Notes:
The sheared slab ηi instability is reconsidered in tokamak plasma with negative magnetic shear. A modified sheared slab model is presented to include both the magnetic shear and its variation with the magnetic surface. The results show that the slow variation of magnetic shear can aggravate the sheared slab ηi instability in the region near the minimum-q magnetic surface and that it has a weak stabilizing role in the plasma core near the axis. However, when the effect of the variation of magnetic shear increases, it can give rise to a stronger slab ηi instability. In addition, a linear mode coupling mechanism could be mediated by the variation of magnetic shear with a magnetic surface. © 1998 American Institute of Physics.
