Query: Turbulent transport of fast ions in tokamak plasmas in the presence of
  resonant magnetic perturbations   The effects of resonant magnetic perturbations on the turbulent transport of
fast ions in tokamak devices are investigated using a theoretical transport
model of test-particle type. The direct numerical simulation method is used to
compute, via the transport model, the diffusion coefficients. The numerical
results are in good agreement with other, analytically derived, estimations. It
is found that finite Larmor radius effects decrease algebraically the
transport, while the amplitude of magnetic perturbations has an opposite
effect. In the presence of stochastic dynamics, the asymmetric toroidal
magnetic field induces a small, radial, outward pinch. A synergistic mechanism
of non-linear coupling between turbulence and magnetic perturbations enhances
the radial diffusion. General scaling laws are proposed for the transport
coefficients.
