Coordinate-invariant flux-surface Fourier analysis in tokamaks
Matthew Pharr, Evan Bursch, Nikolas Logan +3
The Fourier spectra of resonant quantities in tokamaks depend on the choice of magnetic coordinates, and an area weighting of the Fourier integrand preserves the resonant coefficie…
Compact Experimental Negative TriAngUlarity Reactor (CENTAUR): A design study for a compact, affordable breakeven tokamak
The CENTAUR Collaboration, Samuel W. Freiberger, Evan Bursch +33
This work presents the compact experimental negative triangularity reactor (CENTAUR), a low overnight cost, high-field tokamak, breakeven reactor design, achieving a predicted tota…
Improved n=1 Empirical Error Field Penetration Threshold Scaling with Ohmic and L-Mode Conventional Tokamak Plasma Discharges
E. M. Bursch, J. K. Park, N. C. Logan +12
This paper presents an updated n=1 error field penetration threshold scaling, which increases fit quality compared to previous error field scaling laws, is produced from an expande…
Effect of Controlled Magnetic Island Bifurcation on Electron Diffusion
Jessica Eskew, D. M. Orlov, B. Andrew +7
Magnetic islands strongly influence cross-field electron transport in magnetized plasmas. In particular, bifurcations of the island topology modify the number and location of O-poi…
Exploring the fusion power plant design space: comparative analysis of positive and negative triangularity tokamaks through optimization
T. Slendebroek, A. O. Nelson, O. M. Meneghini +10
The optimal configuration choice between positive triangularity (PT) and negative triangularity (NT) tokamaks for fusion power plants hinges on navigating different operational con…
