TL;DR: It is inferred from a particle-in-cell simulation that the high energy ions are generated at the rear side of the target due to the formation of a strong dipole vortex structure in subcritical density plasmas.

TL;DR: In this article, a two-dimensional model was set up in order to calculate gas expansion and partial condensation into clusters, which was validated by experimental measurements using Mach-Zehnder interferometry and Rayleigh scattering, and performed with two types of nozzles.

TL;DR: In this article, high-resolution K-shell spectra of a plasma created by superintense laser irradiation of micron-sized Ar clusters have been measured with an intensity above 1019 W/cm2 and a pulse duration of 30 fs.

Spatially resolved x-ray spectroscopy investigation of femtosecond laser irradiated Ar clusters
G. C. Junkel-Vives,Joseph Abdallah,Thierry Auguste,Pascal D'Oliveira,S. Hulin,P. Monot,S. Dobosz,A. Ya. Faenov,A. I. Magunov,T. A. Pikuz,I. Yu. Skobelev,A. S. Boldarev,Vladimir A. Gasilov +12 more
TL;DR: Detailed spectroscopic analysis of spatially resolved, high resolution x-ray data near the He(alpha) line of Ar is consistent with a two-temperature collisional-radiative model incorporating the effects of highly energetic electrons.

TL;DR: In this article, the authors measured the X-ray emission spectra of a plasma generated by laser radiation with an intensity above 1019W/cm2 and a pulse duration of 30 fs acting upon an argon jet target with a large abundance of micron-sized clusters.
