Evolution of the relaxation time as a function the wave vector transfer.
(a). τ(q) obtained from the images with 1, 2, 10, 30 and 100 pulses per frame measured successively for a total 150 frames. (b). τ at q = 0.0123 Å−1 as a function of the the age at 393 K for the same data set in (a). (c). Plot of τ(q) with 100 pulses per frame but at different ages. Position on the sample was changed after each measurement. In (a), the τ(q)s get slower even with increasing number of pulses per frame, as emphasized in (b) for a particular q. In c, the waiting time between the measurements was longer than in (a) to see more clearly the effect of aging. The data for 232 min. was collected at higher q and the error bars are larger than other sets due to lower scattering intensity at high q.
