright sources of xray emission for radiography [1,2], or sources of energetic electrons and ions [3][4][5]; foam coating of inertial fusion targets is proposed for suppression of the laser beam imprint in the direct drive ICF scheme [6][7][8]; foamfilled hohlraums [9] may be used to improve lasertarget coupling and to minimize wall expansion in indirect drive ICF.…”

“…It is assumed that the interaction of the intense laser or xray radiation with porous materials proceeds in three steps: ionization of solid elements, their expansion, pore filling and subsequent homogenization of the heated plasma [7]. The process of foam transformation in plasma propagates from the radiation source as an ionization wave with the structure depending on the source intensity and the target density.…”

A model is developed for numerical simulations of laser absorption in plasmas made of porous materials, with particular interest in lowdensity foams. Laser absorption is treated on two spatial scales simultaneously. At the microscale, the expansion of a thin solid pore wall is modeled in one dimension and the information obtained is used in the macroscale fluid simulations for the description of the plasma homogenization behind the ionization front. This twoscale laser absorption model is implemented in the arbitrary Lagrangian-Eulerian hydrocode PALE. The numerical simulations of laser penetration into lowdensity foams compare favorably with published experimental data.
