Abstract
Toroidal (axially asymmetric) (toroidal) divertors which only cause a weak perturbation of the field in a tokamak are proposed. The divertor parameters are found analytically and by numerical simulations. It is shown that the resonant perturbations of the magnetic surfaces can be made small. Possible applications of these divertors as magnetic limiters, for achieving heliotron conditions, and for use with ac tokamaks are discussed.
