The physics of ELM-free regimes in EUROfusion tokamaks
M. G. Dunne, M. Faitsch, O. Sauter +25
The development of operational scenarios without large Type-I ELMs is of utmost importance for the stable operation and longevity of future tokamaks. The EUROfusion tokamak exploit…
Applications of a novel model-based real-time observer for electron density profile control experiments in TCV
F. Pastore, O. Sauter, F. Felici +12
Real-time control of tokamak plasmas encompasses sustaining a high-performance stationary state, avoiding disruptions, and managing ramp-up and ramp-down phases. Real-time estimati…
On the timescales of controlled termination of tokamak plasmas
Simon Van Mulders, Olivier Sauter
The RAPTOR code is used to model how the time required for controlled termination of Ohmic plasmas scales from present tokamaks like TCV and JET, to reactor-grade tokamaks like ITE…
Learning Plasma Dynamics and Robust Rampdown Trajectories with Predict-First Experiments at TCV
Allen M. Wang, Alessandro Pau, Cristina Rea +12
The rampdown phase of a tokamak pulse is difficult to simulate and often exacerbates multiple plasma instabilities. To reduce the risk of disrupting operations, we leverage advance…
Plasma State Monitoring and Disruption Characterization using Multimodal VAEs
Yoeri Poels, Alessandro Pau, Christian Donner +6
When a plasma disrupts in a tokamak, significant heat and electromagnetic loads are deposited onto the surrounding device components. These forces scale with plasma current and mag…
Robust Confinement State Classification with Uncertainty Quantification through Ensembled Data-Driven Methods
Yoeri Poels, Cristina Venturini, Alessandro Pau +4
Maximizing fusion performance in tokamaks relies on high energy confinement, often achieved through distinct operating regimes. The automated labeling of these confinement states i…
