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…
Quantifying resonant drive in resistive perturbed tokamak equilibria
Matthew Pharr, Nikolas Logan, Carlos Paz-Soldan +1
Resonant drive in tokamaks is routinely quantified using a variety of different metrics that target different aspects of a resonant response to an external perturbation. Two of the…
SPARC Tokamak Error Field Expectations and Physics-Based Correction Coil Design
N. C. Logan, C. E. Myers, R. Sweeney +6
Non-axisymmetric magnetic field coils have been designed to provide efficient error field correction and suppress edge localized modes in SPARC - a compact high-field tokamak that…
Electromagnetic System Conceptual Design for a Negative Triangularity Tokamak
Sophia Guizzo, Mikhail A. Drabinskiy, Christopher Hansen +7
Negative triangularity (NT) tokamak configurations have several key benefits including sufficient core confinement, improved power handling, and reduced edge pressure gradients tha…
