Numerical instability due to relativistic plasma drift in EM-PIC simulations
Xinlu Xu, Peicheng Yu, Samual F. Martins +6
The numerical instability observed in the Electromagnetic-Particle-in-cell (EM-PIC) simulations with a plasma drifting with relativistic velocities is studied using both theory and…
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…
Convective Raman Amplification of Light Pulses Causing Kinetic Inflation in Inertial Fusion Plasmas
Ian N. Ellis, David J. Strozzi, Benjamin J. Winjum +5
We perform 1D particle-in-cell (PIC) simulations using OSIRIS, which model a short-duration (~500/ω0 FWHM) scattered light seed pulse in the presence of a constant counter-propagat…
