Electron transport in a radiation-dominated plasma Application to solar corona brightenings
Roland Duclous, Vladimir Tikhonchuk, Marina Leboulanger +3
Bremsstrahlung scattering of fast electrons on ions can be enhanced by the microwave radiation present in the solar corona. It can account for the electron diffusive transport alon…
High-Energy Radiation and Pair Production by Coulomb Processes in Particle-In-Cell Simulations
B. Martinez, M. Lobet, R. Duclous +2
We present a Monte Carlo implementation of the Bremsstrahlung, Bethe-Heitler and Coulomb Trident processes into the particle-in-cell (PIC) simulation framework. In order to address…
From quantum to classical modelling of radiation reaction: a focus on stochasticity effects
F. Niel, C. Riconda, F. Amiranoff +2
Radiation-reaction in the interaction of ultra-relativistic electrons with a strong external electromagnetic field is investigated using a kinetic approach in the weakly quantum re…
Modelling Gamma Ray Emission and Pair Production in High-Intensity Laser-Matter Interactions
C. P. Ridgers, J. G. Kirk, R. Duclous +5
In high-intensity (> 10^21W/cm^2) laser-matter interactions gamma-ray photon emission by the electrons can strongly affect the electron's dynamics and copious numbers of electron-p…
Dense electron-positron plasmas and bursts of gamma-rays from laser-generated QED plasmas
C. P. Ridgers, C. S. Brady, R. Duclous +4
In simulations of a 12.5PW laser (focused intensity I = 4x10^23W/cm^2) striking a solid aluminium target 10% of the laser energy is converted to gamma-rays. A dense electron-positr…
Dense Electron-Positron Plasmas and Ultra-Intense Bursts of Gamma-Rays from Laser-Irradiated Solids
C. P. Ridgers, C. S. Brady, R. Duclous +5
In simulations of a 10PW laser striking a solid we demonstrate the possibility of producing a pure electron-positron plasma by the same processes as those thought to operate in hig…
Monte Carlo calculations of pair production in high-intensity laser-plasma interactions
Roland Duclous, John Kirk, Anthony Bell
Gamma-ray and electron-positron pair production will figure prominently in laser-plasma experiments with next generation lasers. Using a Monte Carlo approach we show that stragglin…
Deterministic Partial Differential Equation Model for Dose Calculation in Electron Radiotherapy
Roland Duclous, Bruno Dubroca, Martin Frank
Treatment with high energy ionizing radiation is one of the main methods in modern cancer therapy that is in clinical use. During the last decades, two main approaches to dose calc…
High order resolution of the Maxwell-Fokker-Planck-Landau model intended for ICF applications
Roland Duclous, Bruno Dubroca, Francis Filbet +1
A high order, deterministic direct numerical method is proposed for the nonrelativistic Vlasov-Maxwell system, coupled with Fokker-Planck-Landau type…
