Drift Motion and Instability of a Plasma Injected into a Curved Magnetic Field

Abstract

With the aim of realization of an injected type of Tokamak device, the drift motion and instabilities of a plasma in a curved magnetic field are studied experimentally. For this purpose a curved magnetic field with a straight section is constructed. The plasma is produced by a coaxial gun which is installed at the end of the straight section. It is found that the transmission of the plasma is closely related to the compensation of polarization field through the straight section and to the occurence of an instability.
