Factors affecting count rate in a neutron strain scanning experiment. (a) Integrated count rate for selected peaks of powders of common structural materials. The count rate is for a 1 mm3 gauge volume 1 mm under the surface of the specimen. The solid symbols correspond to experiments performed on the ENGIN-X instrument. The lines are the values predicted by equation (11)[link]. The experimental uncertainty is smaller than the symbols. (b) Attenuation of the beam as a function of the neutron path inside the specimen. The graph shows the integrated peak intensity for selected reflections. The lines are least-squares fits to the data using an exponential decay law. (c) Measured and simulated count rates for a line scan across a 25 mm cube filled with iron powder.
