Fig. 51: Demonstration of transverse X-ray coherence effects in the time domain. The nuclear forward scattering from a stainless steel foil rotation at 33 Hz shows a faster decay than when the foil is at rest. Solid lines are fits to the data, including the synchrotron source size and the effect of slits limiting the sample size and detector aperture.

(The minimum at t ~ 55 ns is due to using a thick foil and is not of interest here).
