ABSTRACT
A high-temperature magnetized plasma such as exists in modern magnetic fusion experiments is one of the most complex media in existence. Although adequately described by classical physics (augmented with atomic and nuclear physics as required to describe the possible interaction with neutral atoms and the energy release due to nuclear reactions), the wide range of time scales and space scales present in the most general mathematical description of plasmas make meaningful numerical simulations which span these scales enormously difficult. This is the motivation for deriving and solving reduced systems of equations that purport to describe plasma phenomena over restricted ranges of time and space scales, but are more amenable to numerical solution.
