Title: Final Report for DE-SC0004662 at UCSD

We present results of large scale, fully kinetic 3D simulations of decaying plasma turbulence that span a range of scales from tens of ion gyroradii to the electron Debye length. A significant fraction of the dissipated energy is transferred to ions, in contrast to the scenario where the dominant dissipation is due to Landau damping of wave-like fluctuations. Intense current sheets are formed in the simulation with thicknesses over a range of scales approximately between electron and ion inertial scales. The rate of ion heating is well correlated with intermittency level. Geometrical analysis of the current sheets suggest that magnetic reconnection is active in the present simulation.
