Advancements in NCSX Modeling: Equilibrium, Transport, Heating, and Stability Contributions

This document outlines the significant contributions to the NCSX modeling efforts at ORNL and Auburn, focusing on various facets of plasma behavior. Key advancements include the V3FIT rapid 3D reconstruction for improved equilibrium modeling, momentum transport dynamics, and electric field evolution using the AORSA code. The interactions with gyrokinetic codes for stellarator confinement scaling and the development of stability models like STELLGAP highlight the collaborative nature of these research efforts. Connections to particle transport models and extended MHD work further enhance our understanding of plasma stability and transport.

  1. ORNL theory/modeling contributions to NCSX • Equilibrium • V3FIT: rapid 3D reconstruction (ORNL/Auburn/GA) • VMEC with islands (under development) - goal: fast enough to include inside optimization loop • Transport • Momentum transport, plasma flows, bootstrap current • Electric field evolution/diffusion, f viscous stress tensor, flow evolution • Predict Er/flow shearing rates w/wo external momentum sources (NBI) • Connection to gyrokinetic codes, stellarator confinement scaling studies • Heating • AORSA code includes 3D option: has been applied to LHD • Connect 3D codes to SWIM interface (currently includes TRANSP) • Stability • STELLGAP: Alfvén gaps and mode structure • Connect to particle code (DELTA5D) for energetic particle transport/reduced stability models • Joint work with Y. Todo (NIFS) on extended MHD/closure relations
