Query: Turbulence-driven ion beams in the magnetospheric Kelvin-Helmholtz
  instability   The description of the local turbulent energy transfer, and the
high-resolution ion distributions measured by the Magnetospheric Multiscale
mission, together provide a formidable tool to explore the cross-scale
connection between the fluid-scale energy cascade and plasma processes at
sub-ion scales. When the small-scale energy transfer is dominated by
Alfv\'enic, correlated velocity and magnetic field fluctuations, beams of
accelerated particles are more likely observed. Here, for the first time we
report observations suggesting the nonlinear wave-particle interaction as one
possible mechanism for the energy dissipation in space plasmas.
