One can distinguish '[[Tokamak|tokamak]] divertors' (characterised by toroidal symmetry and one or two X-points or 'nulls') and 'island divertors' (for stellarators). | One can distinguish '[[Tokamak|tokamak]] divertors' (characterised by toroidal symmetry and one or two X-points or 'nulls') and 'island divertors' (for stellarators). | ||

The term 'divertor' can either refer to the magnetic field structure (beyond the X-point and in contact with material surfaces) or to the material structure intersecting the 'outgoing legs' of the magnetic separatrix surface. | |||
