Interplay between long and short wavelength instabilities feeding the microturbulence within the foot of a quasi-perpendicular supercritical shock: 2D PIC numerical simulations

Abstract

In supercritical shocks a substantial fraction of ions is reflected at the steep shock ramp. The beam of reflected ions carries a considerable amount of energy and is a main source of microturbulence in the shock’s foot. For quasi- perpendicular geometries the speed of the reflected ions is mostly directed at 90◦ to the background magnetic field Bo. This enables streaming instabilities excited by the relative drifts between incoming ions, reflected ions, and electrons across Bo.
