Abstract
Electron and proton acceleration by a super‐Driecer electric field is investigated in a reconnecting current sheet (RCS) with guiding field. The particle trajectories and energy spectra are calculated numerically for different magnetic field topologies by solving motion equation in the test particle and PIC approaches. Three mechanisms of particle acceleration inside an RCS are considered: a drifted electric field caused by the plasma inflows formed during a magnetic reconnection process, polarization electric field induced by the accelerated protons and electrons extracted from PIC simulations and turbulent electric field induced by accelerated particles. Electron and proton densities, energy spectra inside an RCS and at ejection are found to be strongly affected by a magnetic field topology and induced electric fields leading to a strong increases of the energy of accelerated particles in addition to the energy gained by the drifted electric field.
