Christopher I. Moore,Antonio Ting,Karl Krushelnick,Eric Esarey,Richard F. Hubbard,Bahman Hafizi,H. R. Burris,Charles Manka,Phillip Sprangle +8 more
TL;DR: In this paper, a self-modulated laser wakefield accelerator was used to accelerate 10 electrons to energies greater than 1 MeV with a peak energy of approximately 30 MeV.
Journal ArticleDOI
A Laser-Accelerator Injector Based on Laser Ionization and Ponderomotive Acceleration of Electrons
TL;DR: In this paper, a new laser-accelerator injector based on the high-energy electrons ejected from a laser focus following the ionization of high-charge states of gases has been investigated.
Journal ArticleDOI
Wakefield generation and GeV acceleration in tapered plasma channels.
Phillip Sprangle,Bahman Hafizi,J. R. Peñano,Richard F. Hubbard,Antonio Ting,Christopher I. Moore,Daniel Gordon,Arie Zigler,Dmitri Kaganovich,Thomas M. Antonsen +9 more
TL;DR: In this article, a three-dimensional envelope equation for the laser field is derived that includes nonparaxial effects such as group velocity dispersion, as well as wakefield and relativistic nonlinearities.
Journal ArticleDOI
Theory and Simulation of the Gyrotron Traveling Wave Amplifier Operating at Cyclotron Harmonics
TL;DR: In this paper, an analytical expresion for the efficiency of the gyrotron traveling wave amplifier is derived for the case of non-fundamental cyclotron harmonic interaction, which scales the efficiency with respect to the modes and parameters of operation.
Journal ArticleDOI
Nonlinear wake‐field generation and relativistic focusing of intense laser pulses in plasmas
TL;DR: In this paper, the authors studied the generation of nonlinear wake fields by an intense, short laser pulse and the relativistic optical guiding of intense laser pulses in plasmas with a nonlinear, self-consistent model of laser-plasma interactions.
