摘要：

The aim of this study is to find out the most suitable parameters for improving the accuracy of a Particle-in-cell (PIC) simulations for laser wakefield acceleration in gaseous target. We refer mainly to the grid parameters, the number of cells on horizontal and vertical grid, but also to the number of particles per cell. Our results show that for the same simulation but for different number of cells on the grids, the values of the electron output energy differes and approaches different convergence zones. Besides, we investigated the change of the simulation duration as a function of the number of MPI processes, in order to find the most efficent number in the case of our machine.
