Turbulent Transport-Limited Pedestals in Tokamaks
J. F. Parisi, D. R. Hatch, P. Y. Li +5
H-mode operation of tokamak fusion plasmas free of dangerous Type 1 edge-localized-modes (ELMs) requires a non-ELM mechanism for saturating the edge pedestal growth. One possible m…
Prediction of ELM-free Operation in Spherical Tokamaks With High Plasma Squareness
J. F. Parisi, J. W. Berkery, K. Imada +5
We predict that high plasma squareness in spherical tokamaks (STs) could result in edge-localized-mode (ELM)-free H-mode. The effect of squareness on gyrokinetic and peeling-balloo…
HIPED: Machine Learning Framework for Spherical Tokamak Pedestal Prediction and Optimization
J. F. Parisi, J. G. Clark, J. W. Berkery +4
We introduce a Machine Learning framework, HIPED (HeIght and width Predictor for Edge Dynamics), for predicting and optimizing pedestal and core performance in spherical tokamak pl…
Doubling Fusion Power with Volumetric Optimization in Magnetic Confinement Fusion Devices
J. F. Parisi, J. W. Berkery, A. Sladkomedova +17
A technique, volumetric power optimization, is presented for enhancing the power output of magnetic confinement fusion devices. Applied to a tokamak, this approach involves shiftin…
