Motivation

Magnetic fields are known to play important roles in astrophysical systems on all scales and in all environments, from the star formation process and stellar flares, to compact objects and the heliosphere, and from large-scale magnetic fields in galaxies to clusters of galaxies. Key questions in astrophysics today are directly linked to magnetic fields such as the collimated outflows in jets, which are most likely responsible for the acceleation of the most energetic particles in the Universe. Given this omnipresence and the importance for the most energetic processes it is very surprising to see how little is known about the generation of the observed cosmic magnetic fields and their turbulence. Crucial in our understanding of the observed properties is the dynamo process, the most likely mechanism considered viable to generate and maintain the observed magnetic field properties. However, the detailed physics of this non-linear process is not well understood either. An understanding of "real" dynamos is meanwhile considered a fundamental problem in physics. Therefore, several laboratory experiments have been designed to study the process in more detail. This school tries to cover all these different aspects in a series of introductory lectures. Complementary first-hand information on special topics will be given by experts in the field. A general introduction to plasma physics will be followed by lectures on experiments and theory of MHD dynamos as well as the structure and turbulence of magnetic fields covering scales from laboratories to galaxies. The school is directed at PhD students and postdoctoral researchers in plasma- and astrophysics.
