应用框架存储型pn结CCD探测器对γ-LiAlO2晶体进行了白光同步辐射的能量色散x射线劳埃衍射研究。利用探测器的同时空间和能量分辨率，可以在没有任何先验信息的情况下确定γ-LiAlO2的晶体单位胞。通过将单次曝光下的实验结构因子与已知晶体结构的计算结果进行比较，测试了该方法在x射线结构分析中的应用潜力。利用角相关参数和能量相关参数对实测光斑强度进行校正后，实验结果与理论运动学结构因子的一致性优于10%。
A frame-store pn-junction CCD detector was applied to the energy-dispersive X-ray Laue diffraction study of a γ-LiAlO2 crystal with white synchrotron radiation. Exploiting the simultaneous spatial and energy resolution of the detector the crystallographic unit cell of γ-LiAlO2 could be determined without any a priori information about the sample. The potential for application in X-ray structure analysis is tested by comparing experimental structure factors taken under a single exposure with those calculated from the known crystal structure. After correcting the measured spot intensities by angular and energy-dependent parameters, the agreement between experimental and theoretical kinematical structure factors is better than 10%.
