Simultaneous Measurements of the Plasma Current Profile and Instabilities in a Tokamak
Abstract
In a small-scale tokamak, magnetohydrodynamic instabilities of small wave numbers, including the m=1 mode with positive voltage spikes, were observed. They were identified as kink modes and resistive tearing modes, by a direct measurement of the plasma current profile. Relations between the fluctuations and the current profile show a qualitative agreement with the theory of kink and resistive tearing modes.
