Excitation of Large Amplitude Plasma Waves by Runaway Electrons.
Abstract
A relativistic computer simulation demonstrates that the application of a DC electric field enhances the excitation of plasma waves through runaway electrons. The presence of an elongated tail in the distribution function gives rise to acoustic-type modes which interact strongly with the runaway population. The waves produce a strong drag which reduces the runaway momentum increase from 2/3 to 1/2 of the free fall value. A threshold DC electric field is found above which there is no collective slowdown.
