Comparison of metric components and the magnetic field modulus for NCSX between the FLT (line) and MHD (points) approaches, after the rescalings suggested by Eqs. (88)–(90).
Numerical validation of Eq. (97) (left) and Eq. (100) (right) for NCSX between FLT (line) and MHD (points) approaches.
Numerical comparison of the bad curvature component for NCSX via the MHD (line) and FLT (points) methods.
Scan of growth rates (left) and frequencies (right) over the binormal wavenumber for NCSX using the FLT (line) and MHD (points) settings (, is the sound speed, is the ion Larmor frequency, and is the minor radius).
Numerical evaluation of magnetic shear. The ratio of the metrics (line) is fitted by a straight line (points). The plot in plot presents the same, restricted in the range .
A typical parallel structure of the local shear for NCSX.
Comparison of the anomalous ion heat diffusivity between NCSX (boxes) and DIII-D (line). For the stellarator case, we select five different flux tubes along the toroidal Boozer angle, the first being identical to the fifth, in view of the threefold toroidal symmetry.
