a Top: EuXFEL pulse structure for the early user experiment phase in which this experiment was carried out. Middle: Schematic of the segmented flow with droplets of mother liquor carrying crystals formed in an oil phase. Bottom: Schematic representation of the liquid stream leaving the GDVN, where the liquids are stretched out to form a thin jet. The stretched out droplets are larger than a pulse train of ~30 µs. b Schematics of the fluidic components needed to achieve segmented droplet injection at the SPB/SFX chamber (distances for each fluidic line are indicated and are approximate). c Brightfield optical microscopy image of an assembled droplet generator. d Schematic of the droplet detector and representative components: laser diode (LD), collimating lens (CL), pinhole (PH), and photodetector (PD). e Representative voltage plot of the optical detector for aqueous-in-oil droplets. Scale bar is 100 µm in c. Source data are provided as a source data file.
