Transport of high-energy charged particles through spatially-intermittent turbulent magnetic fields
Identifying the sources of the highest energy cosmic rays requires understanding how they are deflected by the stochastic, spatially intermittent intergalactic magnetic field.

| description | Identifying the sources of the highest energy cosmic rays requires understanding how they are deflected by the stochastic, spatially intermittent intergalactic magnetic field. Here we report measurements of energetic charged-particle propagation through a laser-produced magnetized plasma with
these properties. We characterize the diffusive transport of the particles experimentally. The results
show that the transport is diffusive and that, for the regime of interest for the highest-energy cosmic
rays, the diffusion coefficient is unaffected by the spatial intermittency of the magnetic field.
