Neutron imaging in materials research

Orateur : Nikolay KARDJILOV (Helmholtz-Zentrum Berlin für Materialien und Energie - Germany)

The material characterization by neutron imaging reached a new level after developing innovative techniques using different contrast mechanisms than the common beam attenuation. In this way properties of materials and complex systems can be resolved by position sensitive mapping of diffraction, small-angle scattering and refraction signals. The unique nature of neutron radiation allows for high sensitivity to light elements, distinctive penetration depth in metals and susceptibility to magnetic fields. Applications related to 2D and 3D visualization of material phase heterogeneities, texture, fluid dynamics, magnetic structures and phase transitions in applied materials will be presented.
