Abstract

The dependence of a peak diffraction angle on the positioning of the diffracted-beam Soller-slit pack was observed and studied by discussing the determining factors. In particular, the misalignment angle between the Soller pack and the counter axis is recognized as a key factor and experiments were performed for giving a quantitative basis to this statement. An important consequence of the results of these experiments and related profile analysis is the suggestion of designing parallel-beam diffractometers with the possibility of checking and changing the position of the diffracted-beam Soller-slit packs in order to optimize the performance of the instrument.
