X-ray diffraction data of 15 pairs of delayed probe and reference pulses.
The data were taken with the set-up sketched in Fig. 1 using a Bi <111> crystal as sample. The black curve shows the average over twelve XFEL shots, while the coloured curves are single shot data. The curves are shown on a linear scale and are offset in the vertical direction for clarity. The grey regions mark the channels that were reduced in transmission by additional attenuators (not shown in Fig. 1) on the Rn gratings in order to make better use of the dynamic range of the strip detector. The direct pump beam was completely blocked. The insets show probe and reference signals for long delays (n ≥ 6, Δt ≥ 243 fs).
