The power exhaust constrained SPARC separatrix operational space
B. Lomanowski, T. Eich, J. D. Lore +3
In this work we extrapolate the separatrix operational space (SepOS) projections to SPARC and introduce detachment access criteria, thus formulating the combined power exhaust cons…
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+…
A simple, accurate model for detachment access
Thomas Body, Arne Kallenbach, Thomas Eich
In next-step fusion tokamaks such as SPARC and ITER, achieving high levels of scrape-off-layer power dissipation will be essential to protect the divertor while maintaining good co…
Detachment scalings derived from 1D scrape-off-layer simulations
Thomas Body, Thomas Eich, Adam Q Kuang +4
Fusion power plants will require detachment to mitigate sputtering and keep divertor heat fluxes at tolerable levels. Controlling detachment on these devices may require the use of…
The separatrix operational space of next-step fusion experiments: From ASDEX Upgrade data to SPARC scenarios
Thomas Eich, Thomas Body, Michael Faitsch +13
Fusion power plants require ELM-free, detached operation to prevent divertor damage and erosion. The separatrix operational space (SepOS) is proposed as a tool for identifying acce…
