Scientific paper

Computer simulations and observations in laboratory and space plasmas have revealed that some incident ions are reflected at perpendicular and quasi-perpendicular high Mach number (i.e., supercritical) shocks. Moreover, these studies have established that the gyration and subsequent thermalization of these ions play a dominant role in the shock dissipation process. Here, a hybrid kinetic simulation is used to study the selection of an incoming ion as either reflected-gyrating or transmitted. It is found that the reflected ions come from a limited region in the upstream velocity space distribution. None of the reflected ions come from the core of the distribution. Whether a particle becomes reflected depends on its energy in the upstream frame and its gyrophase as it encounters the shock.
