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.
