Journal ArticleDOI
Near-GeV Acceleration of Electrons by a Nonlinear Plasma Wave Driven by a Self-Guided Laser Pulse
Stefan Kneip,S. R. Nagel,S F Martins,Stuart Mangles,C. Bellei,Oleg Chekhlov,R. J. Clarke,Nicolas Delerue,E. J. Divall,G. Doucas,Klaus Ertel,Frederico Fiuza,Ricardo Fonseca,Peta Foster,S. J. Hawkes,C.

TL;DR: Three-dimensional particle in cell simulations show that the intensity within the guided filament is amplified beyond its initial focused value to a normalized vector potential of a0>6, thus driving a highly nonlinear plasma wave.

TL;DR: In this article, the authors showed that the heating is maximized close to the wire surface, by comparison of interferometric measurements with hydrodynamic simulations, including a reversal of the magnetic field on the inside of the wire.
