Figure 3
(a) Correlations obtained after 4.4 µs (circles), 13.3 µs (diamonds) and 62.0 µs (squares) hitting the sample with a fluence of 3.9 mJ mm−2 (blue symbols) and 10.5 mJ mm−2 (red symbols). The black lines are exponential fits to the data. Within the sensitivity given by the XFEL intensity fluctuations, the dynamics within a train of pulses remain stationary for the lower fluence, whereas in the higher fluence the relaxations are faster for larger t1. For clarity only the correlations from one q of sample B are reported, but other qs in other samples provide the same qualitative information. The error bars on the data points are obtained from the variance of the two-time correlation matrix. (b) ![]() |
