Micro-SAXS colloidal glasses February 2018

This archive contains the SAXS data acquired in February 2018 at the SAXS/WAXS beamline Australian Synchrotron by Amelia Liu, Espen Bojesen, Stephen Mudie, Tim Petersen and Rico Tabor.The x-ray beam energy was 5.5 keV. The beam was defined using a near-field tungsten aperture (12 microns thick and 7.5 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:- Cropped micro-SAXS diffraction patterns (256x256) from spatio-temporal scans in .tif format for glasses that have been aged for 2 days and 20 days, and before and after compression.- The aged glasses are scanned with 2 micron steps and a time internal of 1040 s, and the before/after deformation scans are taken with 4 micron spatial steps and a time interval of 2250 s. Files are named according to this convention 'dp_t_x_y.tif' where t is the timestep and x and y are the spatial steps in the x and y directions.- Scanned areas were chosen where the glass thickness was homogeneous and visible fibres/dust etc could not be seen.
