Abstract Spectrochemistry is the instrumental analysis of substances with light pulses. High brightness beams such as lasers, capillary discharges, etc. have dramatically contributed to the advancement of spectrochemistry, and largely replaced traditional continuous wave lamps. To extend this progress, intense pulses of even shorter wavelengths than state-of-the-art, such as in the extreme ultraviolet or soft/hard X-ray regions, are necessary. With that, one is able to carry out tabletop spectroscopy with high resolution in space, time and frequency. Unfortunately, such advanced beams are not yet commercially available but only found at synchrotron beamlines. Here, the user access is discontinuous, granted to large teams (”big science”), and mainly dedicated to proof-of-principle experiments. To fill the 24/7 gap between users and tools, prototypes of high-brightness short-wavelength sources for tabletop operation, have been developed. Complementary figures-of-merit make them unique for specific high resolution domains, such as generating tunable hard X-rays, monochromatic lines, or ultrafast pulses. Advantages of these tabletop high-brightness short-wavelength sources for spectroscopy are discussed as well as their limitations.

用于短波长光谱化学的桌面光束

摘要 光谱化学是利用光脉冲对物质进行仪器分析。激光、毛细管放电等高亮度光束极大地促进了光谱化学的进步，并在很大程度上取代了传统的连续波灯。为了扩大这一进展，需要比现有技术更短波长的强脉冲，例如在极紫外或软/硬 X 射线区域。有了它，人们就能够在空间、时间和频率上进行高分辨率的桌面光谱分析。不幸的是，这种先进的光束尚未商业化，只能在同步加速器光束线上找到。在这里，用户访问是不连续的，授予大型团队（“大科学”），主要用于原理验证实验。为了填补用户和工具之间 24/7 的空白，用于桌面操作的高亮度短波长光源原型已经开发完成。互补的品质因数使它们在特定的高分辨率域中独树一帜，例如生成可调谐硬 X 射线、单色线或超快脉冲。讨论了这些用于光谱学的桌面高亮度短波长源的优点及其局限性。
