A robust disruption mitigation system (DMS) requires accurate characterization of key disruption timescales, one of the most notable being the thermal quench (TQ). Recent modeling of shattered pellet injection (SPI) into ITER plasmas, using JOREK and INDEX, suggests long TQ durations (6–10 ms) and slow cold front propagation due to the large p…

In this work we present the assessment framework for magnetic equilibrium controllers on MAST-U spherical tokamak. Such controllers are essential for MAST-U since exhaust physics and core-edge integration studies require advanced divertor plasma configurations. The developed framework is based on the TokSys suite of plasma control codes, which was …

A real-time plasma magnetic equilibrium controller has been developed to aid in the precise control of advanced configurations such as double-null, super-X, X-point target and X-divertor for the first time on the MAST Upgrade (MAST-U) tokamak. Successful real-time magnetic equilibrium control of different plasma shape control variables during th…
