MHD precursor to disruption in Iran tokamak 1

The purpose of this paper is to further investigate the major disruptions occurring in low-q(a) discharges in Iran Tokamak 1, and to compare the theoretical and experimental results for the rate of island growth. The study of precursor phase of disruption can be predicted and avoided using suitable control systems. In this paper are described the stability analysis and the observed growth rates indicate that the rotating modes are tearing modes.Comment: 12th International Congress on Plasma Physics, 25-29 October 2004, Nice (France
