Abstract

Anomalous heating of a plasma by an electric field oscillating near the plasma frequency is considered. The large field excites the oscillating two-stream and the ion-acoustic decay instabilities. Numerical simulation of these instabilities has confirmed the linear theory for their growth and has shown that when the instabilities saturate a strong anomalous heating occurs. This heating results in the production of energetic electrons. A simple nonlinear theory gives results in reasonable agreement with the numerical calculations. These predictions could be applied to laboratory experiments.

    E. Valeo and C. Oberman have a systematic kinetic theory treatment of this problem for pump fields near threshold and for Te ~ few Ti. They then find that scattering of the unstable plasma oscillations by ion fluctuations is the dominant physical process for the saturation of the instability (private communication).Google Scholar
