Course objectives

Learning the basic principles of neutron-matter interaction, and how to exploit them to study matter.
Learn the principles of neutron imaging (radiography and tomography and be able to evaluate the possible use of this technique to characterize materials
Learn the principle of time of flight neutron diffraction and the Rietveld method for quantitative phase analysis, residual stress analysis and microstructural characterization of crystalline materials.

Program

Thermal and cold neutron-matter interaction, elastic scattering law, cross section. (1 hr)

Principles of neutron production, concept of neutron beamlines (1 hr)

Neutron imaging, Lambert beer law, attenuation law, neutron geometry and optics, example of beamlines, data analysis (radiography and tomography) (3 hrs)

Neutron diffraction, Bragg law, scattering law, basics of crystallography, neutron instrument geometry and parameters, data analysis (Rietveld refinement using GSAS code) (3 hrs)
