Abstract
Relativistic particle simulations of the beam-plasma interaction show that a dc electric field intensifies the interaction and amplifies radiation; radiation in turn clamps the runaway momentum. When the dc field exceeds a critical value, the runaways are detached from collective interactions. The effect of enhanced radiation and clamping may be of significance for devices such as traveling-wave tubes and free-electron lasers and for tokamak experiments.Keywords
