Temporal characteristics of MHD modes initiating disruptions.
Original language description
Tokamak disruptions present a risk to large size devices in terms of forces and heat loads deposited on the PFC. The control system of such devices must thus embed a system for disruption prediction that will trigger mitigation actions if disruption avoidance fails. Disruptions can be predicted by monitoring the growth of MHD instabilities that are eventually responsible for the loss of plasma confinement. MHD modes are observed to be locked (ML) or rotating (ROT) at the onset of the disruption. They are excited by various causes, motivating disruption classification. An empirical scaling law has been derived for the locked mode disruptive amplitude, allowing an estimate of the perturbation amplitude required to disrupt the plasma in ITER. The associated warning times, important for disruption prediction in ITER, have not yet been evaluated.
