Industrial use of NIAG beamlinesNeutron imaging as a non-destructive testing method can be used for a broad spectrum of industrial applications. It provides similar capabilities as industrial X-ray i.e. radiographic images or 3D tomographic views of samples with a size of a few centimeters up to tens of centimeters. Due to the quite different attenuation characteristics of neutrons and X-ray, neutrons are most useful if small amounts of hydrogenous material has to be detected within a metallic or ceramics sample.
Examples of industrial projects
A: Outside view, B: Brazing material distribution
C: Semi-transparent rendering, D: Orthogonal cut through sample
Neutron tomography is presently the only possibility to obtain information about the three-dimensional distribution of soot and ash in a filter monolith. The estimation of the soot distribution in a diesel particulate filter with neutron imaging is possible because neutrons are highly sensitive to the element hydrogen, which is content of soot.
Boron containing brazing solder shows with high contrast in a steel sample. This is due to the high neutron absorption coefficient of boron for thermal neutrons.
