ILL, CRISP workshop, 17th marsh 2014 Neutron Imaging in research and Industry Yves Bréchet HC Atomic Energy
Assets (1) • Grenoble speciality ( both neutrons and X rays large instruments) • Direct space direct interpretation direct artefacts • Mesoscale: 10 m m and above Natural scales Man made structures Scale of damage events
Asset (2) • Deep penetration Non destructive analysis Long range interation phenomena ( elastic stresses) • Sensitive to light elements
Who may be interested? • Anybody interested in the elements with the largest cross section such as Li, H2, Cl… Fuel cells , batteries… • Any body with events at the mesoscale =>cracks, voids, methanisation … • Anybody interested in fuid motion in situ => microfluidics, heat exchangers

If you could go to a better resolution … around 1 m m • Cavity nucleation in creep • Hydrides formation under stress in Zr • Fluid flow and boiling crisis • Cavitation process in diesel • Foamings of polymers and metals • Non destructive testing of glued assemblies • Distribution or organic and inorganic matter in structural biomaterials • …
