The ITER disruption mitigation trigger: developing its preliminary design

Abstract: A concept for the generation of the trigger for the ITER disruption mitigation system is described in this paper. The issuing of the trigger will be the result of a complex decision process, taken by the plasma control system, or by the central interlock system, determining that the plasma is unavoidably going to disrupt-or has disrupted-and that a fast mitigated shutdown is required. Given the redundancy of the mitigation system, the plasma control system must also formulate an injection scheme and specify wh… Show more

“…Within this process more operational limits will be approached, which will require appropriate control tools to ensure safe machine operation. This includes control schemes for reliable disruption avoidance and mitigation [60], full RT wall load monitoring [61,62], divertor radiated power control [63,64] or burn control [65].…”

“…During the divertor phases, the key is, of course, to correct the vertical position of the current centroid. In the worst cases, the disruption mitigation system [23] may be invoked to ensure that FW panel overloading is completely avoided.…”

“…Due to the complexity of physics related to disruption, the solution based on physical understanding is quite difficult. Instead, using a machine learning-based disruption predictor to forecast disruptions, and then using 'soft landing' techniques like MGI to mitigate the harmful effects is the focus of research now [4].…”
