Description
A coupled system of linear integral equations are derived from the electromagnetic gyrokinetic equations and solved in straight and sheared slab geometries. Simulation results of a finite-β modified ion-temperature-gradient-driven instability in a sheared geometry are presented. It is shown for typical tokamak parameters that the fundamental l=0 slab mode can be completely stabilized at β∼1% while the l=1 slab mode persists
