It is well known that the neutron diffraction is suitable to evaluate the crystallographic textures of various bulk materials while the measured texture results are partially dependent on the diffractometer used. Since JAEA has several neutron diffractometers for texture measurement, including RESA, RESA-II and MUSASI (JAEA), the quantitative comparison among bulk textures of several selected samples is helpful to further optimize the measurement conditions and ensure the users to get reliable results. By proper selection of neutron beam size and collimator size, the evaluation reliability of MUSASI was improved so that it may be utilized to reliably measure neutron textures of various materials.
