The anomalous transport of energetic ions in the presence of turbulent fields is investigated. Nonlinear simulations of a steady-state ITER [R. Aymar et al., Nucl. Fusion 41, 1301 (2001)] scenario have been carried out using the gyrokinetic turbulence code GENE [F. Jenko et al., Phys. Plasmas 7, 1904 (2000)], modeling the suprathermal particles as high temperature Maxwellian distributions in the passive tracer limit. Velocity space analysis shows that single particle diffusivities of ions above the critical energy are significantly larger than their neoclassical counterpart.

    We have studied the loss of O+ and O+2 ions at Mars with a numerical model. In our quasi-neutral hybrid model ions (H+, He++, O+, O+2) are treated as particles while electrons form a massless charge-neutralising fluid. The employed model version does not include the Martian magnetic field...
