Weibel-mediated filamentary structures observed in the ICF context
C. Ruyer, S. Bolaños, P. E. Masson Laborde +16
In light of novel and past experimental results, we demonstrate how Weibel-mediated filamentary structures can develop in the expanding plasma plume of a laser-irradiated foil. The…
Accounting for speckle scale beam-bending in classical ray tracing schemes for propagating realistic pulses in indirect drive ignition conditions
C. Ruyer, P. Loiseau, G. Riazuelo +3
We propose a semi-analytical modeling of smoothed laser beams deviation induced by plasma flows. Based on a Gaussian description of speckles, the model includes spatial, temporal a…
Disruption of current filaments and isotropization of magnetic field in counter-streaming plasmas
C. Ruyer, F. Fiuza
We study the stability of current filaments produced by the Weibel, or current filamentation, instability in weakly magnetized counter-streaming plasmas. It is shown that a resonan…
Relativistic electron streaming instabilities modulate proton beams accelerated in laser-plasma interactions
S. Göde, C. Rödel, K. Zeil +16
We report experimental evidence that multi-MeV protons accelerated in relativistic laser-plasma interactions are modulated by strong filamentary electromagnetic fields. Modulations…
Weibel instability-mediated collisionless shocks in laser-irradiated dense plasmas:Prevailing role of the electrons in the turbulence generation
C. Ruyer, L. Gremillet, G. Bonnaud
We present a particle-in-cell simulation of the generation of a collisionless turbulent shock in a dense plasma driven by an ultra-high-intensity laser pulse. From the linear analy…
Nonlinear dynamics of the ion Weibel-filamentation instability: an analytical model for the evolution of the plasma and spectral properties
C. Ruyer, L. Gremillet, A. Debayle +1
We present a predictive model of the nonlinear phase of the Weibel instability induced by two symmetric, counter-streaming ion beams in the non-relativistic regime. This self-consi…
Modeling of radiative and quantum electrodynamics effects in PIC simulations of ultra-relativistic laser-plasma interaction
Mathieu Lobet, Emmanuel d'Humières, Mickael Grech +3
Next generation of ultra-intense laser facilities will lead to novel physical conditions ruled by collective and quantum electrodynamics effects, such as synchrotron-like emission…
Electromagnetic fluctuations and normal modes of a drifting relativistic plasma
C. Ruyer, L. Gremillet, D. Bénisti +1
We present an exact calculation of the power spectrum of the electromagnetic fluctuations in a relativistic equilibrium plasma described by Maxwell-Jüttner distribution functions.…
Collisionless shock formation, spontaneous electromagnetic fluctuations and streaming instabilities
A. Bret, A. Stockem, F. Fiuza +4
Collisionless shocks are ubiquitous in astrophysics and in the lab. Recent numerical simulations and experiments have shown how they can arise from the encounter of two collisionle…
