Runaway Electrons in Collective Electric Fields.
Abstract
The interactions of runaway electrons with the anomalous-Doppler shifted mode and a bump-on-tail mode are studied numerically using the Fokker-Planck equation with a self-consistent quasilinear diffusion operator. The resulting frequency spectrum and the synchrotron radiation power agree with the experimental observations. Furthermore it is shown that there is a velocity threshold, below which electrons are not pitch-angle scattered by the self-consistent electric fields. The observed long-time behavior of synchrotron radiation data implies that this velocity threshold must shift to higher velocity as an experiment progresses.
