Abstract
The main question this thesis addresses is if aXPCS can follow atomic jumps in glasses. As a showcase material, the binary network former lead silicate glass was chosen. An important question arising for this material is how the dynamics are connected to the network forming properties of its components. To show that this question can indeed be addressed with aXPCS, the following route was taken: First, glass samples in both network forming regions of lead silicate glass were produced. Then, both samples were studied with coherent X-rays. Finally, appropriate models for the dynamics were found and tested, yielding insight into the change in dynamics with the change in structure of the studied material. The results presented here were published recently (Ross et al., New Journal of Physics 16(9), 093042, 2014).
