Book Description
The objective of this research was to find experimental evidence of an 'anomalous' resistance in plasmas. Anomalous resistance results when collective action by electrons causes randomization of the growing oscillations in the two-stream instability. This sequence of events leading to dissipation of energy was predicted several years ago by Buneman. It is believed that this objective was achieved (i.e., that anomalous resistance is evidenced by observations to be reported here), on a high density plasma subjected to r-f fields by a cavity resonant at a frequency well below the plasma frequency. With sufficient r-f power and density, the two-stream instability should be excited to turbulence level during each halfcycle, causing irreversible power loss. Calculations enumerating the necessary conditions for observing the phenomena were made, showing that the resistance can easily be seen above the intrinsic cavity loss using very moderate amounts of power.

Collective Phenomena in Plasmas and Elsewhere
Author: Kamel Ourabah
Publisher: John Wiley & Sons
ISBN: 1786307693
Category : Science
Languages : en
Pages : 196
Book Description
The Universe is made up of systems consisting of a very large number of particles interacting in a very complex way. When studying these systems, a precise microscopic approach is unattainable. In practice, the best strategy is one that is able to “distinguish” between superfluous information and the information needed to make predictions about the evolution of the system. There are two main competing approaches: kinetic and hydrodynamic. Collective Phenomena in Plasmas and Elsewhere presents an overview of the theoretical bases of these kinetic and hydrodynamic approaches, but also discusses their limitations, the links between them and their extension to quantum mechanics and relativity. These methods were born in part out of the study of plasmas, but they also have more universal applications. A general framework for these approaches is outlined, followed by some applications in plasmas, gravitation, Bose–Einstein condensates and dark matter. Particular emphasis is placed on the analogies that can be made between all these different systems.
