TL;DR: This work proposes and implements a means to drive fusion reactions between protons and boron-11 nuclei by colliding a laser-accelerated proton beam with a Laser-generated borons plasma, and demonstrates a new means for exploring low-energy nuclear reactions such as those that occur in astrophysical plasmas and related environments.

TL;DR: In this paper, the authors present theoretical analysis and experimental results concerning the major physical issues in the shock-ignition approach, which are the following: generation of a high amplitude shock in the imploding target, laser-plasma interaction physics under the conditions of high laser intensities needed for high-amplitude shock excitation, symmetry and stability of the shock propagation, role of fast electrons in the symmetrization of shock pressure and the fuel preheat.

TL;DR: This Letter presents first experimental results of the laser imprint reduction in fusion scale plasmas using a low-density foam layer, reproducing the conditions of the initial interaction phase in the direct-drive scheme.

TL;DR: In this article, a set of materials (titanium, copper, and germanium) have been experimented with at the OMEGA laser facility by irradiating thin foils with a prepulse prior to a main pulse with variable delay, in order to design efficient x-ray laser sources for backlighting, material testing, and code validation.

TL;DR: Thomson scattering measurements are presented which demonstrate conclusively the occurrence of the Langmuir decay instability (LDI) in a laser-produced plasma experiment and the connection with growth and saturation of the stimulated Raman instability is discussed.
