Fig. 4: Intensity autocorrelation function g₂ measured at Q = 0.028 nm⁻¹ from all three sample setups.

The black solid line shows the fit to the exponential function and the black dashed line in the inset figure shows the fit to the Einstein–Stokes equation. The 3.7-μs-resolved Burst Mode acquisition from the capillary setup is synchronized with the APS clock frequency to ensure that each detector frame has the same number of x-ray pulses
