Abstract
Numerical simulations are presented of the acceleration of charged particles in a
single or multiple Harris-type Reconnecting Current Sheet (RCS). We start with
thermal (Maxwellian) initial particle distributions at 2 106
K. The main goal
is to understand how acceleration in a reconnection site affects the final form of the
energy and pitch angle distributions, as well as the X-Ray spectra produced on the
assumption of a thick target model. These quantities are explored in a parametric
space including a) the particle species, b) the relative strengths of the magnetic
and electric field components, and c) the number of successive scattering events
in a reconnection site including multiple RCSs with random orientation and field
