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
Electron acceleration from the breaking of relativistic plasma waves
A. Modena,Zulfikar Najmudin,A. E. Dangor,C. E. Clayton,K. A. Marsh,C. Joshi,Victor Malka,Christopher B. Darrow,Colin N. Danson,David Neely,F. N. Walsh +10 more
TL;DR: In this article, the authors report observations of relativistic plasma waves driven to breaking point by the Raman forward-scattering instability induced by short, high-intensity laser pulses.
Journal ArticleDOI
Collisionless shocks in laser-produced plasma generate monoenergetic high-energy proton beams
Dan Haberberger,Sergei Tochitsky,Frederico Fiuza,Chao Gong,Ricardo Fonseca,Ricardo Fonseca,Luis O. Silva,Warren Mori,C. Joshi +8 more
TL;DR: Discovery of a laser–plasma acceleration mechanism that generates 20 MeV proton beams with a 1% spread is a promising step in the development of laser-driven proton accelerators.
Journal ArticleDOI
Self-Guided Laser Wakefield Acceleration beyond 1 GeV Using Ionization-Induced Injection
C. E. Clayton,Joseph Ralph,Felicie Albert,Ricardo Fonseca,Siegfried Glenzer,C. Joshi,Wei Lu,K. A. Marsh,Samuel Martins,Warren Mori,Art Pak,Frank Tsung,B. B. Pollock,B. B. Pollock,Jason Ross,Jason Ross,Luis O. Silva,Dustin Froula +17 more
TL;DR: Computer simulations confirm that it is the K-shell electrons of oxygen that are ionized and injected into the wake and accelerated to beyond 1 GeV energy.
Journal ArticleDOI
Ultrahigh-gradient acceleration of injected electrons by laser-excited relativistic electron plasma waves
TL;DR: High-gradient acceleration of externally injected 2.1-MeV electrons by a laser beat wave driven relativistic plasma wave has been demonstrated for the first time.
