Since the operational commissioning of the Laser Megajoule (LMJ) in October 2014, several experimental campaigns have been achieved, with the first eight beams, and demonstrated LMJ’s aptitudes for the Simulation Program.
The Simulation Program of the Commissariat à l’Energie Atomique et aux Energies Alternatives (CEA) combines improvement of physics models, high performance numerical...

Here we report recent experimental results relevant to the fast ignition (FI) inertial confinement fusion assisted with external kilo-tesla magnetic field. We have experimentally observed generation of 0.6 kT of magnetic field by using laser-driven capacitor-coil scheme, short diffusion time (<< 1 ns) of laser-generated magnetic field into a target material, reduction of the REB beam diameter...

Hot-spot ignition planned at the National Ignition Facility (NIF) requires proper assembly of the DT fuel, as manifested by the evolution of areal density (ρR) symmetry and hot-spot ion temperature (Ti). Ideally, a spherically symmetric layer of cold and dense fuel with a ρR exceeding 1 g/cm2 surrounding a ~5 keV lower-density hot spot is obtained at peak convergence. To reach these...

Fusion fast ignition assisted by laser-driven ion beams requires 10 kJ energy deposition onto the fuel core having ~500 g/cm^3 densities. Assuming 100 kJ as a technically manageable energy of the driving laser, the first milestone can be found on 10% conversion efficiency from the laser energy into ions having kinetic energies of 10-30 MeV/u.
In this paper, we experimentally investigate the...

Implosions of thin-shell capsules produce strongly-shocked (M > 10), low-density (ρ ~ 1 mg/cc), high-temperature (Ti ~ keV) plasmas, comparable to those produced in the strongly-shocked DT-vapor in inertial confinement fusion (ICF) experiments. A series of thin-glass targets was filled with mixtures of deuterium and Helium-3 gas ranging from 20% to 100% deuterium and imploded on the OMEGA...

A new heating laser for fast ignition, called the LFEX-Laser, has been demonstrated with all four beams. The obtained total pulse energy was 2 kJ for a 1 ps pulse duration. The peak power of 2 PW is the highest of all kilojoule lasers in the world and was achieved with a high intensity contrast ratio of 1 × 10^10.
To increase the pulse energy to the kilojoule class in a short pulse of 1–2 ps,...
