title: Determination and mitigation of the uncertainty of neutron diffraction measurements of residual strain in large-grained polycrystalline material.
abstract: For large-grained samples it is advantageous to perform pairs of neutron diffraction measurements at the same spatial location but rotated 180° around the geometric centre of the gauge volume as a means of minimizing the scatter coming from the random positioning of grains within the gauge volume.
