| Abstract: | The effect of a large amplitude Langmuir wave on the Weibel instability in a plasma with an electron beam is studied.The electromagnetic perturbation couples to the Langmuir wave to give rise to two Langmuir sideband waves, which in turn produce a current enhancing the electromagnetic perturbation. The Langmuir wave enhances the growth over its linear value.
The enhancement is larger at shorter wavelengths. For uO/c N 0.15, the growth rate is enhanced by a factor of 3/2. |
