Nonlinear Dynamics of Electron Cyclotron Heated Plasmas
Plasmas that are generated and sustained by electron cyclotron heating (ECH) have been studies experimentally and theoretically for more than thirty years. Even so, many of the fundamental processes that govern the properties of ECH plasmas are strongly nonlinear and are still only poorly understood. In what follows we identify four distinct types of nonlinear dynamical processes that have important consequences for ECH plasmas, briefly describe their effects on the observed properties of the plasmas, and indicate the approaches that have been used to analyze them.
