| Abstract Scope |
Neutron diffraction provides information on the crystal structure (nanometer length scale) and micro-structure (micrometer length scale) of a material averaged over the entire probed volume of ~1 ccm. Energy-resolved neutron imaging (ERNI) on the other hand provides information on the spatial distribution of attenuation (sample thickness, concentration of hydrogen or absorbing elements etc.) with a resolution of up to ~10 micrometers. Tomographic methods applied to these techniques provide 3D maps of isotopes or microstructural features such as phase fraction from Bragg-edge radiography & tomography (BERT). In January 2024, the HIPPO beamline was upgraded with a LoskoVision TimePix camera to view the nominally 10 mm diameter beam spot. We present the setup and first results of experiments on nuclear fuels, additively manufactured dissimilar welds, steels solidified in microgravity (parabolic flight) as well as hypergravity (centrifugically cast), and minerals.
