Abstract: One of the most challenging aspects of X-ray research is the delivery of liquidsample flows into the soft X-ray beam. Currently, cylindrical microjets are themost commonly used sample injection systems for soft X-ray liquid spectro-scopy. However, they suffer from several drawbacks, such as complicatedgeometry due to their curved surface. In this study, we propose a novel 3D-printed nozzle design by introducing microscopic flat sheet jets that providemicrometre-thick liquid sheets with high stability, intending to make this tech-nology more widely available to users. Our research is a collaboration betweenthe EuXFEL and MAX IV research facilities. This collaboration aims todevelop and refine a 3D-printed flat sheet nozzle design and a versatile jettingplatform that is compatible with multiple endstations and measurement tech-niques. Our flat sheet jet platform improves the stability of the jet and increasesits surface area, enabling more precise scanning and differential measurementsin X-ray absorption, scattering, and imaging applications. Here, we demonstratethe performance of this new arrangement for a flat sheet jet setup with X-rayphotoelectron spectroscopy, photoelectron angular distribution, and soft X-rayabsorption spectroscopy experiments performed at the photoemission end-station of the FlexPES beamline at MAX IV Laboratory in Lund, Sweden
