The code solves Vlasov-Maxwell system, and outputs electric and magnetic fields, current densities, and densities. Used for manuscript titled 'Interaction of cold streaming protons with the reconnection process' by Tenfjord et al., 2020. Details, simulation setup and design described in manuscript.We employ a 2.5D particle-in-cell simulation to study a scenario where the reconnection process captures cold streaming protons. As soon as the tailward streaming protons become involved, they contribute to the overall momentum balance, altering the initially symmetric dynamics. Adding tailward-directed momentum to the reconnection process results in a tailward propagation of the reconnection site. We investigate how the reconnection process reorganizes itself due to the changing momentum conditions on the kinetic scale, and how the reconnection rate is affected. We find that adding tailward momentum, does not result in a significantly different reconnection rate compared to the case without cold streaming protons, when scaled to the total Alfven velocity. This implies that the effect of changing inflow conditions due to the motion of the reconnection site appears to be minimal. The dynamics of the particles are however, significantly different depending on whether they enter on the tailward or Earthward side of the reconnection site. On one side they are reflected and thermalized, while on the opposite side they are picked-up and accelerated. The particle dynamics result in an asymmetry in the electric field between the two outflow regions. Also, since the initial plasma sheet population is swept up on one side and flushed out on the other, a multiscale diffusion region exists only on one side, resulting in asymmetries in the Hall electric field and in the magnetic field configuration. Our results are important for understanding the development and dynamics of magnetospheric substorms and storms.Fortran, 90Python, 3
