Soft x-ray spectro-microscopy with a lab-scale source (C04)

在项目C04的下一阶段，我们将使用紧凑，无碎片和长期稳定的激光产生等离子体源在软X射线范围内研究高分辨率显微镜和空间分辨近边缘X射线吸收精细结构（NEXAFS）光谱。将迄今为止单独研究的水窗显微镜与NEXAFS光谱仪合并，将使高空间分辨率和化学灵敏度能够研究各种有机和无机样品系统。为了达到这一目标，实验室光源的亮度将通过使用皮秒激光器和重新设计靶系统来增加，以提高分辨率、对比度和效率。

In the next phase of project C04 we will investigate high resolution microscopy and spatially resolved near-edge x-ray absorption fine structure (NEXAFS) spectroscopy in the soft x-ray range using a compact, debris-free and long-term stable laser-produced plasma source. Merging the up to now separately investigated ¿water window¿ microscope with the NEXAFS spectrometer will enable both high spatial resolution and chemical sensitivity to study various organic and inorganic sample systems. To reach this goal, the brilliance of the laboratory source shall be increased by employing picosecond lasers and redesigning the target system in order to improve resolution, contrast and efficiency.
