We explore the possibility of fully replacing a plasma physics kinetic simulator with a graph neural network-based simulator. We focus on this class of surrogate models given the similarity between their message-passing update mechanism and the tradi

An efficient approach that considers a high-intensity twisted laser of moderate energy (few J) is proposed to generate collimated proton bunches with multi-10 MeV energies from a double-layer hydrogen target. Three-dimensional particle-in-cell simula

Current Filamentation Instability (CFI) is of central importance for the propagation of relativistic electron beams in plasmas. It could play an important role in the generation of magnetic fields and of radiation in the after‐glow of gamma ray bur

Simulation results of possible upcoming Plasma Wakefield Accelerator (PWFA) experiments at FACET are presented. In a two‐bunch scenario, the second (accelerated) electron bunch can have multi‐GeV energy gain and a small energy spread after less t

We demonstrate an implementation of the Boris Particle Pusher Algorithm using CUDA-enabled processors. A simplified PIC code is used as a reference for the pusher and several tests are shown. The deployment time from a developer point of view is also

In this paper we propose a methodology for the efficient implementation of Machine Learning (ML)-based methods in particle-in-cell (PIC) codes, with a focus on Monte-Carlo or statistical extensions to the PIC algorithm. The presented approach allows
