The impact of kinetic and global effects on ballooning 2nd stable pedestals of conventional and low aspect ratio tokamaks
M. S. Anastopoulos Tzanis, M. Yang, A. Kleiner +3
The EPED model [P.B. Snyder et al 2011 Nucl. Fusion 51 103016] had success describing the pedestals of the Type-I ELM and QH-mode operations in conventional tokamaks, by combining…
Validation of the GFS model for Gyrokinetic Stability of NSTX Pedestal Data
M. Yang, J. F. Parisi, M. S. Anastopoulos Tzanis +1
This study presents a large database validation of the Gyro Fluid System (GFS) model for linear gyrokinetic stability for high-mode (H-mode) edge transport barrier conditions in th…
Introduction to Stability and Turbulent Transport in Magnetic Confinement Fusion Plasmas
J. F. Parisi
This tutorial provides an accessible introduction to the principles of stability and turbulent transport in magnetic confinement fusion plasmas. Key concepts, models, and practical…
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…
