Basic schematic of the proposed mechanism. Top left: we assume a power-law power spectrum related to a line width–size relation. Top right: the turbulence driven at scale, ℓ, corresponds to an average density and magnetic field “seen” by the turbulence. Bottom right: Within the turbulence there are reconnection regions of width Δ (Equation (18)). Here, protons bounce between the reconnection fronts. Bottom left: the resulting acceleration, via the Fermi mechanism, results in a power-law energy distribution.
