Energy-Preserving Coupling of Explicit Particle-In-Cell with Monte Carlo Collisions
Jean-Luc Vay, Justin Ray Angus, Olga Shapoval +3
The Particle-In-Cell (PIC) and Monte Carlo Collisions (MCC) methods are workhorses of many numerical simulations of physical systems. Recently, it was pointed out that, while the t…
PIC-JRm: a pseudo-spectral Particle-In-Cell formulation with arbitrary charge and current densities time dependencies for the modeling of relativistic plasmas
Olga Shapoval, Edoardo Zoni, Remi Lehe +2
This paper introduces a novel formulation of the Particle-In-Cell (PIC) method for the modeling of relativistic plasmas, which leverages the ability of the Pseudo-Spectral Analytic…
Absorption of charged particles in Perfectly-Matched-Layers by optimal damping of the deposited current
Remi Lehe, Aurore Blelly, Lorenzo Giacomel +2
Perfectly-Matched Layers (PML) are widely used in Particle-In-Cell simulations, in order to absorb electromagnetic waves that propagate out of the simulation domain. However, when…
Investigation of the dynamics of ionization induced injected electrons under the influence of beam loading effects
P. Lee, T. L. Audet, R. Lehe +3
In laser-driven wakefield, ionization induced injection is an efficient way to inject electrons in the plasma wave. A detailed study on the beam dynamics under the influence of bea…
Saturation of the hosing instability in quasi-linear plasma accelerators
Remi Lehe, Carl B. Schroeder, Jean-Luc Vay +2
The beam hosing instability is analyzed theoretically for a witness beam in the quasi-linear regime of plasma accelerators. In this regime, the hosing instability saturates, even f…
Optimization of laser-plasma injector via beam loading effects using ionization-induced injection
P. Lee, G. Maynard, T. L. Audet +3
Simulations of ionization induced injection in a laser driven plasma wakefield show that high-quality electron injectors in the 50-200 MeV range can be achieved in a gas cell with…
Elimination of Numerical Cherenkov Instability in flowing-plasma Particle-In-Cell simulations by using Galilean coordinates
Remi Lehe, Manuel Kirchen, Brendan B. Godfrey +2
Particle-In-Cell (PIC) simulations of relativistic flowing plasmas are of key interest to several fields of physics (including e.g. laser-wakefield acceleration, when viewed in a L…
Stable discrete representation of relativistically drifting plasmas
Manuel Kirchen, Remi Lehe, Brendan B. Godfrey +5
Representing the electrodynamics of relativistically drifting particle ensembles in discrete, co-propagating Galilean coordinates enables the derivation of a Particle-in-Cell algor…
Laser-plasma interactions with a Fourier-Bessel Particle-in-Cell method
Igor A. Andriyash, Remi Lehe, Agustin Lifschitz
A new spectral particle-in-cell (PIC) method for plasma modeling is presented and discussed. In the proposed scheme, the Fourier-Bessel transform is used to translate the Maxwell e…
A spectral, quasi-cylindrical and dispersion-free Particle-In-Cell algorithm
Remi Lehe, Manuel Kirchen, Igor A. Andriyash +2
We propose a spectral Particle-In-Cell (PIC) algorithm that is based on the combination of a Hankel transform and a Fourier transform. For physical problems that have close-to-cyli…
Observation of longitudinal and transverse self-injections in laser-plasma accelerators
S. Corde, C. Thaury, A. Lifschitz +7
Laser-plasma accelerators can produce high quality electron beams, up to giga-electronvolts in energy, from a centimeter scale device. The properties of the electron beams and the…
