Prospect of Photo-Pumping Experiment with XFEL Source in a Hot and Dense Plasma

Résumé

The development of the fourth generation light sources based on the X-ray free electron laser (XFEL) opens new perspectives in the investigation of high-energy-density plasmas. The properties of these tunable X-ray laser sources permit to consider an active spectroscopy experiments to improve the understanding of hot and dense plasmas. In this work, we present prospective calculations of spectral line shapes and redistribution functions of the neon-like aluminum 1s2s(2)2p(6)nl - 1s(2)2s(2)2p(5)nl, (n = 3, 4, 5, ..) and 1s2s(2)2p(6)3l - 1s(2)2s(2)2p(6) lines at 1490 eV and 1572 eV, respectively, for typical laser-plasma conditions. These calculations are based on a theoretical model for calculating the redistribution function in hot and dense plasmas. It relies on an extension of the Frequency Fluctuation of Model. This model takes into account the complexity of the atomic structure of ionic emitters and the various line broadening mechanisms including effects of the emitter environment fluctuations.
