The continuous wavelength spectrum available at pulsed neutron sources and the use of a position sensitive detector can drastically reduce the number of sample orientations during pole figure scanning compared to the conventional method using monochromatic neutrons. This advantage has to be paid for by a more complex way in extracting pole figures from the measured data. The paper describes the experimental setup, the scanning procedure and the data evaluation of neutron diffraction texture measurements at a spallation source. A multitude of individual pole figures can be measured simultaneously within a reasonable time. The paper focuses on strategy and practical management to obtain pole figures from two-dimensional time-of-flight diffraction patterns.
