Field line diversion properties of finite β-Helias equilibria

The diversion properties of the magnetic field outside the last closed magnetic surface of a Helias stellarator configuration [Phys. Lett. A 114 (1986) 129; Phys. Lett. A 129 (1988) 113] are investigated for finite pressure equilibria. The results indicate that a divertor concept which has been deve...

Description
Summary:The diversion properties of the magnetic field outside the last closed magnetic surface of a Helias stellarator configuration [Phys. Lett. A 114 (1986) 129; Phys. Lett. A 129 (1988) 113] are investigated for finite pressure equilibria. The results indicate that a divertor concept which has been developed from the diversion properties of the corresponding vacuum field can be maintained for finite pressure equilibria. Cross-field particle transport is simulated by a simplified scrape-off layer (SOL) model.
