TL;DR: The National Ignition Facility has been used to compress deuterium-tritium to an average areal density of ~1.0±0.1 g cm(-2), which is 67% of the ignition requirement.

TL;DR: In this paper, the authors measured high resolution copper Kα spectra from a picosecond high intensity laser produced plasma by fitting the shape of the experimental spectra with a self-consistent field model which includes all the relevant line shifts from multiply ionized atoms.

TL;DR: It is shown that soft-x-ray emission spectroscopy measurements reveal the electronic temperature and density of this highly excited system immediately after the excitation pulse, with detailed calculations of the electronic structure, based on finite-temperature density functional theory, in good agreement with the experimental results.

TL;DR: In this article, the formation of turbulent collisionless shocks in conditions relevant to young supernova remnants is investigated. And the authors show that electrons can be effectively accelerated in a first-order Fermi process by small-scale turbulence produced within the shock transition to relativistic non-thermal energies, helping overcome the injection problem.

TL;DR: The sensitivity of the elastic scattering component to carbon K-shell ionization is demonstrated while at the same time constraining the temperature of the dense plasma, indicating that widely used ionization models need revision in order to be suitable for the extreme states of matter tested in this experiment.
