Energy-dispersive Laue diffraction by means of a frame-store pnCCD

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%.
