Radiation emission plasmas is often a result of collective effects associated with the dynamics of relativistic charged particles. A common numerical approach to model their motion involves the Particle-In-Cell scheme which solves the full set of Maxwell's equations and the relativistic Lorentz force for the charged particles.
The Radiation Diagnostic for OSIRIS (RaDiO) can retrieve the...
It has been recently shown that a high-current ultrarelativistic electron beam can undergo strong self-focusing due to the Near-Field Coherent Transition Radiation (NF-CTR) emitted when interacting with multiple submicrometer-thick conducting foils [A. Sampath et al., Phys. Rev. Lett. 126, 064801 (2021)]. Particle-In-Cell simulations show that this self-focusing phenomenon is accompanied by...
We present first-principle simulations of coherent synchrotron radiation (CSR) using the large-scale LW3D code [Ryne, R. D., et al. "Large scale simulation of synchrotron radiation using a Lienard-Wiechert approach." Proc. IPAC 46 (2012).] which computes the Lienard-Wiechert fields in 3D from the total number of particles in the bunch. We have applied a straightforward adaptation in the LW3D...
With the rapid development of high-power petawatt class lasers worldwide, exploring the physics in the strong field QED regime will become one of the frontiers for laser-plasma interaction research. Particle-in-cell codes including quantum emission processes are powerful tools for predicting and analyzing future experiments, where the physics of relativistic plasma is strongly affected by...
