| Abstract | A study of the main quantities that depend on the topology of the orbits of trapped particles, viz, width of banana orbits, second adiabatic invariant, and bootstrap current, is carried out for low-aspect-ratio tokamaks. In order to investigate the variation of these quantities with only the geometry of the magnetic equilibrium configuration, an exact equilibrium model with fixed profiles, i.e., the Soloviev equilibrium model, is used. For tokamaks with small aspect ratio (R/a <2), the width of banana orbits is very narrow as compared to the values obtained for conventional to tokamaks. Configurations with horizontal elongation can have a negative gradient of the second adiabatic invariant, giving rise to the possibility of stabilizing flute modes. It is shown that the bootstrap current depends on the geometrical parameters of the plasma column, that is, triangularity and elongation. The bootstrap current increases with the inverse aspect ratio only for elongated croos-sections of the plasma column. |
