The high plasma temperatures expected at reactor conditions in magnetic confinement
fusion toroidal devices suggest that near-marginal operation could be a reality in future …

Super-thermal ions and electrons occur in both space and fusion plasmas. Because these
energetic particles (EP) have large velocities, EP orbits necessarily deviate substantially …

Lévy flights are paradigmatic generalised random walk processes, in which the independent
stationary increments—the'jump lengths'—are drawn from an-stable jump length distribution …

In the last few years it has been demonstrated, both by data analysis and by numerical
simulations, that the transport of energetic particles in the presence of magnetic turbulence …

Fast collisionless shocks in cosmic plasmas convert their kinetic energy flow into the hot
downstream thermal plasma with a substantial fraction of energy going into a broad …

Recent in situ and remote observations suggest that the transport regime associated with
shock-accelerated particles may be anomalous ie the mean square displacement (MSD) of …

The transport of energetic electrons immersed in Alfvénic turbulence in Earth's outer
radiation belt is explored. It is shown how electrons subject to the action of an empirically …

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 …

The confinement of energetic particles in nuclear fusion devices is studied in the presence of
an oscillating radial electric field and an axisymmetric magnetic equilibrium. It is shown that …

We investigate the time evolution of the mean location and variance of a charged particle
subject to random collisions that are Poisson distributed. The particle moves on a plane and …
