Figure 2
Collection of a zoomed-in region of detector images collected during an energy scan using the flow cell without flow (left column) and with flow (right column). Without flow, one can clearly observe a bubble forming after ca. 150 s of exposure to X-rays (black arrow). Each image depicts a real-space image of the X-ray beam as it impinges through the liquid water sample in the direction perpendicular to the water flow through a quartz glass capillary, the diameter of which is 2 mm. |
