Current-driven drift modes in sheared magnetic field
Abstract
The radial eigenmode problem for current-driven drift modes in a plasma slab with sheared magnetic field is solved including the full electron dynamics and effects of electron temperature gradient and electron-ion collisions. Particular attention is given to the eigenmode structure and comparisons with the universal drift mode are made. The threshold current for the onset of current-driven drift mode is found to be close to that predicted by analytic theory and not greatly affected by electron temperature gradient or collisionality.
