提出了一种用于获取粉末 X 射线衍射数据的新颖几何结构,称为焦点构造几何结构 (FCG)。由于采用了空心管束布置,FCG 获得的衍射数据已被证明具有显着增强的强度。与传统衍射相反,探测器被平移以沿主轴收集图像并记录布拉格最大值的位置。这些高强度凝聚焦点是 FCG 所独有的,是由于德拜锥体在主轴上的单个点处会聚而出现的。这项工作重点关注二维基本参数方法来模拟实验数据并随后帮助解释。这种卷积方法被证明可以很好地再现实验衍射图,并且在某些情况下还可以适应择优取向效应。
A novel geometry for the acquisition of powder X-ray diffraction data, referred to as focal construct geometry (FCG), is presented. Diffraction data obtained by FCG have been shown to possess significantly enhanced intensity due to the hollow tube beam arrangement utilized. In contrast to conventional diffraction, the detector is translated to collect images along a primary axis and record the location of Bragg maxima. These high intensity condensation foci are unique to FCG and appear due to the convergence of Debye cones at single points on the primary axis. This work focuses on a two dimensional, fundamental parameter's approach to simulate experimental data and subsequently aid with interpretation. This convolution method is shown to favorably reproduce the experimental diffractograms and can also accommodate preferred orientation effects in some circumstances.
