PLASMA OSCILLATIONS AND PARTICLE TRAJECTORIES IN A DRIFTING ELECTRON STREAM; PALMER DIAGRAMS

Abstract

Electron trajectories are obtained for the Hahn-Ramo space-charge waves. The approach is to use Lagrangian form of hydrodynamic equations of motion and of continuity. This is in contrast with the more common Eulerian jelliedout fluid approach where the particle identity is lost. The model used is developed in some detail. Trajectory plots are given for the faster and slower space-charge waves by themselves and for velocity modulation for the ratios of driving frequency to selected plasma frequencies.
