Kink Modes and Surface Currents Associated With Vertical Displacement Events
Authors: Janardhan Manickam, Allen Boozer and Stefan Gerhardt
Abstract: The fast termination phase of a Vertical Displacement Event, VDE, in a tokamak, is modeled as a
sequence of shrinking equilibria, where the core current profile remains constant so that the safety-factor
at the axis, qaxis tedi, remains fixed and the qedge systematically decreases. At some point the n = 1.
