Currents and Associated Electron Scattering and Bouncing Near the Diffusion Region at Earth’s Magnetopause

Abstract: Based on high-resolution measurements from NASA’s Magnetospheric Multlscale mission, we present the dynamics of electrons associated with current systems observed near the diffusion region of magnetic reconnection at Earth’s magnetopause. Using pitch angle distributions (PAD) and magnetic curvature analysis, we demonstrate the occurrence of electron scattering in the curved magnetic field of the diffusion region down to energies of 20eV. We show that scattering occurs closer to the current sh…
