In this work we present our preliminary results of spectroscopic investigations of plasmas produced by the NHELIX laser facility (140 Joules in 14 ns, λ = 1.064 nm.) at GSI, Darmstadt. The measurements have employed two mica spectrometers with a resolution λ / Δ λ of 3000 at wavelengths less than 2 nm. Spectrographic data were used to achieve space resolved information about the ion velocity distribution, electron density and electron temperature inside the plasma.
