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…
Magnetic control of particle-injection in plasma based accelerators
J. Vieira, S. F. Martins, V. B. Pathak +3
The use of an external transverse magnetic field to trigger and to control electron self-injection in laser- and particle-beam driven wakefield accelerators is examined analyticall…
Ion dynamics and acceleration in relativistic shocks
S. F. Martins, R. A. Fonseca, L. O. Silva +1
Ab-initio numerical study of collisionless shocks in electron-ion unmagnetized plasmas is performed with fully relativistic particle in cell simulations. The main properties of the…
One-to-one direct modeling of experiments and astrophysical scenarios: pushing the envelope on kinetic plasma simulations
R. A. Fonseca, S. F. Martins, L. O. Silva +3
There are many astrophysical and laboratory scenarios where kinetic effects play an important role. These range from astrophysical shocks and plasma shell collisions, to high inten…
Three-dimensional structure of the laser wakefield accelerator in the blowout regime
J. F. Vieira, S. F. Martins, F. Fiuza +9
Three-dimensional Particle-in-Cell (PIC) simulations with the code QuickPIC are used to illustrate the typical accelerating structures associated with the interaction of an intense…
