The stream of crystal-containing LCP is extruded from the LCP injector into the focus of the X-ray beam, formed by upstream optics (Kirkpatrick-Baez mirrors in this case). The LCP stream is kept straight by a coaxially flowing gas stream, indicated by the curved blue dashed lines. The X-ray beam is represented by the orange cylinder. Diffracted X-rays are measured by the detector (far left). The unscattered X-ray beam passes through a hole in the center of the detector. The LCP injector and CSPAD detector are located inside a sample vacuum chamber (dotted line). Adapted from (ref. 3).
