Ballooning instability precursors to high β disruptions

Description

Strongly ballooning modes have been found as precursors to high β disruptions on TFTR. The modes are typically localized to a region spanning about 60 degree in the toroidal direction. The toroidal localization is associated with lower frequency, global Magneto-Hydro-Dynamic (MHD) activity, typically an ideal n = 1 kink mode. They have moderate to high frequency (f = 10--20 frot), implying toroidal mode numbers in the range n = 10--20. The growth rates for the modes are large, of order 104/sec
