X-ray spectroscopy and imaging of hot dense plasma created by colliding foils. Simulation of spectra

Abstract

A simple strategy is presented to create moderately coupled plasmas: it consists in a colliding foil system irradiated by two laser beams. In these correlated plasmas, signatures of transient molecular behaviour are shown. Two studies are intensively developed here: the simulation of the experiment and the X-ray spectroscopic and imaging diagnostics. A reciprocal action between the two studies allows an optimization of both the compression and the associated dense plasma effects. We present accurate fluorine Lyβ spectra as an appropriate example for the exhibition of the non-spherical symmetry of the bound electronic structure.
