Description
Magnetic reconnection in the magnetotail efficiently converts stored magnetic energy into particle energy, yet how this energization spans from kinetic scales to global transport remains an open question. We investigate plasma transport and acceleration from magnetotail reconnection to the inner magnetosphere using a multiscale modeling approach. We employ the energy-conserving ECSIM particle-in-cell code, initialized with global MHD-derived fields. Over several minutes of simulated physical time, particles originating in the reconnection region reach the inner magnetosphere and are accelerated up to ~100 keV. We evaluate energy transport by examining ion and electron energy fluxes, the Poynting flux, and changes in particle and electromagnetic power densities. We also explore the role of turbulent electron acceleration in both the reconnection region and Earthward fast flows. Finally, motivated by the computational demands of global kinetic modeling, we conclude with ongoing efforts to improve simulation performance through PETSc integration in iPic3D.
