Turbulent Reconnection Acceleration

The ubiquitous turbulence in astrophysical plasmas is important for both magnetic reconnection and acceleration. We study the particle acceleration during fast 3D turbulent with reconnection-driven turbulence. Particles bounce back forth between inflows due to mirror reflection convergence of strong fields. Via successive head-on collisions, kinetic energy converted into accelerated particles. Turbulence not only regulates inflow speed but also introduces various obliquities respect local As gain escape probability particles depend on speed, spectral index spectrum universal. find it range from $\approx 2.5$ $4$, steepest expected at a guide field, i.e. small angle total incoming field field. Without scattering diffusion needed confining particles, can be very efficient large weak
