New pole figure calculation software: 2DiffCalc

At neutron and synchrotron radiation research facilities, texture measurement with area detectors leads to a large amount of data. During the measurement time, a preliminary analysis of the acquired diffraction patterns is essential. A first view of the resulting pole figures affords the opportunity to evaluate the measurement and to change the instrument parameters accordingly. At a large research facility, the instrument is built with unique adaptations to different scientific cases. At this stage, there is no commercial standard software available to analyse the measured raw data. For these purposes, new software, 2DiffCalc, was developed to provide a fast method for pole figure calculation. This software is able to determine the pole figure intensities automatically from the measured area-detector images. 2DiffCalc calculates the integral intensities, peak position and width in combination with the pole figure angles.
