Electron Landau damping of radio-frequency waves in a toroidal plasma with Solov’ev equilibrium
Longitudinal permittivity elements are derived for RF waves in a toroidal plasma with Solov’ev type equilibrium by solving the drift-kinetic equation for untrapped and trapped particles. Our dielectric characteristics are suitable to estimate the wave dissipation by electron Landau damping in the...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Longitudinal permittivity elements are derived for RF waves in a toroidal plasma with Solov’ev type equilibrium by
solving the drift-kinetic equation for untrapped and trapped particles. Our dielectric characteristics are suitable to
estimate the wave dissipation by electron Landau damping in the frequency range of the Alfvén and fast magnetosonic
waves, for both the large and low aspect ratio tokamaks with circular, elliptic and D-shaped magnetic surfaces.
Contributions of the untrapped and usual trapped electrons to the imaginary part of the longitudinal permittivity are
computed for a spherical tokamak plasma in the wide range of wave frequencies at the different magnetic surfaces. |
