Abstract
We present selective results regarding the dynamics of charged particles (electrons
and protons) in a non-neutral 3D reconnecting current sheet model. The prop-
erties of the orbits are reproduced by analytical methods based on a hamiltonian
formalism. There are both trapped and escaping orbits. Trapped orbits are ana-
lyzed in terms of PoincarŽe surfaces of sections. In addition, the kinetic energy gain
of the escaping particles, is calculated relative to the initial particle energy and to
the physical parameters of the current sheet.
1 Introduction
Charged particle acceleration is one of the most puzzling prob-
lems in Astrophysics. One case of particular interest is the ac-
celeration process during the eruption of solar flares (for re-
