Active Disruption Avoidance and Trajectory Design for Tokamak Ramp-downs with Neural Differential Equations and Reinforcement Learning
Allen M. Wang, Oswin So, Charles Dawson +3
The tokamak offers a promising path to fusion energy, but plasma disruptions pose a major economic risk, motivating considerable advances in disruption avoidance. This work develop…
Implications of Vertical Stability Control on the SPARC Tokamak
A. O. Nelson, D. T. Garnier, D. J. Battaglia +5
To achieve its performance goals, SPARC plans to operate in equilibrium configurations with a strong elongation of , destabilizing the vertical inst…
Hybridizing Physics and Neural ODEs for Predicting Plasma Inductance Dynamics in Tokamak Fusion Reactors
Allen M. Wang, Darren T. Garnier, Cristina Rea
While fusion reactors known as tokamaks hold promise as a firm energy source, advances in plasma control, and handling of events where control of plasmas is lost, are needed for th…
Design of Passive and Structural Conductors for Tokamaks Using Thin-Wall Eddy Current Modeling
A. F. Battey, C. Hansen, D. Garnier +5
A new three-dimensional electromagnetic modeling tool ThinCurr has been developed using the existing PSI-Tet finite-element code in support of conducting structure design work for…
Runaway electron deconfinement in SPARC and DIII-D by a passive 3D coil
V. A. Izzo, I. Pusztai, K. Särkimäki +7
The operation of a 3D coil--passively driven by the current quench loop voltage--for the deconfinement of runaway electrons is modeled for disruption scenarios in the SPARC and DII…
