This article sums up the theoretical and experimental studies about ignition. Three experiments are salient this year on the Omega laser in collaboration with DOE laboratories (1) 3 cones of beams allow to mimic the LMJ configuration and to get symme

The National Ignition Facility neutron imaging system (NIS) is an important diagnostic for understanding ignition experiments at the NIF in late 2010. The goal of the diagnostic is to provide spatially resolved information on the production of prompt

A new neutron diagnostic has been designed to achieve high energy neutron spectroscopy in large γ background. The concept is based on the association of a Micromegas detector with a neutron-to-charged particle converter. Studies have been performed

We demonstrate 325 μm spatial resolution in a 14 MeV neutron detector made with a capillary array filled with a deuterated liquid scintillator. A 10 μm source resolution in an image formed by 14 MeV neutrons is now achievable on a 25 m line-of-sigh

Neutron images have been successfully recorded with “gel-type bubble detectors.” 14 MeV fusion neutrons emitted from laser-irradiated inertial confinement fusion targets formed coded images in proof-of-principle experiments conducted at the OMEGA

The fraction of low-energy neutrons created from 14 MeV neutrons by elastic scattering and (n,2n) reactions on D and T has been proposed as a measure of the areal density 〈ρr〉 (radial integral of density) of ICF targets. In simple situations the

The results of proof-of-principle neutron imaging experiments using bubble detectors are reported. Bubble detectors, which detect neutrons with a spatial resolution as small as 5 μ, were used to image the neutrons from laser-driven compressed deuter

Neutron emission as high as ${10}^{7}$ is observed when a high intensity (a few ${10}^{19}\mathrm{W}/{\mathrm{cm}}^{2}$) subpicosecond laser pulse at 529 nm wavelength is focused on a deuterated polyethylene target. Neutron emission is also measured
