Detailed Description

Approximate \( \mathcal{K}^{Z}_{\vec{\kappa}} \).

\( \mathcal{\hat{K}}^{\hat{Z}}_{\vec{\kappa}} = - \frac{1}{\hat{R} \hat{B}} \)

Note: We implicitly assume the toroidal field line approximation, i.e. all curvature and other perpendicular terms assume that the perpendicular direction lies within the R-Z planes of a cylindrical grid (The plane \( \perp \hat{ e}_\varphi\) )
