Nondiffusive 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...
متن کاملA performance study of the conceptual implementation of the GEM-tracking detector in Monte Carlo simulation
PANDA experiment (antiProton ANnihilation at DArmstadt) is one of the key projects of the future FAIR facilities to investigate the reactions of antiprotons with protons and nuclear targets. experiment is designed to serve as a completely extraordinary physical potential due to exploiting the availability of cold and high-intensity beams of antiprotons. One of the significant parts of the ...
متن کاملTime-Resolved Measurements of Suprathermal Ion Transport Induced by Intermittent Plasma Blob Filaments.
Suprathermal ion turbulent transport in magnetized plasmas is generally nondiffusive, ranging from subdiffusive to superdiffusive depending on the interplay of the turbulent structures and the suprathermal ion orbits. Here, we present time-resolved measurements of the cross-field suprathermal ion transport in a toroidal magnetized turbulent plasma. Measurements in the superdiffusive regime are ...
متن کاملBasic investigations of electrostatic turbulence and its interaction with plasma and suprathermal ions in a simple magnetized toroidal plasma
Progress in basic understanding of turbulence and its influence on the transport both of the plasma bulk and of suprathermal components is achieved in the TORPEX simple magnetized torus. This configuration combines a microwave plasma production scheme with a quasi-equilibrium generated by a toroidal magnetic field, onto which a small vertical component is superimposed, simulating a simplified f...
متن کاملMulti-ion plasma expansion in the presence of suprathermal electrons
The self similar expansion of a two-ion plasma is investigated via a multi-fluid model. Our aim is to elucidate the effect of secondary ions on the plasma expansion front, in combination with energetic (suprathermal) electrons in the background. Considering an analytically tractable situation (namely, assuming secondary ions to represent a minority population), and adopting a kappa-type distrib...
