Abstract

The linear stability of the electrostatic drift waves in slab geometry has been studied analytically and numerically. The effects of a magnetic field with shear, of the finite Larmor radius, of electron streaming, of a temperature gradient and of collisions have been considered. The analytical solution has been obtained using the matched asymptotic expansion technique, and an expression for the critical streaming parameter has been derived. Finally, assuming that the transport in the Reversed Field Pinches is dominated by this instability, a scaling law for the temperature in such machines is derived.
