Compton driven beam formation and magnetisation via plasma microinstabilities
Bertrand Martinez, Thomas Grismayer, Luís O. Silva
Compton scattering of gamma rays propagating in a pair plasma can drive the formation of a relativistic electron positron beam. This process is scrutinised theoretically and numeri…
Synchrotron radiation from ultrahigh-intensity laser-plasma interactions and competition with Bremsstrahlung in thin foil targets
Bertrand Martinez, Emmanuel d'Humières, Laurent Gremillet
By means of particle-in-cell numerical simulations, we investigate the emission of high-energy photons in laser-plasma interactions under ultrahigh-intensity conditions relevant to…
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…
Synchrotron emission from nanowire-array targets irradiated by ultraintense laser pulses
B. Martinez, E. D'Humières, L. Gremillet
We present a numerical study, based on two-dimensional particle-in-cell simulations, of the synchrotron emission induced during the interaction of femtosecond laser pulses of inten…
