在OMEGA EP激光设备中使用Talbot-Lau X射线偏转仪（TXD），通过莫尔偏折法绘制电子密度>1022 cm-3，表征辐照箔烧蚀前沿的演变。该实验使用短脉冲激光（30-100 J，10 ps）和箔铜靶作为X射线背光光源。在对诊断平台进行基准测试的第一次实验测试中，证明了光栅的存活率，并描述了提供莫尔图像的X射线背光灯激光参数。讨论了使用EP-TXD诊断平台通过TXD准确探测消融前沿的必要修改。
A Talbot-Lau X-ray Deflectometer (TXD) was implemented in the OMEGA EP laser facility to characterize the evolution of an irradiated foil ablation front by mapping electron densities >1022 cm-3 by means of Moiré deflectometry. The experiment used a short-pulse laser (30-100 J, 10 ps) and a foil copper target as an x-ray backlighter source. In the first experimental tests performed to benchmark the diagnostic platform, grating survival was demonstrated and x-ray backlighter laser parameters that deliver Moiré images were described. The necessary modifications to accurately probe the ablation front through TXD using the EP-TXD diagnostic platform are discussed.
