H-VLPL: A three-dimensional relativistic PIC/fluid hybrid code

The novel PIC/fluid hybrid plasma simulation code H-VLPL3D is introduced. In addition to the particle-in-cell algorithm, it uses a new numerical fluid scheme for wake field simulations. Specially designed for the accurate simulation of very long wake fields, this scheme is capable of simulating ∼1000 plasma oscillations of the wake. A comprehensive description of the discretization schemes is given, and we demonstrate the code's correctness and its order of accuracy. Also, its superior efficiency in the plasma wake field acceleration (PWFA) regime is shown.
