Abstract

Thomson scattering, x-ray diagnostics and optical interferometry are employed to characterize both collisionally excited and recombination x-ray laser plasmas. Spatially and timeresolved Thomson scattering spectra from carbon plasmas provide the electron and ion temperatures, which are compared with hydrodynamic computer modelling. The electron density is inferred from the recorded interferograms. Time-integrated X-ray spectra in the keV range are used to characterize very precisely the optimum irradiance conditions for lasing in Ne-like germanium plasmas. Also, electron temperatures obtained with the 5C/4C line ratio, assuming a PLTE model, are compared to Thomson scattering results.
