Résumé

Single (Al) and double (Al/Mg) foils have been irradiated with high energy laser pulses to study the radiative properties during the interaction of highly ionized plasma jets with gases and solids. X-ray microscopy with two-dimensional curved Bragg crystals was shown to provide a detailed topological structure with 15 μm resolution and a 5 cm large field of view. The realization of simultaneously high spectral resolution enabled to identify not only resonance and intercombination lines but even single satellite transitions. Gas pressure dependent emission features for resolved line transitions inside the jets of H-, He- and Li-like aluminum ions was discovered when the jet moves into the gas. In the case of two-foils, accumulation features near the non-irradiated target have been observed. At large distances from irradiated single foils, anomalous high (3 orders of magnitude) intensities of Li-like intercombination transitions from double excited states (satellite lines) have been identified in the front and rear side plasma. Charge exchange driven cascading in autoionizing states is proposed to explain the experimental findings.
