DESTABILIZATION OF THE POLOIDAL ROTATION IN A MULTIPLE ION SPECIES TOKAMAK PLASMA

doi:10.1088/1004-423X/7/1/003

Abstract

Abstract The destabilization of the poloidal rotation for the species of ions with the poloidally inhomogeneous sources or sinks is studied in multiple ion species tokamak plasmas. Based on the fluid equations, the evolution equation of the poloidal ion rotation speed is derived analytically. The magnitude of the inhomogeneous sources or sinks needed to destabilize the rotation is shown to be proportional to the ion density. It is suggested that the poloidal plasma rotation can be generated by destabilizing the rotation of the minority ions.
