Electron Plasma Oscillations Associated with Type III Radio Emissions and Solar Electrons.
Abstract
An extensive study of the IMP-6 and IMP-8 plasma and radio wave data has been performed to try to find electron plasma oscillations associated with type III radio noise bursts and low-energy solar electrons. This study shows that electron plasma oscillations are seldom observed in association with solar electron events and type III radio bursts at 1.0 AU. In nearly four years of observations only one event was found in which electron plasma oscillations are clearly associated with solar electrons. For this event the plasma oscillations appeared coincident with the development of a secondary maximum in the electron velocity distribution functions due to solar electrons streaming outwards from the sun. Numerous cases were found in which no electron plasma oscillations with field strengths greater than 1 microV/m could be detected even though electrons from the solar flare were clearly detected at the spacecraft.
