TITLE: Collisionless relaxation in the shock front
ABSTRACT: The magnetic field profile of a collisionless shock is shaped mainly by ions. Upon crossing the shock ions begin to gyrate and form a non-gyrotropic distribution. The ion pressure tensor oscillates with the distance from the ramp. These oscillations damp due to collisionless gyrophase mixing. The latter is sensitive to the basic shock parameters. Chances to observe this relaxation are higher for shocks with lower upstream ion temperature.
