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…

Tearing Stability Prediction Combining Toroidal Calculations With a Two-Fluid Slab Layer
D. A. Burgess, N. C. Logan, J. -K. Park +1
A new classical TM stability simulation workflow has been developed that solves the resistive inner-layer equations in a plasma slab to yield a linear, quasi-toroidal TM growth rat…

Error Field Predictability and Consequences for ITER
Matthew Pharr, Nikolas Logan, Carlos Paz-Soldan +2
ITER coil tolerances are re-evaluated using the modern understanding of coupling to least-stable plasma modes and an updated center-line-traced model of ITER's coil windings. This…
