Nondiffusive transport regimes for suprathermal ions in turbulent plasmas.
The understanding of the transport of suprathermal ions in the presence of turbulence is important for fusion plasmas in the burning regime that will characterize reactors, and for space plasmas to understand the physics of particle acceleration. Here, three-dimensional measurements of a suprathermal ion beam in the toroidal plasma device TORPEX are presented. These measurements demonstrate, in...

متن کاملKinetic Theory of Anomalous Transport of Suprathermal Particles
Investigation of behavior of fast electrons in toroidal discharges was performed. The kinetic equation, describing evolution of fast particle distribution was derived and analyzed. Semi analytical solution of the kinetic equation was obtained into suprathermal energy region. External electric field, anomalous transport, nonuniformity of mean magnetic field and collisions was shown to be an impo...
متن کاملSuprathermal electron evolution in a Parker spiral magnetic field
[1] Suprathermal electrons (>70 eV) form a small fraction of the total solar wind electron density but serve as valuable tracers of heliospheric magnetic field topology. Their usefulness as tracers of magnetic loops with both feet rooted on the Sun, however, most likely fades as the loops expand beyond some distance owing to scattering. As a first step toward quantifying that distance, we const...
متن کاملNondiffusive suprathermal ion transport in simple magnetized toroidal plasmas.
We investigate suprathermal ion dynamics in simple magnetized toroidal plasmas in the presence of electrostatic turbulence driven by the ideal interchange instability. Turbulent fields from fluid simulations are used in the nonrelativistic equation of ion motion to compute suprathermal tracer ion trajectories. Suprathermal ion dispersion starts with a brief ballistic phase, during which particl...
