A Deterministic Ionization Algorithm for the OSIRIS Particle-in-Cell Framework
Stephen DiIorio, Ricardo Fonseca, Frank Tsung +2
Ionization is critical in the formation and evolution of plasma dynamics; collisional ionization, in particular, is an often overlooked source of electrons when dealing with laser-…
Ion acceleration in electrostatic collisionless shock: on the optimal density profile for quasi-monoenergetic beams
E. Boella, F. Fiúza, A. Stockem Novo +2
A numerical study on ion acceleration in electrostatic shock waves is presented, with the aim of determining the best plasma configuration to achieve quasi-monoenergetic ion beams…
Mitigation of the hose instability in plasma-wakefield accelerators
T. J. Mehrling, R. A. Fonseca, A. Martinez de la Ossa +1
Current models predict the hose instability to crucially limit the applicability of plasma-wakefield accelerators. By developing an analytical model which incorporates the evolutio…
Ion motion in the wake driven by long particle bunches in plasmas
J. Vieira, R. A. Fonseca, W. B. Mori +1
We explore the role of the background plasma ion motion in self-modulated plasma wakefield accelerators. We employ J. Dawson's plasma sheet model to derive expressions for the tran…
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.…
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…
