Plasma Wave Observations During Electron Beam Experiments at High Altitudes
Abstract
Electron beam experiments on the nearly geosynchronous P78-2 satellite conducted in 1979 resulted in observations of electron distributions suggestive of electron heating. Plasma wave observations during these experiments indicated intense radiation at the local electron gyrofrequency. The amplitude of these waves depended upon beam parameters. During 50 eV beam operations, current levels of 10 microAmps produced strong emissions. Current levels of 1 microAmps and 100 microAmps did not. Sufficient power was in the observed emissions to explain the heated electron distributions observed during the experiments. (jhd)
