Recent experimental results on ion beams produced in high-intensity laser–solid interactions indicate the presence of very intense electric fields in the target. This suggests the possibility of efficiently heating a solid material by means of the

Increasing the range of plasma parameters accessible for laboratory absorption coefficients measurements is of interest for astrophysical applications. Aluminum is of special interest as its 1s–2p inner shell absorption transitions permit one to pr

An experimental and numerical analysis of the ionization dynamics of a freely expanding nanosecond laser-produced plasma is given. Point-projection X-ray absorption spectroscopy with picosecond time-resolution is used to provide a spatio-temporal map

Mixtures of light and mid- Z elements have been used to measure the absorption of the mid- Z element Ni, the temperature is inferred from the K-shell absorption of the light element Al. Here we test this method by comparing the temperatures deduced f

Time-resolved K-shell spectroscopy of an X-ray driven boron sample is reported. A small cavity irradiated by two frequency-doubled Nd:glass laser beams is used as an X-ray heating source, allowing to reach electron temperatures in the 10–25 eV rang

Several thin foils have been heated by X-ray radiation emitted by a small gold cavity irradiated with the LULI facility Nd glass laser. The foils were heated to moderate temperatures (10–25 eV) in conditions near local thermodynamic equilibrium. Me

Thin solid tamped foils were heated by the x-rays generated in spherical gold hohlraums which were irradiated by the high power laser ASTERIX IV with an energy of up to 500 J and a pulse duration of 0.4 ns. The sample foils were probed by the radiati

We present a new method for calculating opacities in a non-LTE plasma, based on modeling of the one-electron atomic potential in the framework of the “average atom” approach. In this model, the collisional-radiative equations of an average ion ar

A preliminary measurement of the opacity of a thin boron foil radiatively heated at moderate temperatures (5–20 eV) in conditions near local-thennodynamic-equilibrium (LTE) are reported. The opacity of a 0.37 μm thick boron sample has been measure
