 | The main effort was to understand the physics of a very energetic ion beam propagating through a magnetized plasma roughly perpendicular to the magnetic field. It has been appreciated for several years that the central problem is the charge neutralization of this beam. For conditions where ion beam number density is comparable or larger than plasma number density, the motion of the electrons is quite complicated being controlled by the ... |

|
| During this report period research was conducted in the following areas: (1) The study of the plasma state of matter, with particular emphasis on its nonlinear collective effects; and (2) The application of knowledge gained of the plasma state to the interpretation of various dynamic phenomena in which collective effects play a role such as anomalous transport phenomena, nonlinear wave absorption, and plasma-wave turbulence, both in the laboratory and in ... |

|
| The development of a technique in nonlinear plasma theory powerful enough to determine the saturation level of many important plasma instabilities was explored. This work applies understanding to electron thermal transport in tokamak plasmas, convection cells in uniform magnetic fields, magnetic field breakup by drift waves, and the stochastic behavior of particles in the associated microfield structure. In studying magnetic reconnection near x points, it appears that the tearing mode ... |

|
| Attention is focused on the resonant interaction between a single charge, treated relativistically, and two coherent electromagnetic waves. The simplicity of context is exploited to elucidate aspects of the nonlinear theory of induced Compton scattering. In this paper I, a well-defined problem of finite duration is studied, namely the induced scattering of plane radiation pulses of arbitrary shape. The factors which affect the net wave conversion from one pulse to ... |

|
| Work on the importance of parametric instabilities for modification of the ionosphere by strong radio wave heating was continued under this contract. The saturation mechanism for the amplitude of these instabilities was determined. A new mechanism for wave-wave coupling was discovered and invoked to explain the many field-aligned plasma density striation phenomena which occurred in the ionospheric heating experiments. |

|
| The discovery and elucidation of parametric instabilities and their application to the modification of the ionosphere by intense radar beams was pursued under this contract. The theory of their linear growth was developed and their nonlinear saturation mechanism worked out. Research was done on the nonlinear results of these instabilities and their application to other areas such as laser heating of pellets. The general mathematical theory underlying nonlinear phenomena continued ... |
