Waves and Instabilities in Steady-State High-Beta Plasmas.

Abstract

Stimulated Brillouin scattering has been conclusively identified in a microwave simulation experiment. The threshold and initial growth rate are in agreement with the convective finite interaction length theory. Saturation of the SBS ion waves and associated backscattered electromagnetic wave are observed and a tentative identification of ion trapping as the saturation mechanism has been made. Observations of spontaneous magnetic field generation at low power continued in an attempt to conclusively identify the saturation mechanism. The soliton flash has been studied together with the associated phenomena such as hot electron production, spontaneous magnetic field generation and ion wave instabilities. The finite beta waves and instabilities effort has also continued with primary emphasis on large diameter, high density plasma production. (Author)
