Abstract

In the context of disruption prediction, it is important to determine parameters influencing the mode duration. According to the results presented here, those could be device and disruption-class dependent. A multi-machine comparative approach is important to provide a reliable scaling of locked mode amplitude-based warning times for disruption prediction in ITER. Experimental data from AUG and JET show that 100% success rate in those devices would not be met with only locked mode amplitude used for disruption prediction. Developing reliable multi-parameter disruption prediction algorithms may be necessary to achieve the success rate requirements in ITER (eventually > 95%). The amplitude of rotating modes may be a good candidate signal in this context and it is important to examine what determines the fraction of rotating modes triggering disruptions.
