Turbulence augmented applied magnetic field in compressions

The application of a magnetic field to inertial confinement fusion implosions can relax ignition criteria, which may help otherwise marginal implosions ignite. Such applied fields may be augmented by the presence of (non-radial) flows in compressions, either intentionally or not. Here we study, in a simplified simulation setup, the compression and heating of MHD turbulence and the resulting kinematic dynamo dynamics. In particular we show mechanisms which raise the possibility of various benefits for implosions with applied field: enhanced growth of applied magnetic field during the compression; localization of this enhanced field to a hot spot; and the generation there of a stochastic magnetic field with increased thermal conduction suppression relative to the uniform-applied-field case.
