Abstract

One of the most challenging aspects of X-ray research is the delivery of liquid sample flows into the soft X-ray beam. Currently, cylindrical microjets are the most commonly used sample injection systems for soft X-ray liquid spectroscopy. However, they suffer from several drawbacks, such as complicated geometry due to their curved surface. In this study, we propose a novel 3D-printed nozzle design by introducing microscopic flat sheet jets that provide micrometre-thick liquid sheets with high stability, intending to make this technology more widely available to users. Our research is a collaboration between the EuXFEL and MAX IV research facilities. This collaboration aims to develop and refine a 3D-printed flat sheet nozzle design and a versatile jetting platform that is compatible with multiple endstations and measurement techniques. Our flat sheet jet platform improves the stability of the jet and increases its surface area, enabling more precise scanning and differential measurements in X-ray absorption, scattering, and imaging applications. Here, we demonstrate the performance of this new arrangement for a flat sheet jet setup with X-ray photoelectron spectroscopy, photoelectron angular distribution, and soft X-ray absorption spectroscopy experiments performed at the photoemission endstation of the FlexPES beamline at MAX IV Laboratory in Lund, Sweden.

开发用于 MAX IV 软 X 射线光谱分析的平面射流传输系统。

X 射线研究中最具挑战性的方面之一是将液体样品流输送到软 X 射线束中。目前，圆柱形微射流是软 X 射线液体光谱学最常用的样品注入系统。然而，圆柱形微射流存在一些缺点，例如由于表面弯曲，几何形状复杂。在本研究中，我们提出了一种新颖的三维打印喷嘴设计，引入了可提供微米厚液片且稳定性高的微型平板喷嘴，旨在使这项技术更广泛地为用户所用。我们的研究是 EuXFEL 和 MAX IV 研究设施之间的一项合作。这项合作旨在开发和完善三维打印的平板喷嘴设计和多功能喷射平台，该平台与多个终端站和测量技术兼容。我们的平板喷射平台提高了喷射的稳定性并增加了其表面积，从而能够在 X 射线吸收、散射和成像应用中进行更精确的扫描和差分测量。在这里，我们通过在瑞典隆德 MAX IV 实验室 FlexPES 光束线的光发射端站进行的 X 射线光电子能谱、光电子角分布和软 X 射线吸收光谱实验，展示了这种新布置的平板射流装置的性能。
