Micro-SAXS colloidal glasses March 2014

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)本归档文件包含2014年3月由Amelia Liu、Martin de Jonge、Stephen Mudie、Tim Petersen与Rico Tabor在澳大利亚同步辐射装置的小角/广角X射线散射（SAXS/WAXS）光束线采集的小角X射线散射（SAXS）数据。实验采用的X射线光束能量为5 keV，光束通过一对锗（Ge）狭缝限定以限制发散，并借助近场钨孔径（外径20微米）完成束流整形。实验样品为厚度20微米的胶体玻璃薄层，由二氧化硅（SiO₂）微球（外径300 nm）构成，夹在两层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： 1. 原始微区SAXS空间扫描数据：以5微米步长完成61×61步扫描，数据存储于压缩文件夹内的.tif格式文件中； 2. 胶体玻璃的结构因子与径向分布函数（S(q)与g(r)），存储为.csv格式文件； 3. 基于微区SAXS图案结构因子第一峰，通过角自相关函数推导得到的平均方位对称性数据（相关方法参见ACY Liu等人2013年发表于《物理评论快报》（PRL 110, 205505, 2013）及2016年发表于《物理评论快报》（PRL 116, 205501, 2016）的研究成果）。该数据存储为.txt格式，包含字段依次为：幅值、标准差、标准误、系统误差、总误差（随机误差与系统误差之和）。其中标记为"Even"的数据表示依据ACY Liu等人2015年发表于《晶体学报A辑》（Acta Cryst A 71, 473-482, 2015）所述方法，针对动力学衍射效应完成校正后的对称性幅值； 4. 用于分解胶体玻璃对称性的典型原型团簇的旋转平均投影对称性数据，存储为.txt格式文件。
