This two-year award will support U.S.-France cooperative research in physics between Roberto Mancini of the University of Nevada and Jean-Claude Gauthier of the Ecole Polytechnique's Laboratory for the Utilization of Intense Lasers. The project combines complementary modeling and experimental work in the area of femtosecond laser-produced plasmas and in the generation of ultra short- X-ray pulses. They will study the effects of time-dependent atomic kinetics and hot-electron production and attenuation. The project brings together complementary resources. The University of Nevada offers expertise in theory and modeling research in laser-produced plasmas. This will be complemented by experimental work performed on a state-of-the-art laser facility at the Ecole Polytechnique. The French research group will focus on experiments of irradiation of solid targets, diagnostics, complementary hydrodynamic modeling of target evolution, and Monte Carlo simulations of hot-electron transport. Results from these experiments will drive kinetic models developed at the University of Nevada. The project will advance understanding of dense plasma physics that will be beneficial to research in astrophysics, materials science, and studies on matter in extreme conditions.

这项为期两年的奖励将支持美国-法国内华达州大学的Roberto Mancini和Ecole Polytechnique's Laboratory for the Utilization of Intense Lasers的Jean-Claude Gauthier在物理学方面的合作研究。 该项目结合了飞秒激光产生等离子体和超短X射线脉冲产生领域的互补建模和实验工作。 他们将研究随时间变化的原子动力学和热电子产生和衰减的影响。 该项目汇集了互补资源。 内华达州大学提供激光产生等离子体的理论和建模研究方面的专业知识。 这将通过在Ecole Polytechnique最先进的激光设施上进行的实验工作来补充。 法国研究小组将重点研究固体靶照射实验、诊断、靶演变的补充流体动力学建模以及热电子输运的蒙特卡罗模拟。 这些实验的结果将驱动内华达州大学开发的动力学模型。 该项目将促进对稠密等离子体物理学的理解，这将有利于天体物理学，材料科学和极端条件下物质的研究。
