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…
Core-edge integrated modeling of ARC: on the effect of impurity transport and detachment conditions
Marco Muraca, Pablo Rodriguez-Fernandez, Nathaniel T. Howard +5
Integrated modeling of ARC H-modes has been conducted to assess the feasibility of high-performance scenarios compatible with divertor detachment. The analysis incorporates self-co…
Impurity peaking of SPARC H-modes: a sensitivity study on physics and engineering assumptions
Marco Muraca, Pablo Rodriguez-Fernandez, Joe Hall +5
In this paper, an overview of the impurity transport for three H-mode plasmas in the upcoming SPARC tokamak has been provided. The simulations have been performed within the ASTRA+…
Integrated Modeling of SPARC H-mode Scenarios: Exploration of the Impact of Modeling Assumptions on Predicted Performance
Marco Muraca, Pablo Rodriguez-Fernandez, Nathaniel T. Howard +3
In this paper an extensive database of SPARC H-modes confinement predictions has been provided, to assess its variability with respect to few input assumptions. The simulations hav…
