KurzbeschreibungThe 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. The students will also acquire hands-on experience by designing and performing an experiment in a large scale facility of PSI (Swiss Light Source, Swiss Spallation Neutron Source, Swiss Muon Source).
LernzielThe course runs for two weeks in a row in September before the regular semester lectures start. It takes place at the campus of the Paul Scherrer Institute. The first week consists of introductory lectures on the use of photons, neutrons and muons for materials characterization. Active participation of the students in the form of workgroups aimed at learning the basic concepts is also part of the first week program. The second week is focused on hand-on experiments on specific topics. The topical section includes tutorials and one to two experiments designed and performed by the students at one of the large scale facilities of PSI (Swiss Light Source, Swiss Spallation Neutron Source, Swiss Muon Source).
