Steady state, core, operational optimization of an ARC-like tokamak via plasma composition and shape
A. Saltzman, P. Rodriguez-Fernandez, A. Ho +8
Impurity composition, plasma shape, and pedestal density all provide strong levers on fusion power. Here, we explore the ways in which their variation changes fusion power and seek…
Impact of model uncertainty on SPARC operating scenario predictions with empirical modeling
A. Saltzman, P. Rodriguez-Fernandez, T. Body +2
Understanding and accounting for uncertainty helps to ensure next-step tokamaks such as SPARC will robustly achieve their goals. While traditional Plasma OPerating CONtour (POPCON)…
MANTA: A Negative-Triangularity NASEM-Compliant Fusion Pilot Plant
MANTA Collaboration, G. Rutherford, H. S. Wilson +38
The MANTA (Modular Adjustable Negative Triangularity ARC-class) design study investigated how negative-triangularity (NT) may be leveraged in a compact, fusion pilot plant (FPP) to…
Core performance predictions in projected SPARC first-campaign plasmas with nonlinear CGYRO
P. Rodriguez-Fernandez, N. T. Howard, A. Saltzman +7
This work characterizes the core transport physics of SPARC early-campaign plasmas using the PORTALS-CGYRO framework. Empirical modeling of SPARC plasmas with L-mode confinement in…
Enhancing predictive capabilities in fusion burning plasmas through surrogate-based optimization in core transport solvers
P. Rodriguez-Fernandez, N. T. Howard, A. Saltzman +6
This work presents the PORTALS framework, which leverages surrogate modeling and optimization techniques to enable the prediction of core plasma profiles and performance with nonli…
