${\tt ALaDyn}$ : A High-Accuracy PIC Code for the Maxwell–Vlasov Equations

In this paper, we present acceleration by laser and dynamics of charged particles (ALaDyn), a particle-in-cell code, to investigate the interaction of a laser pulse with a preformed plasma and/or an externally injected beam. The code, fully parallelized, works in 1D, 2D, and 3D Cartesian geometry, and it is based on compact high-order finite-difference schemes ensuring higher spectral accuracy. We discuss the features, the performances, and the validation tests of the code. We finally present a preliminary application on a physically relevant case based on the PLASMON-X experiment of the CNR-INFN.
