The course "Key Concepts of Experimental Physics" (3 double periods of lectures + 1 double period tutorial) is part of the module "Phy-Ma-Exp" of the Master of Physics course. The lectures and tutorials will present experimental methods and concepts for analysing and understanding structures and excitations of physical systems. In particular, strategies and ideas will be discussed which are common to different fields of physics, like atomic physics, molecular physics, solid state physics, particle and nuclear physics, etc. This will help to establish new connections and provide a deeper understanding of different domains of physics.
