Course contents :
|
| An introduction will present the essential concepts of the operation of radiation sources and the characteristics of the interaction between the radiation and matter. The application fields, the type of information that can be accessed, and the length and energy scales that are accessible will be presented in relationship with other techniques (infrared spectroscopy, Raman scattering, visible light and electron microscopy, NMR, dynamic light scattering, ...). For the structural aspects, the similarities and difference of x-ray and neutron diffraction will then be discussed, in terms of contrast, form factor, incoherent scattering, and polarisation analysis. The total scattering technique and the pair distribution function for the investigation of non crystalline systems as well as the small angle scattering techniques for the investigation of nanostructures will complement this part. The techniques that yield access to the dynamics and diffusion phenomena will then be broached. Applications will cover solid state physics (lattice vibrations), polymer dynamics, ionic diffusion, and vibrational spectroscopy of molecules and proteins. Imaging and tomographic techniques using x-rays and neutrons will be discussed next, as well as some specialised analytical methods (EXAFS, X-ray fluorescence, nuclear resonance scattering, prompt gamma activation analysis). For all the discussed techniques the specificity of the instruments will be covered. Finally the management of a successful experiment, from the planning until the report will be discussed in order to prepare the students to use large scale facilities in their future career. |
|
Learning outcomes of the course :
|
| As outcome of this learning, the student will be able to understand and communicate the basic concepts of the large scale facilities and their specificity in the caracterisation of materials be able to write a proposal and carry out the planning of an experiment. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| Bachelor diploma in chemistry, physics or biology.
Basics in cristallography and the electronic structure of the atom. |
|
Planned learning activities and teaching methods :
|
| Exercice sessions during the course.
A (2 d.) visit to a radiation source. |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| Face-to-face teaching. The schedule will be fixed at the beginning of the academic year 14-15 by the Department of Chemistry. |
