A transmission grating streaked spectrograph (SPARTUVIX) has been developed at the Centre d’Etudes de Limeil‐Valenton for measuring the temporal evolution of soft‐x‐ray spectra in laser‐produced plasmas. In this article the ideas behind the instrument are described as well as a description of the actual working diagnostic and its relevant components. This diagnostic has been used to look at the time behavior of x‐ray laser emission, and a number of very interesting results have been obtained. A representative sample of these results will also be shown.

Spectroscopic diagnostic of an X-ray laser plasma by use of L-shell spectra

The x‐ray spectrum in the range of Ne‐like selenium resonance lines coming from a soft x‐ray laser plasma has been used to make a spectroscopic diagnostic of the plasma. We performed a modelization of the emission. Computing intensity ratios of Ne‐like resonance lines and Na‐like satellite lines, plasma parameters (density and temperature) have been obtained. The temperature deduced from the model is found to be lower than expected in hydrodynamical calculations from other authors.
