Synopsis:

This subject is focused on physics and technology of magnetic pinches which represent the most efficient way how to generate high-energy density plasmas (>100 kJ/cm3). The lectures will introduce students into the basic theory, contemporary research topics, and applications of magnetic pinches. One of the objectives of the subject is to demonstrate that the pinch effect naturally occurs in laboratory and space plasmas and has an impact on many applications. The subject “Magnetic pinches”, therefore, contributes to a better understanding of fundamental processes in plasmas.
