Dataset from: Isolation and Phase-Space Energization Analysis of the Instabilities in Collisionless Shocks

We analyze the generation of kinetic instabilities and their effect on the energiza-
tion of ions in non-relativistic, oblique collisionless shocks using a 3D-3V simulation
by dHybridR, a hybrid particle-in-cell code. At sufficiently high Mach number, quasi-
perpendicular and oblique shocks can experience rippling of the shock surface caused by
kinetic instabilities arising from free energy in the ion velocity distribution due to the
combination of the incoming ion beam and the population of ions reflected at the shock
front. To understand the role of the ripple on particle energization, we devise the new
instability isolation method to identify the unstable modes underlying the ripple and
interpret the results in terms of the governing kinetic instability. We generate velocity-
space signatures using the field-particle correlation technique to look at energy transfer in
phase space from the isolated instability driving the shock ripple, providing a viewpoint
on the different dynamics of distinct populations of ions in phase space. We generate
velocity-space signatures of the energy transfer in phase space of the isolated instability
driving the shock ripple using the field-particle correlation technique. Together, the
field-particle correlation technique and our new instability isolation method provide a
unique viewpoint on the different dynamics of distinct populations of ions in phase space
and allow us to completely characterize the energetics of the collisionless shock under
investigation.
