抄録

A set of coupled eigenmode equations for drift and shear Alfvén mode in a sheared magnetic field is solved numerically, including effects of the parallel current, the full ion dynamics and electron-ion collisions. Detailed studies are made on the eigenmode structures of both the modes and combined effects of current and finite-β. An outstanding result is that the Current-driven drift mode shows, at some moderate β value, a peculiarity in dispersion and its eigenmode structure is deformed to a shape different from the drift mode one, which means the strong coupling of drift mode to shear Alfvén mode due to the combined effects. In the most cases except this, the effects of finite-β and collisions are found to be stabilizing.
