AbstractThe main aim of the course is to enable the students to independently choose a suitable material characterization methods to address a specific materials science question. Subject areas are: light microscopy, diffraction methods (X-rays, neutrons, electrons), electron microscopy, atom probe tomography and atomic force microscopy. Depending on lecturer, lectures and practicals in German or English.
Objective- Being able to explain the fundamentals of basic and advanced materials characterization methods based on microscopy and diffraction modalities.

- Being able to identify and solve practical problems of selected characterization methods based on corresponding laboratory work.

- Being able to advice non-experts why, how and when these methods can be used to assess what type of information, and to draw awareness to possible problems and limitations of these methods.
ContentIn the first part of the semester, different lecturers will present the fundamentals of the materials characterization methods mentioned above. This is the lecture part of the course. In the second half of the semester, the students, grouped in teams, will apply selected methods. These laboratory works are at the heart of the course, where the students are faced with practical problems and the limitations of the different methods, and where they have to independently elaborate solutions within the teams. Special: some practical courses are offered at the Paul Scherrer Institute, where the students can make use of the neutron and synchrotron X-ray facilities. These courses will take place after the end of the semester and occupy half and full days.
Lecture notes- Slides of the lectures (in English) will be distributed electronically.
- Depending on the laboratory course, additional documentation will be made available.
- In laboratory journals, the students are asked to compose their own documentation of the laboratory courses.

327-2130-00LIntroducing Photons, Neutrons and Muons for Materials Characterisation Restricted registration - show details 2 credits3GA. Hrabec
AbstractThe course takes place at the campus of the Paul Scherrer Institute. The program consists of introductory lectures on the use of photons, neutrons and muons for materials characterization, as well as tours of the large scale facilities of PSI.
ObjectiveThe aim of the course is that the students acquire a basic understanding on the interaction of photons, neutrons and muons with matter and how one can use these as tools to solve specific problems.
ContentThe course runs for one week in June (19th to 23rd). It takes place at the campus of the Paul Scherrer Institute. The morning consists of introductory lectures on the use of photons, neutrons and muons for materials characterization. In the afternoon tours of the large scale facilities of PSI (Swiss Light Source, Swiss Spallation Neutron Source, Swiss Muon Source, Swiss Free Electron Laser), are foreseen, as well as in-depth visits to some of the instruments. At the end of the week, the students are required to give an oral presentation about a scientific topic involving the techniques discussed. Time for the presentation preparations will be allocated in the afternoon.

• Interaction of photons, neutrons and muons with matter
• Production of photons, neutrons and muons
• Experimental setups: optics and detectors
• Crystal symmetry, Bragg’s law, reciprocal lattice, structure factors
• Elastic and inelastic scattering with neutrons and photons
• X-ray absorption spectroscopy, x-ray magnetic circular dichroism
• Polarized neutron scattering for the study of magnetic materials
• Imaging techniques using x-rays and neutrons
• Introduction to muon spin rotation
• Applications of muon spin rotation
Lecture notesSlides from the lectures will be available on the internet prior to the lectures.
