Results of static and dynamic analysis from a colloidal suspension of 70 nm latex spheres dispersed in glycerol at a volume fraction of 1% measured with a Medixpix3-based LAMBDA detector are shown. The circular object is the 3 mm-diameter beam stop used to block the main beam from hitting the detector, and the horizontal and vertical bands are the dead regions between the modules in the detector array. (a) Time-averaged 2-D scattering pattern. (b) A pseudo color plot showing the digitized wavevector maps where each color corresponds to a mean wavevector value such that the range 0.02–0.2 nm−1 is divided into 140 linearly spaced wavevector bins. (c) Integrated scattering intensity over the user-specified area of interest plotted as a function of time which is typically used to assess for beam-induced damage to the sample. (d) Radially averaged small-angle X-ray scattering pattern as a function of wavevector. (e) Correlation functions (circles) along with simple exponential fits (solid lines) at wavevector values of 0.02, 0.03, 0.04 and 0.05 nm−1 in decreasing order of delay time. (f) Two-time correlation function computed at a wavevector value of 0.03 nm −1. |
