Poloidal Potential in the Low-Collisionality Regime in a Nonaxisymmetric Torus

摘要

The poloidal potential is calculated numerically in the low-collisionality regime for nonaxisymmetric tori such as stellarators and bumpy tori. It is found that even fairly deep into the superbanana regime, the poloidal potential retains the simple azimuthal dependence of the plateau regime. 12 refs., 8 figs. (ERA citation 11:018798)
