Title:

Effect of Electric Field Inhomogeneities on Drift Wave Instabilities and Anomalous Transport

Date of publication:

Jan. 1991

Key words:

Sheared EXB Rotation, Radial Electric Field, Drift Instability, Tokamaks, Ion Landau Damping, H-mode

Abstract:

Effect of inhomogeneity of radial electric field on drift wave instabilities is investigated. Curvature of static potential gives rise to an additional Landau resonance. Critical conditions for the stability due to sheared ExB motion of ions are estimated for various modes. Effect on anomalous transport coefficient is also discussed.
