Amplitude Transport along Electromagnetic Rays in Tokamak Plasmas
نویسندگان
چکیده
Assimilating radio-frequency waves with rays, this thesis examines the transport of electromagnetic power in a cold plasma, for heating and current-drive applications in tokamaks. Conservation laws are used to compute both the wave amplitude and phase in the Eikonal approximation and extend the RAYcON code to account for phenomena such as focusing until linear conversion is encountered. Simulations were performed in Matlab and show how the amplitude varies as the ray propagates into the plasma.

Nonlinear electromagnetic gyrokinetic simulations of tokamak plasmas
One of the central physics issues currently targeted by nonlinear gyrokinetic simulations is the role of finite-β effects. The latter change the MHD equilibrium, introduce new dynamical space and time scales, alter and enlarge the zoo of electrostatic microinstabilities and saturation mechanisms, and lead to turbulent transport along fluctuating magnetic field lines. It is shown that the electr...
متن کاملFull f gyrokinetic simulation of transpor t in tokamak plasmas
Introduction: The electromagnetic gyrokinetic (GK) plasma simulation [1] for toroidal magnetic fusion devices has become a standard tool for turbulence analysis. Recently, it has been recognized that transport involving dynamic changes in profiles requires modelling with full f GK methods [2]. In the present work, we report on transport simulations for the FT-2 tokamak plasma with a full f nonl...
متن کاملTurbulent electron thermal transport in tokamaks
The origin of anomalous electron thermal turbulence from spatial gradients in magnetized plasmas is described. Laboratory experiments demonstrating key features of drift waves are reviewed. The turbulent electromagnetic fields produce an anomalous transport that scales with both the gradient parameters and microscopic plasma scale length parameters. The change from the micro-scale dominated gyr...
متن کاملSelf-regulated oscillation of transport and topology of magnetic islands in toroidal plasmas
The coupling between the transport and magnetic topology is an important issue because the structure of magnetic islands, embedded in a toroidal equilibrium field, depends on the nature of the transport at the edge of the islands. Measurements of modulated heat pulse propagation in the DIII-D tokamak have revealed the existence of self-regulated oscillations in the radial energy transport into ...
