FOR 1048 PostGraduate School
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.
