The impact of kinetic effects on the properties of relativistic electron-positron shocks
A. Stockem, F. Fiuza, R. A. Fonseca +1
We assess the impact of non-thermally shock-accelerated particles on the magnetohydrodynamic (MHD) jump conditions of relativistic shocks. The adiabatic constant is calculated dire…
Magnetically assisted self-injection and radiation generation for plasma based acceleration
J. Vieira, J. L. Martins, V. B. Pathak +3
It is shown through analytical modeling and numerical simulations that external magnetic fields can relax the self-trapping thresholds in plasma based accelerators. In addition, th…
The ion motion in self-modulated plasma wakefield accelerators
J. Vieira, R. A. Fonseca, W. B. Mori +1
The effects of plasma ion motion in self-modulated plasma based accelerators is examined. An analytical model describing ion motion in the narrow beam limit is developed, and confi…
Transverse self-modulation of ultra-relativistic lepton beams in the plasma wakefield accelerator
J. Vieira, Y. Fang, W. B. Mori +2
The transverse self-modulation of ultra-relativistic, long lepton bunches in high-density plasmas is explored through full-scale particle-in-cell simulations. We demonstrate that l…
Laser-driven shock acceleration of monoenergetic ion beams
F. Fiuza, A. Stockem, E. Boella +7
We show that monoenergetic ion beams can be accelerated by moderate Mach number collisionless, electrostatic shocks propagating in a long scale-length exponentially decaying plasma…
DC magnetic field generation in unmagnetized shear flows
T. Grismayer, E. P. Alves, R. Fonseca +1
The generation of DC magnetic fields in unmagnetized plasmas with velocity shear is predicted for non relativistic and relativistic scenarios either due to thermal effects or due t…
Weibel-instability-mediated collisionless shocks in laboratory with ultraintense lasers
F. Fiuza, R. A. Fonseca, J. Tonge +2
The formation of non-relativistic collisionless shocks in laboratory with ultrahigh intensity lasers is studied via \emph{ab initio} multi-dimensional particle-in-cell simulations.…
Influence of realistic parameters on state-of-the-art LWFA experiments
J. Vieira, S. F. Martins, F. Fiúza +7
We examine the influence of non-ideal plasma-density and non-Gaussian transverse laser-intensity profiles in the laser wakefield accelerator analytically and numerically. We find t…
