Full description
This archive contains the SAXS data acquired in March 2014 at the SAXS/WAXS beamline Australian Synchrotron by Amelia Liu, Martin de Jonge, Stephen Mudie, Tim Petersen and Rico Tabor.
The x-ray beam energy was 5 keV. The beam was defined using a pair of Ge slits to limit divergence and a near-field tungsten aperture (20 micron OD). The specimens were 20 micron thick layers of colloidal glasses composed of SiO2 microspheres (300 nm OD) and sandwiched between two Kapton layers. A Kapton layer was used as the 20 micron spacer.
The archive contains:
- the raw micro-SAXS spatial scans (61x61 steps in 5 micron steps) (.tif in zipped folders)
- the structure factors and radial distribution functions (S(q) and g(r)) of the glasses (.csv)
- the average azimuthal symmetries derived from the first peak in the structure factor of the micro-SAXS patterns using the angular auto-correlation function (see ACY Liu et al PRL 110, 205505, (2013), and ACY Liu et al PRL 116, 205501 (2016)) (.txt magnitude;standard deviation;standard error;systematic error;total error (random and systematic)). ‘Even’ denotes symmetry magnitudes that have been corrected for dynamical diffraction according to the method outlined in ACY Liu et al Acta Cryst A 71, 473-482, (2015).
- the rotationally averaged projected symmetries of archetypal unit clusters used to decompose the symmetries of the glasses (.txt)
