Journal ArticleDOI
Generating multi-GeV electron bunches using single stage laser wakefield acceleration in a 3D nonlinear regime
Wei Lu,Michail Tzoufras,C. Joshi,Frank Tsung,Warren Mori,Jorge Vieira,Ricardo Fonseca,Luis O. Silva +7 more
TL;DR: In this article, a phenomenological framework for laser wakefield acceleration (LWFA) in the 3D nonlinear regime was developed, in which the plasma electrons are expelled by the radiation pressure of a short pulse laser, leading to nearly complete blowout.
Journal ArticleDOI
Generation of neutral and high-density electron-positron pair plasmas in the laboratory
Gianluca Sarri,Kristjan Poder,Jason Cole,William Schumaker,A. Di Piazza,Brian Reville,Thomas Dzelzainis,Domenico Doria,Leonida A. Gizzi,G. Grittani,Satyabrata Kar,Christoph H. Keitel,Karl Krushelnick,S. Kuschel,Stuart Mangles,Zulfikar Najmudin,Nitin Shukla,Luis O. Silva,Dan Symes,Alexander Thomas,M. Vargas,Jorge Vieira,Matthew Zepf +22 more
TL;DR: It is shown that, by using a compact laser-driven setup, ion-free electron–positron plasmas with unique characteristics can be produced, and their charge neutrality, high-density and small divergence finally open up the possibility of studying electron– Positron Plasmas in controlled laboratory experiments.
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. J. Hooker,Karl Krushelnick,Warren Mori,Charlotte Palmer,K. Ta Phuoc,P. P. Rajeev,Jörg Schreiber,M. J. V. Streeter,D Urner,Jorge Vieira,Luis O. Silva,Zulfikar Najmudin +26 more
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.
Journal ArticleDOI
Beam Loading in the Nonlinear Regime of Plasma-Based Acceleration
Michail Tzoufras,Wei Lu,Frank Tsung,Chengkun Huang,Warren Mori,Tom Katsouleas,Jorge Vieira,Ricardo Fonseca,Luis O. Silva +8 more
TL;DR: A theory that describes how to load negative charge into a nonlinear, three-dimensional plasma wakefield is presented and it is shown that very high beam-loading efficiency can be achieved, while the energy spread of the bunch is conserved.

TL;DR: Measurements of electrons accelerated up to two gigaelectronvolts at the AWAKE experiment are presented, in a demonstration of proton-driven plasma wakefield acceleration and are an important step towards the development of future high-energy particle accelerators.
