Relative timing of the pump lasers and XFEL pulses with Δt = 10 ms (a) and Δt = −50 ns (c). Schematic representations of the boundaries where the pump lasers reaching a slower flow rate with Δt = 10 ms (b) or Δt = −50 ns (d), and at a faster flow rate with Δt = −50 ns (e). Note that the region exposed to XFEL pulses interacts with multiple pump lasers (b) or an unintended laser (d) when a slower flow rate was employed. XFEL pulses that were not recorded for the `light' datasets are shown as dashed lines. The excitation region is shown as a triangle for clarity, but it is not a linear profile in the experiment.
