First observations of dispersive shock waves from the KdV equation in an electron beam

Abstract: We present the first experimental observation of dispersive shock waves (DSWs) in an electron beam. Using the University of Maryland Electron Ring (UMER), a 10 keV electron beam was perturbed with a localized beam velocity dip. The resulting current profiles evolve into oscillatory structures consistent with dispersive shock behavior governed by the Korteweg–de Vries (KdV) equation. These results are predicted by particle-in-cell simulations using the WARP code. The observed dynamics open new avenues for studying nonlinear longitudinal phenomena in intense beam systems.
