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.本归档文件包含2018年2月由Amelia Liu、Espen Bojesen、Stephen Mudie、Tim Petersen与Rico Tabor在澳大利亚同步辐射装置（Australian Synchrotron）的小角X射线散射/广角X射线散射（Small Angle X-ray Scattering/Wide Angle X-ray Scattering，SAXS/WAXS）光束线采集的小角X射线散射（Small Angle X-ray Scattering，SAXS）数据。本次实验所用X射线束能量为5.5 keV，光束通过近场钨孔径（厚度12微米，外径7.5微米）进行限束。样品为厚度20微米的胶体玻璃薄层，由二氧化硅（SiO₂）微球（外径300纳米）构成，夹于两层Kapton薄膜之间，其中一层Kapton薄膜用作20微米厚的间隔层。 本归档文件包含以下内容： - 针对陈化2天与20天的胶体玻璃以及压缩前后的样品，采集的时空扫描微型小角X射线散射（micro-SAXS）衍射图案（分辨率256×256，格式为.tif）并已完成裁剪。 - 陈化后的胶体玻璃采用2微米的空间步长进行扫描，扫描时间间隔为1040秒；压缩前后的形变扫描则采用4微米的空间步长，扫描时间间隔为2250秒。文件命名遵循`dp_t_x_y.tif`的规范，其中`t`代表时间步，`x`与`y`分别对应x、y方向的空间步长。 - 所有扫描区域均选取玻璃厚度均匀且无可见纤维、灰尘等杂质的位置。
