Abstract:

The report discusses the progress which has been made tward the research goal of understanding the development and nature of turbulence generated from a source of free streaming energy within a collisionless plasma. The initial evolution of microturbulence, during which the electron drift energy is very efficiently converted to electron thermal energy and ion sloshing energy, is now largely understood. The authors have also developed a model of the late-time turbulence evolving in a driven toroidal confinement device. Several investigations have also been completed of the generation of plasma turbulence via the decay of large amplitude waves. Finally, the authors have initiated research on the feasibility of heating fusion plasmas via the injection of energetic beams of relativistic electrons. Author
