STUDIES OF THE NONLINEAR PHYSICS OF ALFVEN WAVES IN THE LARGE PLASMA DEVICE| Session Chairs: | Ashild Fredriksen, Erik Tejero |
The plasma environments surrounding the Earth and other solar system bodies display a rich variety of phenomena, which can now be observed with unprecedented spatial and temporal resolution by modern space probes and ground-based observatories. These plasmas consist of thermal and energetic particle populations, a variety of ion and neutral species, and also charged particulate matter, which can influence the dynamics of the system. While high-resolution observations can provide tantalizing snapshots of events and statistical overviews of dynamical behavior, repeatable experiments under strictly controlled conditions are not possible in space. Laboratory experiments can provide useful insight in space phenomena by investigating the underlying physics under appropriately scaled, controlled plasma conditions. Among these are experimental studies of wave propagation characteristics, wave-particle interactions, nonlinear dynamics and instabilities, dusty plasma dynamics, double layer and beam formation, development of plasma thrusters, and plasma astrophysics. Papers on basic and applied laboratory studies addressing such space processes are solicited.
