High resolution X-ray spectroscopy of laser generated plasmas

The application of recently developed spectroscopic instruments in laser pr oduced plasmas with simultaneous high spectral and spatial resolution combi ned with high luminosity discovered new types of X-ray spectra. These new t ypes are characterised by the disappearance of the resonance lines and the strong emission of dielectronic satellite spectra. Several types of transit ions of highly charged ions are discovered which are unknown from usual sou rces employed in atomic physics. New theoretical models are developed and s uccessfully applied for the interpretation and for plasma diagnostics.
