U.S.-France Cooperative Research: Sources of Subpicosecond Soft X-Ray Pulses in the Energy Range 1-10KeV from Femtosecond Laser-Produced Plasmas

这一为期两年的奖项将支持内华达大学的罗伯托·曼奇尼和巴黎理工学院强激光利用实验室的让-克洛德·戈蒂耶在物理学方面的美法合作研究。该项目结合了在飞秒激光产生的等离子体和产生超短X射线脉冲方面的补充建模和实验工作。他们将研究与时间相关的原子动力学以及热电子的产生和衰减的影响。该项目汇集了互补的资源。内华达大学在激光产生的等离子体的理论和模型研究方面提供专业知识。此外，在巴黎理工大学最先进的激光设备上进行的实验工作也将作为补充。法国研究小组将专注于固体目标的辐照实验、诊断、目标演化的互补流体动力学模型以及热电子传输的蒙特卡洛模拟。这些实验的结果将推动内华达大学开发的动力学模型。该项目将增进对稠密等离子体物理的理解，这将有助于天体物理、材料科学和极端条件下的物质研究。

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.
