Quasilinear particle transport from gyrokinetic instabilities in general magnetic geometry
Per Helander, Alessandro Zocco
The quasilinear particle flux arising from gyrokinetic instabilities is calculated in the electrostatic and collisionless approximation, keeping the geometry of the magnetic field…

Collisional transport of impurities with flux-surface varying density in stellarators
S. Buller, H. M. Smith, P. Helander +3
High-Z impurities in magnetic confinement devices are prone to develop density variations on the flux-surface, which can significantly affect their transport. In this paper, we gen…

Quasi-axisymmetric magnetic fields: weakly non-axisymmetric case in a vacuum
G. G. Plunk, P. Helander
An asymptotic expansion is performed to obtain quasi-axisymmetric magnetic configurations that are weakly non-axisymmetric. A large space of solutions is identified, which satisfy…
