The open access version of the article is available in the journal on Nuclear Instruments & Methods in Physics Research. The study reports the development of a standardised approach for quantitative analysis of positional accuracy on neutron strain scanners.
Positional accuracy is an important parameter in residual stress investigations with neutron diffraction, considering that precise measurements of strains at the same localised position along a number of sample orientations are required, including investigations of complete complex shaped engineering components.
The standardised approach confirms the high positional precision attainable for non-destructive stress determination, to benefit academia and industry alike. It is envisaged that the common calibration protocol and reporting template conforms to the newly developed Neutron Quality Label for Internal Stress Characterisation be adopted by other facilities to facilitate expansion of the supportive network.
