A diffraction geometry utilizing convergent X-rays from a polycapillary optic incident on a stationary crystal is described. A mathematical simulation of the resulting diffraction pattern (in terms of spot shape, position and intensity) is presented along with preliminary experimental results recorded from a lysozyme crystal. The effective source coverage factor is introduced to bring the reflection intensities onto the same scale. The feasibility of its application to macromolecular crystal data collection is discussed.
描述了一种衍射几何结构，该结构利用来自多毛细管光学元件的会聚X射线入射到固定晶体上。给出了所得衍射图样（光斑形状、位置和强度方面）的数学模拟以及从溶菌酶晶体记录的初步实验结果。引入有效源覆盖因子以使反射强度处于同一尺度。讨论了其应用于大分子晶体数据收集的可行性。
