Larmor radius effects on impurity transport in turbulent plasmas
  Test particle transport determined by the Lorentz force in turbulent magnetized plasmas is studied. The time dependent diffusion coefficient, valid for the whole range of parameters, is obtained by developing the decorrelation trajectory method. The effects of Larmor gyration in the presence of trapping are analyzed and several transport regimes are evidenced.
