Abstract

The electrostatic flute-type instability in an inhomogeneous magnetic field is one of the most important modes in fusion research. A model of this mode in terms of an equivalent gravitation force has earlier been treated by conventional normal mode analysis, also including finite Larmor radius (FLR) effects. Such an analysis does not apply to the case of large particle excursions, such as those due to large Larmor radius (LLR) effects. At this stage there does not exist any analytic kinetic approach by which the LLR effects can be fully treated in a quasi-neutral plasma. The aim of this paper is not to present a final solution of the LLR effects on the present instability, but merely to formulate the basic equations for a proposed computer analysis.
