Figure 3
Intensity–intensity correlation function, g2(q, t), of a LiBO2 glass mounted on the UHF1 chip in `orthogonal' (a) and `parallel' (b) configuration. A difference in contrast is observable due to the different lengths of the samples along the beam, but the relaxation times (τO = 10.9 ± 0.3 s and τP = 11.2 ± 0.5 s for the orthogonal and parallel configurations, respectively) and the shape parameters (γO = 1.27 ± 0.08 and γP = 1.43 ± 0.13 for the orthogonal and parallel configuration, respectively) are compatible within one standard deviation. Both measurements have been performed on the first sharp diffraction peak at q = 17.0 ± 0.9 nm. The insets in the panels show the beam direction with respect to the calorimeter's chip.
