(a) Time autocorrelation function from a statically disordered aerogel sample measured using the traditional channel-cut (open circles) and artificial channel-cut (open squares) monochromators at wavevector transfer q = 0.4 nm−1. (b) Time stability limit of the experimental set-up as a function of wavevector transfer q measured using the traditional channel-cut (open circles) and artificial channel-cut (open squares) monochromators. |
