X-ray emission diagnostics of the densest part of plasma at laser-exploded foils

Abstract

K-shell emission spectra from laser-exploded aluminum foils and mylar foils with aluminum dots are recorded with a high spectral and spatial resolution using vertical-geometry Johann spectrometer. The experiments are modelled using cylindrical version of two-dimensional hydrocode "ATLANT." We describe our novel atomic physics post-processor "XEPAP" that is used here for the synthesis of the emission spectra. The predictions of the simulations are compared with the experimental spectra and the parameters of the emitting plasmas are deduced.
