Direct Laser Acceleration of Bethe-Heitler positrons in laser-channel interactions
Bertrand Martinez, Robert Babjak, Marija Vranic
Positron creation and acceleration is one of the major challenges for constructing future lepton colliders. On the one hand, conventional technology can provide a solution, but at…
Radiation-dominated injection of positrons generated by the nonlinear Breit-Wheeler process into a plasma channel
Dominika Maslarova, Bertrand Martinez, Marija Vranic
Plasma acceleration is considered a prospective technology for building a compact multi-TeV electron-positron collider in the future. The challenge of this endeavor is greater for…
Numerical investigation of spallation neutrons generated from petawatt-scale laser-driven proton beams
B. Martinez, S. N. Chen, S. Bolaños +15
Due to their high cost of acquisition and operation, there are still a limited number of high-yield, high-flux neutron source facilities worldwide. In this context, laser-driven ne…
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…
